How do I define default methods in interfaces?

How do I define default methods in interfaces?

In Java, you can define default methods in interfaces using the 'default' keyword. For example:

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

Can you give me an example of how to use a default method?

Sure! Here's how you can implement the interface and use the default method:

public class MyClass implements MyInterface {
    public void myClassMethod() {
        myDefaultMethod(); // Calls the default method
    }
}

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 one.

Are default methods supported in all versions of Java?

Default methods were introduced in Java 8, so they are not available in earlier versions.
