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 given below:

  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, the following format is used:

  JRadioButton(String text, boolean selected)

Here,

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