Java Program to Make a Simple Calculator Using switch...case

To understand this example, you should have the knowledge of the following Java programming topics:

• Java Scanner Class

Example: Simple Calculator using Java switch Statement

Here, we have used the Scanner class to take 3 inputs from the user.

• operator - specifies the operation to be performed
• number1/number2 - operands to perform operation on

Since the operator matches the case '*' , so the corresponding codes are executed.

These statements compute the product of two numbers and print the output. Finally, the break statement ends the switch statement.

Similarly, for different operators, different cases are executed.

Sorry about that.

How to Build a Simple Calculator in Java Using Netbeans – Step by Step with Screenshots

• Java Programming for Beginners – Lesson 1: Introduction to Java Netbeans Installation
• Java Programming for Beginners – Lesson 2: Write Your First Program

You can print out this page so that you can easily follow along (you can also open it in a different display)  

What you would need

• Netbeans IDE
• A pen and a paper(optional)

Step 1 : Create an Application in Netbeans. Name the application CalculatorProgram . If you don’t know how to create new application. You can get it here: Your First Java Program .

Step 2 : Add a JFrame Form to the Application Right-click on the name of the application in the Projects tab by the left of the window and Choose New > JFrame Form Enter the name pnlCalculator next to the Class Name and click on Finish. You can see that the form is added as shown below

Step 3 : Add two JPanels to the form and then resize and position them as shown. You can get Panels at the right hand side in the palettes tab.

Step 4a : Place a TextField in the Form See Step 4b to delete the jTextField1. You need to place a TextField on the form, by clicking on TextField from the Palette and clicking in the upper part of the form. Drag to position it as shown in the figure below.

Step 4b: Modify TextField Right-click on the TextField and click on Edit Text. Delete the text there. Right-click again and click on ‘Change Variable Name…’. Delete what is there and enter txtResult

Step 5 : Place and  Buttons on the Form. (Don’t change the name here) You can find buttons on the palette tab. Just add the button, resize them until you have enough buttons on the screen

Step 6: Change the text of the buttons To change the name of a button, right click on the button and choose “Edit Text”. For button 1, just type 1, for button 2, type 2 and so on exactly as it appears below. At the end of this step, your form would look like this

Step 7 : Change the Variable Names of the buttons. To do that, right-click on a button and click “ Change Variable Name “. Change the names according to the outline below. You need to carefully enter the names correctly, otherwise the program may have issues

1-  btn1 2 – btn2 3 – btn3 4 – btn4 5 – btn5 6 – btn6 7 – btn7 8 – btn8 9 – btn9 0 – btn0 +/-  btnPlusMinus CE – btnClear + –  btnPlus –     btnMinus /     btnDivision *     btnMultiplication Step 8: Preview your design Click on the Projects tab, locate the name of the Form. In this case it is pnlCalculator.java . Right-click on it and click on Run File.

You wait for a couple of seconds and if you did everything correctly, the form below would be displayed.

You can then close the preview form.

Step 9 : View your source code and locate where you will write your first code. Once in the code view, you can scroll up a little to find the position where you would write your first code.

Step 10 : Type the code below in the position you identified in Step 9. (You can also copy and paste it there)

static int value1; static int value2; static String operator; Step 11:   Write the code for Button 1(btn1). Right-click on button 1 > Choose Events > Choose Mouse, Choose MouseClicked. This takes you to where you would write the code for button 1  

I have highlighted the position to help you find it(remember you may have to scroll up) You would see something like: Private void btn1MouseClicked…… Below the next line that says…//TODO, you can write your code.  

Step 12: Now Write the code for button 1. This means that we need to write a code to specify what happens when 1 is clicked. To to that: Write the code below in the position as shown in the figure( you can also copy and paste)         if(txtResult.getText().isEmpty())         {             txtResult.setText(btn1.getText());             value1 = 1;                   } else {             txtResult.setText(txtResult.getText()+ ” ” + btn1.getText());             value2 = 1;         } Your code would now look like the one in the figure below:

Step 13: Test Your Program You can test your program using the procedure you applied in Step 8. When the form displays, Click on 1 to see what happens. If you did everything right, 1 would appear in the display. Close the form

Step 14:  Write the code for Button 2(btn2). Right-click on button 2, Choose Events, Choose Mouse, Choose MouseClicked. This takes you to where you would write the code for button 2

Step 15: Write the code below in the position as shown in the figure( you can also copy and paste)

        if(txtResult.getText().isEmpty())         {             txtResult.setText(btn2.getText());             value1 = 2;                   } else {             txtResult.setText(txtResult.getText()+ ” ” + btn2.getText());             value2 = 2;         }

If you have written it in the right position, your code would be as shown in the figure below:

Step 16: Do the same for buttons 3, 4, 5, 6, 7, 8, 9 and 0

Step 17 : Take some time to look through the codes to make sure you got it right. And also get used to various parts of the code. But don’t modify anything!

Step 18: Test the program again

Step 19: Code for the CE (Clear) button Right-click on CE button, choose events, choose Mouse, choose MouseClick. This takes you to where you would write the code for this button. Copy and paste the code below in the position

  txtResult.setText(“”);

This is the code that would clear the display when the CE button is clicked. Very simple, right?

Step 20: Code for the +(plus) and -(minus), /(division) and multiplication buttons

For the plus button, write the code below:

        if(!(txtResult.getText().isEmpty())){         operator = “plus”;         txtResult.setText(txtResult.getText()+ ” +”);         }

For the minus write the code below:

        if(!(txtResult.getText().isEmpty())){         operator = “minus”;         txtResult.setText(txtResult.getText()+ ” -“);         }

For the division button, write the code below

        if(!(txtResult.getText().isEmpty())){         operator = “division”;         txtResult.setText(txtResult.getText()+ ” /”);         }

For the multiplication button, write the code below:

        if(!(txtResult.getText().isEmpty())){         operator = “multiplication”;         txtResult.setText(txtResult.getText()+ ” *”);         } Step 21: Test your program. Run the program, test the 0 – 9 buttons as well as the operations. Also test the clear button Attempt to enter: 4 + 5 and click (=) Note that nothing happens when you click the equals button. Note : you can only work with 1 to 9 at this time Now let’s write code for the equality sign to perform the calculation.

Step 22: Write code for the equality button This is the code for the equality button(you already know how to find where to place this code)

         double answer = 0;          if(operator == “plus”)              answer = value1 + value2;          else if(operator==”minus”)              answer = value1 – value2;          else if (operator ==”multiplication”)              answer = value1 * value2;          else if(operator == “division”)              answer = value1/value2;                   String Result = Double.toString(answer);          txtResult.setText(Result);

Step 23: Test the program (Congratulations!) Run the program and try a few calculations. What are your observations. You can leave a comment in the comment box below to let me know what you observe. Are there some questions, leave it in the comment box below.

Get Ready for the Next Steps In the next tutorials we would tidy up by doing the following:

• Modify this program to handle any number (not just 0 to 9)
• Answer your questions
• Handle errors, in case user enters wrong inputs

I would publish it in a couple of days. Just click follow in the button under my name to get notified when I publish the next step. You can also subscribe to the YouTube channel to watch step by step video

Creating a Calculator using Java AWT

In this Java tutorial,

We will learn how to build a simple calculator using Java AWT. This calculator has some simple functionality like all the basic mathematical operations and some special addon features , we will see as we follow So let’s get started FIRST of all small description on AWT AWT (Abstract Window Toolkit) is an API that helps in building GUI (Graphical User Interface) based java applications. GUI helps in user interactions using some graphics. It primarily consists of a set of classes and methods that are required for creating and managing the GUI in a simplified manner such as buttons , windows , frame , textfield , RadioButton etc I have provided the Java code for the calculator which uses Action listener interface for EventHandling. And yes its not an applet code, which is deprecated

SO what I did is just implemented ActionListener interface in our MyCalc class and in its constructor i Register the AWT components with the Listener and done EventHandling using actionPerformed method. OUR all the logic part in written in this actionPerformed function only which we will see below:

1.FOR NUMERIC BUTTON

when any of the numeric button pressed whatever value in label l1 will be stored in a variable zt and then concatenated with the corresponding number and and then displayed in the label l1 for NEGATIVE and DECIMAL PTS Button we did it similarly

2.FOR AIRTHMETIC BUTTON

NOW here we store the value of label l1 into a variable num1 after converting into double type which will be technically 1st number and then and set label l1 to null

we will just use a check variable for getting that this particular airthmetic button(here + ) was clicked so we can do this operation in our = button

3.FOR EQUALS BUTTON

NOW again store the value of l1 into num2 variable which will be techincally 2nd number and then check the value of variable check and then do corresponding operation and after that display result in label l1

4.FOR CLEAR BUTTON

here updated all the variable we use to its Default value 0 and set label l1 to null so that we can start our new calculation afterward

5.FOR BACKSPACE BUTTON

here just updates the value in l1 by removing last digits using substring function and handled one StringIndexOutOfBoundsException which occur when our value in label is null and still pressing back Button

6.SPECIAL ADDONS FEATURE

what I did is just handled one execption in EQUAL and all AIRTHMETIC Buttons and printed a desired message according to situtation inside AIRTHMETIC BUTTONS :

inside EQUALS BUTTON :

when we was converting the value into the double value, BUT lets say that, label l1 has null value (i.e. label is empty) and we still pressed these button then it will generate NumberFormatException execption, So handled that and printed desired message For eg: If I click 1 then + and then i click - instead of some other numeric button, hence this an invalid format, and when - was clicked at that time label was null hence execption generated so just handled it and printed invalid format in label

SIMILARLY, when label is null ,and = was clicked in that situation ENTER NUMBER FIRST will be displayed inside label

With this, we come to an end of this Java AWT Tutorial. So just go through the code and try it. If you have any difficulty in understanding or using the code, then you ask by commenting below . If you would like to download & run my CALC you can find here I have uploaded both source code & executable jarfile

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:

How to build a basic mortgage calculator in Java

Get Started With Machine Learning

Learn the fundamentals of Machine Learning with this free course. Future-proof your career by adding ML skills to your toolkit — or prepare to land a job in AI or Data Science.

In this shot, we’ll learn to build a mortgage calculator in Java.

Setting up and getting user inputs

First, let’s create our class with the starting point, the main method.

The name for our class is Mortgage . This means that the file containing the source code will also be Mortgage .

Next, we can write the code to get user inputs inside the main method.

We use the Scanner class to get the user input, which is defined in java.util . We import the class and create a new object, stdin .

These are the inputs we need from the user:

• principal: The amount of loan they want to get.
• Annual interest rate in percent.
• period in years: The maximum value is 30 (years).

So, to do this, we first print out the question like:

Note: We use System.out.print() instead of System.out.println() . This is because we want the user answer to be printed next to the question.

After the question, we create a variable and keep the user input. Syntax:

Implement the mortgage logic

To calculate the monthly payment of a mortgage, we use this formula :

M = P r ( 1 + r ) n ( 1 + r ) n − 1 M=P \frac{r(1+r)^{n}}{(1+r)^{n}-1} M = P ( 1 + r ) n − 1 r ( 1 + r ) n ​

• M M M : Monthly payment
• P P P : Principal
• r r r : Monthly rate (divide the annual rate by 12)
• n n n : Number of payments (the number of months you will be paying the loan)

Before calculating the mortgage monthly payment, let’s find the monthly rate and the number of payments.

Now, we can calculate the monthly payment.

First, we calculate 1 + r to the power of n and keep the value into the variable mathPower .

Next, we calculate the monthly payment and assign the value to monthlyPayment .

To format the monthly payment into US dollars, we take the help of NumberFormat . Therefore, we’ll first need to import it like this:

Put all together and print the result

Let’s put all of the above together and run our code.

Improvement

The program above is fine but can still be improved.

Let’s define the numbers 100 and 12 as constants and give them proper names.

Next, we can replace those magic numbers with their variables.

Note: A final variable cannot change.

Congratulations. You have coded your monthly mortgage calculator in Java. Let’s now recall the main point:

• Import packages: import package;
• Get user input: Scanner stdin = new Scanner ( System.in );
• format number: NumberFormat.getCurrencyInstance().format(number);

Happy coding!

Brief history of different grading systems

In 1785, students at Yale were ranked based on "optimi" being the highest rank, followed by second optimi, inferiore (lower), and pejores (worse). At William and Mary, students were ranked as either No. 1, or No. 2, where No. 1 represented students that were first in their class, while No. 2 represented those who were "orderly, correct and attentive." Meanwhile at Harvard, students were graded based on a numerical system from 1-200 (except for math and philosophy where 1-100 was used). Later, shortly after 1883, Harvard used a system of "Classes" where students were either Class I, II, III, IV, or V, with V representing a failing grade. All of these examples show the subjective, arbitrary, and inconsistent nature with which different institutions graded their students, demonstrating the need for a more standardized, albeit equally arbitrary grading system.

In 1887, Mount Holyoke College became the first college to use letter grades similar to those commonly used today. The college used a grading scale with the letters A, B, C, D, and E, where E represented a failing grade. This grading system however, was far stricter than those commonly used today, with a failing grade being defined as anything below 75%. The college later re-defined their grading system, adding the letter F for a failing grade (still below 75%). This system of using a letter grading scale became increasingly popular within colleges and high schools, eventually leading to the letter grading systems typically used today. However, there is still significant variation regarding what may constitute an A, or whether a system uses plusses or minuses (i.e. A+ or B-), among other differences.

An alternative to the letter grading system

Letter grades provide an easy means to generalize a student's performance. They can be more effective than qualitative evaluations in situations where "right" or "wrong" answers can be easily quantified, such as an algebra exam, but alone may not provide a student with enough feedback in regards to an assessment like a written paper (which is much more subjective).

Although a written analysis of each individual student's work may be a more effective form of feedback, there exists the argument that students and parents are unlikely to read the feedback, and that teachers do not have the time to write such an analysis. There is precedence for this type of evaluation system however, in Saint Ann's School in New York City, an arts-oriented private school that does not have a letter grading system. Instead, teachers write anecdotal reports for each student. This method of evaluation focuses on promoting learning and improvement, rather than the pursuit of a certain letter grade in a course. For better or for worse however, these types of programs constitute a minority in the United States, and though the experience may be better for the student, most institutions still use a fairly standard letter grading system that students will have to adjust to. The time investment that this type of evaluation method requires of teachers/professors is likely not viable on university campuses with hundreds of students per course. As such, although there are other high schools such as Sanborn High School that approach grading in a more qualitative way, it remains to be seen whether such grading methods can be scalable. Until then, more generalized forms of grading like the letter grading system are unlikely to be entirely replaced. However, many educators already try to create an environment that limits the role that grades play in motivating students. One could argue that a combination of these two systems would likely be the most realistic, and effective way to provide a more standardized evaluation of students, while promoting learning.
