Program Plan Intro

Radio buttons:

Radio buttons are buttons which are used to select one choice from several possible options. In java, the programmer use the predefined class “JRadioButton” to create the radio buttons. The general format of “JRadioButton” is:

JRadioButton(String text)

Here,

• “JRadioButton” is the class name.
• “text” is the text present next to the radio button in type of “String”.

If the programmer want to select the radio button initially, use the following format:

JRadioButton(String text, boolean selected)

Here,

• “boolean selected” is the argument to indicate the radio button is selected or not.
  • If the button is selected, mention “true” otherwise “false”.
