How do I override default methods in Java?

How do I override default methods in Java?

In Java, you can override default methods in interfaces by providing a new implementation in the class that implements the interface.

Can you give me an example of overriding a default method?

Sure! If you have an interface like MyInterface with a default method defaultMethod(), you can override it in your class like this:

public class MyClass implements MyInterface {
    @Override
    public void defaultMethod() {
        System.out.println("Overridden default method.");
    }
}

What happens if I don't override the default method?

If you don't override the default method, the implementation from the interface will be used when you call that method on an instance of your class.

Are there any restrictions on overriding default methods?

Yes, you must ensure that the method signature matches the default method in the interface, and you cannot override it in a final class.
