Default Method In Java

Default methods are non-abstract methods in Java. We can create a default method in Java by simply adding the default keyword to the method signature and providing the default implementation that can be used, overridden, or ignored without causing problems for existing classes that have implemented an interface.

Introduction. Java 8 introduced static and default methods in interfaces, which were a major change to the language. Before Java 8, interfaces could only have abstract methods. With static and default methods, Java 8 allows interfaces to have concrete methods, enabling more flexibility and providing default functionality.
