I am using NetBeans IDE for creating Java application. To create this application, follow the below
given steps:
Launch NetBeans, select File->New Project option.
The Choose Project dialog box will open up. Because, we want to make a Java desktop application,
select "Java" option from the Categories pane and "Java Application" option from the Projects pane.
Select Next button to move further. The next dialog box will ask the Java application's name and the
location on the drive where we want to create the application. Let us assign the name,
"checkBoxDemoApp" to this java application and let the location be the default location as shown in
below figure.

Click Finish button to create the application. The NetBeans IDE will automatically create a Java class
file for you by name, CheckBoxDemoApp.java with some default code. The Projects window will
appear as shown below:

To create a GUI (Graphical User Interface), we will be using Java Swing toolkit. To work with Java
Swing toolkit, you need to add a JFrame form to the application. Hence, right click the package,
checkboxdemoapp in the Source Packages node in the Projects window and select New->JFrame
Form option from the context menu that pops up. You will be asked to specify the class name for the
new JFrame form. Let us enter FastFood as the class name. Keeping the rest of text boxes in the
dialog box to their default values, click Finish button to create a JFrame form.
