What are default methods in Java?

What are default methods in Java?

Default methods in Java are methods defined in an interface with a default implementation. They allow interfaces to evolve without breaking existing implementations.

Can you give me an example of a default method?

Sure! Here's an example:

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

How do default methods affect interface inheritance?

Default methods allow a class to inherit behavior from an interface without needing to implement the method. This helps in maintaining backward compatibility.

Are there any limitations to default methods?

Yes, default methods cannot be static or private, and if a class implements multiple interfaces with the same default method, it must override it to avoid ambiguity.
