What are abstract classes? What are the distinct characteristics of an abstract class?

An abstract class is a class that cannot be instantiated and is always used as a base class.

The following are the characteristics of an abstract class:

You cannot instantiate an abstract class directly. This implies that you cannot make an object of the abstract class; it must be inherited.

You can have abstract as well as non-abstract members in an abstract class.

You must declare at least single abstract method in the abstract class.

An abstract class is always public.

An abstract class is declared using the abstract keyword.

The basic purpose of an abstract class is to give a common explanation of the base class that multiple derived classes can share.
