JRadioButton & ItemListener

Our example shows three radio buttons in a form. A user can select any one of these radio buttons and only one radio button will be in the selected state. Above, the radio button three is in the selected state. When a radio button is in checked (selected) state, our example will flash a message box stating which radio button is in the selected state. Here in this example, we will create all these radio buttons using JRadioButton component of the Java Swing.
