An abstract class serves as a basis for a group of related subclasses. It forms the abstractions that are common to all subclasses by specifying the common properties and methods that all subclasses must implement.

The abstract class can not be instantiate. 

Abstract classes are useful for describing functionality that is common to a group of classes, but requires unique implementations within each class. This approach is often called an interface because the abstract class defines the interface of each subclass without specifying the actual implementation.

The basic idea of an interface class is to specify the properties and methods that each subclass must implement without defining the actual implementation. This approach enables you to enforce a consistent interface to a group of related objects. As you add more classes in the future, the original interface remain.
