![]() So, when we MainClass implements this interface, then there is no need to provide the implementation to show() method. As you can see it is not an abstract method, we are providing the implementation to it. ![]() In InterfaceWithDefaultMethod interface we are defining a default method show(). Implementing abstract method in seprate class Calling implemented method of same class ("Implementing abstract method in seprate class") Public class MainClass implements InterfaceWithDefaultMethod Syntax: To define a default method in the interface, we must use the “ default” keyword with the method signature. You can call a default method of the interface from the class that provides the The default methods in the interface are defined with the default keyword.Ģ. ![]() Now the developer can add new functionality to the interface by use of default method without breaking their existing implementation. Onward Java 8, You can declare the default methods and static methods in the interfaces. To resolve the issue, Java 8 introduced default methods and static methods in interfaces. If the programmer adds a new method to an interface, then the implementation of a new abstract method must be provided by the class which is implementing the interface. As we already know a separate class is used to provide the implementation of abstract methods. We have learned a lot of things about interfaces. Till java 7, Interfacescould have only abstract methods. ![]() How to achieve multiple inheritances by default methods? What is the default method in interface?ģ. Here is the table content of the article will we will cover this topic.ġ. ![]()
