B. use an anonymous class to implement a callback.
C. use an anonymous class when all methods of the class will be static methods.
D. use an anonymous class when the program will only need one object of the class.

Answer 1

A good use for an anonymous class is to implement a callback.option b.

Step-by-step explanation:

A good use for an anonymous class is B. to implement a callback. An anonymous class allows you to define and implement a single-use class without giving it a name and is typically used when you need to pass a behavior (callback) as an argument to another method or function.

For example, you can create an anonymous class to implement a click listener in a graphical user interface (GUI) application. Instead of creating a separate class for the click listener, you can directly define it as an anonymous class when registering the listener.

This approach makes the code more concise and easier to manage as you don't need to create a separate class for every use case of a callback.
