What is the purpose of a ButtonGroup object?

A ButtonGroup object is a class available in some programming languages, such as Java, which is used to group a set of buttons together. These buttons are typically radio buttons or toggle buttons. The main purpose of a ButtonGroup object is to ensure that only one button within the group can be selected at a time. This is useful when creating graphical user interfaces (GUIs) where the user is required to choose one option among multiple choices.

When a ButtonGroup object is used, the behavior of the radio buttons or toggle buttons is controlled. When a button in the group is selected, any other selected button within the group is automatically deselected. This means that only one button can be selected at a time within the group, preventing the user from choosing multiple options simultaneously.

ButtonGroup objects are often used in user interfaces (UIs) where the user needs to make a single choice among multiple options. Examples include selecting a payment method, choosing a date range, or picking a specific category in a questionnaire. The ButtonGroup object makes the process of coding and managing user interaction with these buttons simpler and more efficient.

There are several benefits to using ButtonGroup objects in your code: 1. Simplify coding: By using ButtonGroup objects to group radio buttons or toggle buttons, you don't need to manually handle the deselection of other buttons in the group when a new button is selected. 2. Improve user experience: ButtonGroup objects ensure consistent behavior of radio buttons or toggle buttons, which provides a better user experience as the user can clearly see which option they have selected. 3. Reduce programming errors: By managing the selection process, ButtonGroup objects help reduce the chance of programming errors, such as allowing multiple selections when only one should be allowed. So, the purpose of a ButtonGroup object is to simplify the process of managing a group of buttons, ensuring only one button can be selected at a time, and providing a consistent user experience for graphical user interfaces.
