What is the purpose of a ButtonGroup object?

Short Answer

Expert verified
Answer: The purpose of a ButtonGroup object in Java Swing library is to logically group together multiple JRadioButton, JCheckBox, or other similar buttons, allowing only one of them to be selected at a time. It ensures that only one button within the group can be active or selected, so when a new button is selected, the others are deselected automatically. This is most useful in forms or user interfaces where the user is prompted to choose only one option from a list of alternatives, avoiding any confusion or inconsistency in the user's input.
