What are default methods in Java interfaces?

Can you explain what default methods are in Java interfaces?

Sure! Default methods in Java interfaces allow you to add new methods to interfaces without breaking existing implementations. They provide a default implementation that can be overridden by implementing classes.

Why were default methods introduced in Java?

Default methods were introduced in Java 8 to support the evolution of interfaces. They allow developers to add new functionality to interfaces while maintaining backward compatibility.

Can you give me an example of a default method?

Of course! Here's a simple example:

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

How do default methods affect multiple inheritance?

Default methods help resolve the diamond problem in multiple inheritance by allowing classes to inherit method implementations from interfaces, while still requiring them to provide their own implementations if needed.
