Java interface static method：Java 8 Interface Changes

Java 8 interface changes include static methods and default methods in interfaces. Prior to Java 8, we could have only method declarations in the interfaces. But from Java 8, we can have default methods and static methods in the interfaces.

Designing interfaces have always been a tough job because if we want to add additional methods in the interfaces, it will require change in all the implementing classes. As interface grows old, the number of classes implementing it might grow to an extent that it’s not possible to extend interfaces. That’s why when designing an application, most of the frameworks provide a base implementation class and then we extend it and override methods that are applicable for our application. Let’s look into the default interface methods and static interface methods and the reasoning of their introduction in Java 8 interface changes.

For creating a default method in java interface, we need to use “default” keyword with the method signature. ...
