getInt()
getSource()
getEvent()
getListener()
Solution
Answer
The method from the ActionEvent class used to fetch the identity of the event source in Java GUI is getSource().
In Java's event handling mechanism, when an event occurs (like a button click), an ActionEvent object is created. This object is associated with the event source, which is typically the component that triggered the event, such as a button. The getSource()
method of the ActionEvent class allows you to retrieve a reference to this event source component. This can be particularly useful when you have multiple components (like buttons) that fire similar events, and you need to determine which specific component triggered the event.
In summary, getSource()
provides a way to access the object that generated the event, allowing for appropriate responses to user interactions in a GUI application.
