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.
