What is meant by Abstract class?

Question

Shrikant Mishra · Answer

We can create the Abstract class by using the “Abstract” keyword before the class name. An abstract class can have both “Abstract” methods and “Non-abstract” methods that are a concrete class.

Abstract method :

The method which has only the declaration and not the implementation is called the abstract method and it has the keyword called “abstract”. Declarations are the ends with a semicolon.

Example:



1

public abstract class Manupulation{

2

public abstract void add();//Abstract method declaration

3

Public void subtract(){

4

}

5

}

An abstract class may have a Non- abstract method also.

The concrete Subclass which extends the Abstract class should provide the implementation for abstract methods.
