What Is Implementing Interface In Java at Amelie Monk blog

What Is Implementing Interface In Java. The interface in java is a mechanism to achieve abstraction. An interface, in the context of java, is a completely abstract reference type that contains constants, abstract methods, default methods, static methods, and nested types. Like abstract classes, we cannot create objects of interfaces. An interface can only have method signatures, fields and default methods. In the next block you can see an example of interface: Interface methods are by default abstract and public. There can be only abstract methods in the java interface, not method body. It is used to achieve abstraction. An interface in java programming language is defined as an abstract type used to specify the behavior of a class. On implementation of an interface, you must override all of its methods. To use an interface, other classes must implement it. To declare a class that implements an interface, you include an implements clause in the class declaration. Since java 8, you can also create default methods. Interface in java is a bit like the class, but with a significant difference:
