assignment operator in java array

The Java Tutorials have been written for JDK 8. Examples and practices described in this page don't take advantage of improvements introduced in later releases and might use technology no longer available. See Java Language Changes for a summary of updated language features in Java SE 9 and subsequent releases. See JDK Release Notes for information about new features, enhancements, and removed or deprecated options for all JDK releases.

Assignment, Arithmetic, and Unary Operators

The simple assignment operator.

One of the most common operators that you'll encounter is the simple assignment operator " = ". You saw this operator in the Bicycle class; it assigns the value on its right to the operand on its left:

This operator can also be used on objects to assign object references , as discussed in Creating Objects .

The Arithmetic Operators

The Java programming language provides operators that perform addition, subtraction, multiplication, and division. There's a good chance you'll recognize them by their counterparts in basic mathematics. The only symbol that might look new to you is " % ", which divides one operand by another and returns the remainder as its result.

The following program, ArithmeticDemo , tests the arithmetic operators.

This program prints the following:

You can also combine the arithmetic operators with the simple assignment operator to create compound assignments . For example, x+=1; and x=x+1; both increment the value of x by 1.

The + operator can also be used for concatenating (joining) two strings together, as shown in the following ConcatDemo program:

By the end of this program, the variable thirdString contains "This is a concatenated string.", which gets printed to standard output.

The Unary Operators

The unary operators require only one operand; they perform various operations such as incrementing/decrementing a value by one, negating an expression, or inverting the value of a boolean.

The following program, UnaryDemo , tests the unary operators:

The increment/decrement operators can be applied before (prefix) or after (postfix) the operand. The code result++; and ++result; will both end in result being incremented by one. The only difference is that the prefix version ( ++result ) evaluates to the incremented value, whereas the postfix version ( result++ ) evaluates to the original value. If you are just performing a simple increment/decrement, it doesn't really matter which version you choose. But if you use this operator in part of a larger expression, the one that you choose may make a significant difference.

The following program, PrePostDemo , illustrates the prefix/postfix unary increment operator:

Types of Assignment Operators in Java

• Simple Assignment Operator: The Simple Assignment Operator is used with the "=" sign, where the operand is on the left side and the value is on the right. The right-side value must be of the same data type as that defined on the left side.
• Compound Assignment Operator:  Compound assignment operators combine arithmetic operations with assignments. They provide a concise way to perform an operation and assign the result to the variable in one step. The Compound Operator is utilized when +,-,*, and / are used in conjunction with the = operator.

1. Simple Assignment Operator (=):

The equal sign (=) is the basic assignment operator in Java. It is used to assign the value on the right-hand side to the variable on the left-hand side.

Assignment Operator in Java with Example

Assignment operator is one of the simplest and most used operator in java programming language. As the name itself suggests, the assignment operator is used to assign value inside a variable. In java we can divide assignment operator in two types :

• Assignment operator or simple assignment operator
• Compound assignment operators

What is assignment operator in java

The = operator in java is known as assignment or simple assignment operator. It assigns the value on its right side to the operand(variable) on its left side. For example :

The left-hand side of an assignment operator must be a variable while the right side of it should be a value which can be in the form of a constant value, a variable name, an expression, a method call returning a compatible value or a combination of these.

The value at right side of assignment operator must be compatible with the data type of left side variable, otherwise compiler will throw compilation error. Following are incorrect assignment :

Another important thing about assignment operator is that, it is evaluated from right to left . If there is an expression at right side of assignment operator, it is evaluated first then the resulted value is assigned in left side variable.

Here in statement int x = a + b + c; the expression a + b + c is evaluated first, then the resulted value( 60 ) is assigned into x . Similarly in statement a = b = c , first the value of c which is 30 is assigned into b and then the value of b which is now 30 is assigned into a .

The variable at left side of an assignment operator can also be a non-primitive variable. For example if we have a class MyFirstProgram , we can assign object of MyFirstProgram class using = operator in MyFirstProgram type variable.

Is == an assignment operator ?

No , it's not an assignment operator, it's a relational operator used to compare two values.

Is assignment operator a binary operator

Yes , as it requires two operands.

Assignment operator program in Java

a = 2 b = 2 c = 4 d = 4 e = false

Java compound assignment operators

The assignment operator can be mixed or compound with other operators like addition, subtraction, multiplication etc. We call such assignment operators as compound assignment operator. For example :

Here the statement a += 10; is the short version of a = a + 10; the operator += is basically addition compound assignment operator. Similarly b *= 5; is short version of b = b * 5; the operator *= is multiplication compound assignment operator. The compound assignment can be in more complex form as well, like below :

List of all assignment operators in Java

The table below shows the list of all possible assignment(simple and compound) operators in java. Consider a is an integer variable for this table.

How many assignment operators are there in Java ?

Including simple and compound assignment we have total 12 assignment operators in java as given in above table.

What is shorthand operator in Java ?

Shorthand operators are nothing new they are just a shorter way to write something that is already available in java language. For example the code a += 5 is shorter way to write a = a + 5 , so += is a shorthand operator. In java all the compound assignment operator(given above) and the increment/decrement operators are basically shorthand operators.

Compound assignment operator program in Java

a = 20 b = 80 c = 30 s = 64 s2 = 110 b2 = 15

What is the difference between += and =+ in Java?

An expression a += 1 will result as a = a + 1 while the expression a =+ 1 will result as a = +1 . The correct compound statement is += , not =+ , so do not use the later one.

Operators are used to perform operations on variables and values.

In the example below, we use the + operator to add together two values:

Try it Yourself »

Although the + operator is often used to add together two values, like in the example above, it can also be used to add together a variable and a value, or a variable and another variable:

Java divides the operators into the following groups:

• Arithmetic operators
• Assignment operators
• Comparison operators
• Logical operators
• Bitwise operators

Arithmetic Operators

Arithmetic operators are used to perform common mathematical operations.

Java Assignment Operators

Assignment operators are used to assign values to variables.

In the example below, we use the assignment operator ( = ) to assign the value 10 to a variable called x :

The addition assignment operator ( += ) adds a value to a variable:

A list of all assignment operators:

Java Comparison Operators

Comparison operators are used to compare two values (or variables). This is important in programming, because it helps us to find answers and make decisions.

The return value of a comparison is either true or false . These values are known as Boolean values , and you will learn more about them in the Booleans and If..Else chapter.

In the following example, we use the greater than operator ( > ) to find out if 5 is greater than 3:

Java Logical Operators

You can also test for true or false values with logical operators.

Logical operators are used to determine the logic between variables or values:

Java Bitwise Operators

Bitwise operators are used to perform binary logic with the bits of an integer or long integer.

Note: The Bitwise examples above use 4-bit unsigned examples, but Java uses 32-bit signed integers and 64-bit signed long integers. Because of this, in Java, ~5 will not return 10. It will return -6. ~00000000000000000000000000000101 will return 11111111111111111111111111111010

In Java, 9 >> 1 will not return 12. It will return 4. 00000000000000000000000000001001 >> 1 will return 00000000000000000000000000000100

Understanding the Java += (Addition Assignment) Operator

Stumped by the ‘+=’ operator in Java? You’re not alone. Many developers find this operator a bit puzzling, but it’s actually a handy tool that can simplify your code and make your programming tasks easier.

Think of the ‘+=’ operator in Java as a mathematical shortcut – a bridge that connects your variables and values in a more efficient way. It’s a powerful tool that can streamline your code, making it more readable and maintainable.

In this guide, we’ll walk you through the process of understanding and using the ‘+=’ operator in Java , from the basics to more advanced techniques. We’ll cover everything from simple assignments and calculations to its use with strings and arrays, and even discuss alternative approaches.

So, let’s dive in and start mastering the ‘+=’ operator in Java!

TL;DR: What Does ‘+=’ Mean in Java?

In Java, the ‘+=’ represents the additional assignment operator and is used to add the right operand to the left operand and assign the result back to the left operand, with the syntax, operandA += operandB . It’s a shorthand for a common operation that can make your code more concise and easier to read.

Here’s a simple example:

In this example, we declare an integer a and assign it a value of 5. Then, we use the ‘+=’ operator to add 3 to a and assign the result back to a . When we print out a , the output is 8.

This is just a basic use of the ‘+=’ operator in Java, but there’s much more to learn about this operator and how it can simplify your code. Continue reading for more detailed information and advanced usage scenarios.

Table of Contents

The Basics of ‘+=’ in Java

Advanced uses of ‘+=’ in java, exploring alternatives to ‘+=’ in java, troubleshooting java ‘+=’ operator issues, digging into java operators, applying ‘+=’ operator in larger java projects, wrapping up: additional assignment ‘+=’ operator.

The ‘+=’ operator in Java is a compound assignment operator. It’s a shorthand that combines the addition and assignment operations into a single operation. This operator adds the right operand to the left operand and then assigns the result back to the left operand.

Let’s look at a simple example:

In this example, we declare an integer b and assign it a value of 10. Then, we use the ‘+=’ operator to add 5 to b and assign the result back to b . When we print out b , the output is 15.

Advantages of Using ‘+=’

One of the main advantages of using the ‘+=’ operator is that it can make your code more concise and easier to read. Instead of writing b = b + 5; , you can simply write b += 5; .

Pitfalls to Avoid

While the ‘+=’ operator can simplify your code, it’s important to be aware of potential pitfalls. For example, if you use the ‘+=’ operator with a null value, you’ll get a NullPointerException. It’s also important to remember that the ‘+=’ operator performs an implicit cast, which can lead to unexpected results if you’re not careful.

Here’s an example:

In this example, the ‘+=’ operator performs an implicit cast from int (the type of the right operand) to byte (the type of the left operand). The result is -116, which might not be what you expected.

While the ‘+=’ operator is commonly used with numeric types, it can also be used with other types in Java, such as strings and arrays. This versatility can lead to more complex and interesting use cases.

‘+=’ with Strings

In Java, the ‘+=’ operator can be used to concatenate strings. Here’s an example:

In this example, we declare a string s and assign it a value of “Java”. Then, we use the ‘+=’ operator to append ” programming” to s . When we print out s , the output is “Java programming”.

‘+=’ with Arrays

The ‘+=’ operator can also be used with arrays in Java. However, it’s important to note that this usage is not as straightforward as with numeric types or strings. Here’s an example:

In this example, we declare an array and use a for loop to iterate through each element. We use the ‘+=’ operator to add 5 to each element in the array. When we print out the elements of the array, the output is 6, 7, 8.

These advanced uses of the ‘+=’ operator can help you write more efficient and concise code in Java, especially when working with strings and arrays.

While the ‘+=’ operator is a powerful tool in Java, there are other related operators that you can use depending on the specific needs of your code. Understanding these alternatives can give you more flexibility and control over your code.

The ‘+’ Operator

The ‘+’ operator in Java is the most basic form of addition. It adds the right operand to the left operand.

In this example, we’re doing the same thing as c += 3; , but we’re writing it out in a longer form. The ‘+’ operator is straightforward and easy to understand, but it can make your code more verbose.

The ‘++’ Operator

The ‘++’ operator in Java is an increment operator. It increases the value of the variable by 1.

In this example, we’re increasing the value of d by 1. The ‘++’ operator is a concise way to increment a variable, but it’s limited to increasing the value by 1.

Decision-Making Considerations

When deciding which operator to use, consider the needs of your code and the readability of your code. The ‘+=’ operator can make your code more concise, but it might be less clear to someone who isn’t familiar with this operator. The ‘+’ and ‘++’ operators are more explicit, but they can make your code more verbose.

Understanding these alternatives to the ‘+=’ operator can help you write more efficient and readable code in Java.

While the ‘+=’ operator in Java is a powerful tool, it’s not without its potential pitfalls. Understanding these common issues and how to address them can save you time and frustration.

Dealing with Null Values

One common issue is attempting to use the ‘+=’ operator with a null value. This will result in a NullPointerException.

In this example, we attempt to use the ‘+=’ operator to append ” programming” to a null string. This results in a NullPointerException. To avoid this, always ensure that your variables are initialized before using them with the ‘+=’ operator.

Implicit Casting

Another common issue is the implicit casting that occurs when using the ‘+=’ operator. This can lead to unexpected results.

In this example, the ‘+=’ operator performs an implicit cast from int (the type of the right operand) to byte (the type of the left operand), resulting in an unexpected value. To avoid this, be mindful of the types of your variables and the potential for implicit casting.

Optimization Tips

While the ‘+=’ operator can make your code more concise, it’s not always the most efficient choice. For example, if you’re performing a large number of additions, it might be more efficient to use a StringBuilder when working with strings, or to use a loop or a built-in method when working with arrays.

Understanding these common issues and best practices can help you use the ‘+=’ operator more effectively in Java.

Operators in Java are special symbols that perform specific operations on one, two, or three operands, and then return a result. They are the building blocks of any Java program, allowing us to perform calculations, manipulate bits, compare values, and more.

The Role of Operators in Java

Operators play a pivotal role in Java programming. They allow us to perform basic mathematical operations like addition ( + ), subtraction ( - ), multiplication ( * ), and division ( / ). They also let us compare values and determine logic ( == , != , > , < , && , || ), manipulate bits ( <> , & , | ), and more.

The Importance of ‘+=’ Operator

Among these operators, ‘+=’ holds a special place due to its dual functionality. It’s a compound assignment operator that performs both addition and assignment in a single step. This not only makes our code more concise but also can lead to performance improvements in certain situations.

In this example, we use the ‘+=’ operator to add 5 to x and assign the result back to x in a single step. This is more efficient than performing the addition and assignment in two separate steps.

The ‘+=’ Operator in the Broader Context of Java

The ‘+=’ operator is part of a family of compound assignment operators in Java, which also includes ‘-=’, ‘*=’, ‘/=’, and more. These operators all combine an arithmetic operation with an assignment, making our code more concise and potentially more efficient.

Understanding the ‘+=’ operator and its role in Java programming is key to mastering Java and writing efficient, readable code.

The ‘+=’ operator is not just for small programs or quick scripts. It can be a valuable tool in larger Java projects, where code efficiency and readability become critical.

In large codebases, the ‘+=’ operator can help simplify complex calculations and assignments, making the code easier to understand and maintain. It can also reduce the chance of errors, as it reduces the need to repeat variable names.

Related Topics to Explore

The ‘+=’ operator often accompanies several related topics in typical use cases. Understanding these related concepts can provide a more holistic view of Java programming. These include other compound assignment operators like ‘-=’, ‘*=’, ‘/=’, and ‘%=’, as well as the broader topic of operator precedence in Java.

In Python programming, Operators in general are used to perform operations on values and variables. These are standard symbols used for logical and arithmetic operations. In this article, we will look into different types of Python operators. 

• OPERATORS: These are the special symbols. Eg- + , * , /, etc.
• OPERAND: It is the value on which the operator is applied.

Arithmetic Operators in Python

Python Arithmetic operators are used to perform basic mathematical operations like addition, subtraction, multiplication , and division .

In Python 3.x the result of division is a floating-point while in Python 2.x division of 2 integers was an integer. To obtain an integer result in Python 3.x floored (// integer) is used.

Example of Arithmetic Operators in Python

Division operators.

In Python programming language Division Operators allow you to divide two numbers and return a quotient, i.e., the first number or number at the left is divided by the second number or number at the right and returns the quotient. 

There are two types of division operators: 

Float division

• Floor division

The quotient returned by this operator is always a float number, no matter if two numbers are integers. For example:

Example: The code performs division operations and prints the results. It demonstrates that both integer and floating-point divisions return accurate results. For example, ’10/2′ results in ‘5.0’ , and ‘-10/2’ results in ‘-5.0’ .

Integer division( Floor division)

The quotient returned by this operator is dependent on the argument being passed. If any of the numbers is float, it returns output in float. It is also known as Floor division because, if any number is negative, then the output will be floored. For example:

Example: The code demonstrates integer (floor) division operations using the // in Python operators . It provides results as follows: ’10//3′ equals ‘3’ , ‘-5//2’ equals ‘-3’ , ‘ 5.0//2′ equals ‘2.0’ , and ‘-5.0//2’ equals ‘-3.0’ . Integer division returns the largest integer less than or equal to the division result.

Precedence of Arithmetic Operators in Python

The precedence of Arithmetic Operators in Python is as follows:

• P – Parentheses
• E – Exponentiation
• M – Multiplication (Multiplication and division have the same precedence)
• D – Division
• A – Addition (Addition and subtraction have the same precedence)
• S – Subtraction

The modulus of Python operators helps us extract the last digit/s of a number. For example:

• x % 10 -> yields the last digit
• x % 100 -> yield last two digits

Arithmetic Operators With Addition, Subtraction, Multiplication, Modulo and Power

Here is an example showing how different Arithmetic Operators in Python work:

Example: The code performs basic arithmetic operations with the values of ‘a’ and ‘b’ . It adds (‘+’) , subtracts (‘-‘) , multiplies (‘*’) , computes the remainder (‘%’) , and raises a to the power of ‘b (**)’ . The results of these operations are printed.

Note: Refer to Differences between / and // for some interesting facts about these two Python operators.

Comparison of Python Operators

In Python Comparison of Relational operators compares the values. It either returns True or False according to the condition.

= is an assignment operator and == comparison operator.

Precedence of Comparison Operators in Python

In Python, the comparison operators have lower precedence than the arithmetic operators. All the operators within comparison operators have the same precedence order.

Example of Comparison Operators in Python

Let’s see an example of Comparison Operators in Python.

Example: The code compares the values of ‘a’ and ‘b’ using various comparison Python operators and prints the results. It checks if ‘a’ is greater than, less than, equal to, not equal to, greater than, or equal to, and less than or equal to ‘b’ .

Logical Operators in Python

Python Logical operators perform Logical AND , Logical OR , and Logical NOT operations. It is used to combine conditional statements.

Precedence of Logical Operators in Python

The precedence of Logical Operators in Python is as follows:

• Logical not
• logical and

Example of Logical Operators in Python

The following code shows how to implement Logical Operators in Python:

Example: The code performs logical operations with Boolean values. It checks if both ‘a’ and ‘b’ are true ( ‘and’ ), if at least one of them is true ( ‘or’ ), and negates the value of ‘a’ using ‘not’ . The results are printed accordingly.

Bitwise Operators in Python

Python Bitwise operators act on bits and perform bit-by-bit operations. These are used to operate on binary numbers.

Precedence of Bitwise Operators in Python

The precedence of Bitwise Operators in Python is as follows:

• Bitwise NOT
• Bitwise Shift
• Bitwise AND
• Bitwise XOR

Here is an example showing how Bitwise Operators in Python work:

Example: The code demonstrates various bitwise operations with the values of ‘a’ and ‘b’ . It performs bitwise AND (&) , OR (|) , NOT (~) , XOR (^) , right shift (>>) , and left shift (<<) operations and prints the results. These operations manipulate the binary representations of the numbers.

Python Assignment operators are used to assign values to the variables.

Let’s see an example of Assignment Operators in Python.

Example: The code starts with ‘a’ and ‘b’ both having the value 10. It then performs a series of operations: addition, subtraction, multiplication, and a left shift operation on ‘b’ . The results of each operation are printed, showing the impact of these operations on the value of ‘b’ .

Identity Operators in Python

In Python, is and is not are the identity operators both are used to check if two values are located on the same part of the memory. Two variables that are equal do not imply that they are identical. 

Example Identity Operators in Python

Let’s see an example of Identity Operators in Python.

Example: The code uses identity operators to compare variables in Python. It checks if ‘a’ is not the same object as ‘b’ (which is true because they have different values) and if ‘a’ is the same object as ‘c’ (which is true because ‘c’ was assigned the value of ‘a’ ).

Membership Operators in Python

In Python, in and not in are the membership operators that are used to test whether a value or variable is in a sequence.

Examples of Membership Operators in Python

The following code shows how to implement Membership Operators in Python:

Example: The code checks for the presence of values ‘x’ and ‘y’ in the list. It prints whether or not each value is present in the list. ‘x’ is not in the list, and ‘y’ is present, as indicated by the printed messages. The code uses the ‘in’ and ‘not in’ Python operators to perform these checks.

in Python, Ternary operators also known as conditional expressions are operators that evaluate something based on a condition being true or false. It was added to Python in version 2.5. 

It simply allows testing a condition in a single line replacing the multiline if-else making the code compact.

Syntax :   [on_true] if [expression] else [on_false] 

Examples of Ternary Operator in Python

The code assigns values to variables ‘a’ and ‘b’ (10 and 20, respectively). It then uses a conditional assignment to determine the smaller of the two values and assigns it to the variable ‘min’ . Finally, it prints the value of ‘min’ , which is 10 in this case.

In Python, Operator precedence and associativity determine the priorities of the operator.

Operator Precedence in Python

This is used in an expression with more than one operator with different precedence to determine which operation to perform first.

Let’s see an example of how Operator Precedence in Python works:

Example: The code first calculates and prints the value of the expression 10 + 20 * 30 , which is 610. Then, it checks a condition based on the values of the ‘name’ and ‘age’ variables. Since the name is “ Alex” and the condition is satisfied using the or operator, it prints “Hello! Welcome.”

Operator Associativity in Python

If an expression contains two or more operators with the same precedence then Operator Associativity is used to determine. It can either be Left to Right or from Right to Left.

The following code shows how Operator Associativity in Python works:

Example: The code showcases various mathematical operations. It calculates and prints the results of division and multiplication, addition and subtraction, subtraction within parentheses, and exponentiation. The code illustrates different mathematical calculations and their outcomes.
