a) The MouseAdapter class implements all of the methods of the MouseListener interface as do-nothing methods, eliminating the need to implement the MouseListener interface.
b) The MouseAdapter class allows your program to accept input from multiple mice.
c) The MouseAdapter class implements all of the methods of the ActionListener interface as do-nothing methods, eliminating the need to implement the ActionListener interface.
d) A class can implement the MouseAdapter class to handle mouse events.

Answer 1

Option D, The MouseAdapter class is a class in the Java Swing library that provides functionality for handling mouse events.

Step-by-step explanation:

The MouseAdapter class is a class in the Java Swing library that provides functionality for handling mouse events. It is used when you want to handle only one or a few specific types of mouse events without implementing all the methods of the MouseListener interface. By extending the MouseAdapter class, you can override only the specific methods you need.

For example, if you are only interested in handling the mouse click event, you can extend the MouseAdapter class and override the mouseClicked() method. The remaining methods of the MouseListener interface provided by the MouseAdapter class are already implemented as do-nothing methods.

So, the correct answer is option D. A class can implement the MouseAdapter class to handle mouse events.
