We can run abstract class in java like any other class if it has main() method. An interface in Java is defined as an abstract type that specifies class behavior. An interface is a kind of a protocol that sets up rules regarding how a particular class should behave. An interface in Java can contain abstract methods and static constants.

It can have abstract and non-abstract methods For example, the Shape class is used as a superclass for 2-dimensional We accomplish this in Java by defining the getArea method in the Shape class, but by Abstract classes let you define some behaviors; they force your subclasses to provide others. For example, if you have an application framework, an abstract class Similarly, other shape objects can be created by interface programming by implementing generic Shape Interface. Example 2: Below is a java interfaces program 17 Jun 2020 In Java, 'extends' keyword is used to show inheritance. Let us try to understand with the example of class Animal and class Cat.
