It is declared by assigning a value of 0 to the declaration. For instance, What is an Abstract Class? In C++, an abstract class has at least one pure […]

The Java interface can only have abstract methods, no method bodies. In Java, it is used to achieve abstraction as well as multiple inheritance. Java Interface also represents the […]

Both abstract and non-abstract methods can be used (method with the body).Note: Abstraction is the process of hiding implementation details from the user and only displaying functionality. A class that is declared using the abstract keyword is known as an abstract class. Abstract classes […]
