What are some examples of anonymous classes in Java?

Anonymous classes in Java are used to instantiate classes that may not be reused elsewhere. For example, you can create an anonymous class to implement an interface or extend a class on the fly.

Can you show me a code example?

Sure! Here's a simple example:

Button button = new Button();
button.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        System.out.println("Button clicked!");
    }
});

What are the advantages of using anonymous classes?

Anonymous classes allow for concise code and can be used to override methods without creating a separate named class. They are great for event handling and callbacks.

Are there any limitations to using anonymous classes?

Yes, anonymous classes cannot have explicit constructors, and they can only extend one class or implement one interface. They also make the code less readable if overused.
