How do I use default methods in interfaces?

Default methods in interfaces allow you to provide a default implementation for a method. This means that classes implementing the interface can either use the default implementation or override it.

Can you give me an example of a default method?

Sure! Here's a simple example:

interface MyInterface {
    default void myDefaultMethod() {
        System.out.println("This is the default method.");
    }
}

class MyClass implements MyInterface {
    // MyClass can use the default method or override it.
}

What happens if I override the default method?

If you override the default method in your class, the overridden version will be called instead of the default implementation.

Are there any limitations to using default methods?

Yes, default methods cannot be static or private, and they cannot change the method signature defined in the interface.
