Abstract classes are classes that contain one or more abstract methods. Abstract method is a method that is declared, but contains no implementation. Abstract classes may not be instantiated, and require subclasses to provide implementations for the abstract methods.

An abstract class is a template definition of methods and variables of a class (category of objects) that contains one or more abstracted methods. ... Declaring a class as abstract means that it cannot be directly instantiated, which means that an object cannot be created from it.

Abstract class is the class designed for inheritance, for which no object will be created in the programming, but objects created for those classes that are inherit functions, methods from objects of classes those inherited. For example class A is a abstract class ,class B inherits A, objects of class B can be created but not A. These objects use the methods of A also B.
