BLUEJ PROGRAM FOR CALCULATOR CODE

JRadioButton offRadioButton = new JRadioButton('off') JRadioButton onRadioButton = new JRadioButton('on')

After creating object of all the components, we will set some of the properties of each component like setting their size, location and some other properties and after setting their properties we will finally add them to the frame(Window) using the add() method.

One label for displaying the calculation.

Two radio buttons for switching between on and off.

A text field for displaying the result.

In this step, we will create object of all the components that we want to add to our window like,.

Now the next thing we have to do is to add components to it.

Now as you can see that we have successfully created our display.

After that, we need to run or program.

Create an object of the JFrame class and set some of its properties like its title, visibility, background color, layout property etc.

Now we will create a display window or frame for our calculator.

So friends, lets get started with our tutorial Simple Calculator Program in Java Using Swing or can say simple calculator program in Java using JFrame/frame step by step. It doesnвЂ™t matter whatever IDE or editor you will use the programming logic will be the same.

You can use any IDE like IntelliJ IDEA, Eclipse or you can just use notepad++ to code your program. I will use NetBeansIDE(integrated development environment) for the coding part of my calculator program.

If you already know about Basic Components of Java Swing, then itвЂ™s not going to be very difficult for you. It can also be used for finding the square, square root and reciprocal of any number.Д«efore starting this tutorial, I assume that you have the basic concept of swing components and also you should have the idea of JButton Click Eventmeans what should be the response of a button when we click on it. This is going to be a simple GUI calculator app which will perform basic arithmetic operations like addition, subtraction, multiplication, division etc. This is going to be our first application using swing programming. HeightInMeters = ((feet * 12) + inches) * 0.Hello friends today we will learn how we can create a Simple Calculator Program in Java Using Swing with Source Code. Below code converts feet and inches to meters. So, you can take the height in feet and inches and later convert it into the meters. Normally we measure height in feet and inches. The output for the different-test cases are:. Public static String bmiCategory(double weight,Дouble bmi = weight / ( height * height) The person who wants to lose their want can use a weight loss calculator which can tell the daily caloric requirements, and many easy tips to lose weight. The following table shows the main BMI categories, BMI Range Category 30 ObeseД«MI calculator finds whether the person is underweight, normal, overweight, or obese. Its value is in a specific range for a healthy individual. Using the range of BMI, individuals are classified as underweight, normal or overweight. It can be calculated by taking the weight in kilograms and dividing it by the square of your height in meters.ДЇormula for Calculating BMI in Metric Units,Д«MI = (Weight in Kg) / (Height in Meters * Height in Meters) It is a measure of health based on height and weight. Now in this post, we will develop a Java program for a BMI calculator. Previously we have developed a Java program for Simple calculator using switch cases and methods.
