However the interface offers full abstraction in java something that abstract classes cannot do. By watching this tutorial you can understand about all the differences between interfaces and abstract classes in java programming language by the help of real life examples and programs. 1 an abstract class can extend only one class or one abstract class at a time an interface can extend any number of interfaces at a time. Another way of achieving abstraction in java is by using interfaces.

An abstract class can extend another java class and implement multiple java interfaces. But unlike abstract class an interface provides full abstraction in java. Interface supports multiple inheritance. Interface can have only abstract methods.

Abstract class interface and their difference. A class can extend only one abstract class while a class can implement multiple interfaces. Sample code for interface and abstract class in java. Since java 8 it.
