Event handling is an important concept in Java programming that allows applications to respond to user actions such as mouse clicks, key presses, and checkbox selections. In Java AWT (Abstract Window Toolkit), event handling is used to make graphical user interface (GUI) applications interactive. Hesi practice test are freely available at Quiz RN.
A checkbox is a GUI component that allows users to select or deselect an option. In Java AWT, the Checkbox class is used to create checkboxes, while the ItemListener interface can be used to detect changes in their selection state. When a user selects or deselects a checkbox, an item event is generated and handled by the appropriate listener.
For example, a Java application may use checkboxes to allow users to select their favorite programming languages. The application can detect the selected options and display the results accordingly.
