Read moreWhat does interface mean in OOP?
Interfaces allow you to specify what methods a class should implement . Interfaces make it easy to use a variety of different classes in the same way. When one or more classes use the same interface, it is referred to as “polymorphism”.
Read moreWhy do we use interfaces in programming?
Why do we use an Interface? It is used to achieve total abstraction . Since java does not support multiple inheritances in the case of class, by using an interface it can achieve multiple inheritances. It is also used to achieve loose coupling.
Read moreWhat is difference between interface and abstract class C++?
An “interface” embodies the concept of a contract between clients and an implementation. An “abstract class” contains code that you want to share between multiple implementations of an interface . While the interface is implied in an abstract classes methods, sometimes it is useful to specify the contract in isolation.12 Eki 2012

The short answer: An abstract class allows you to create functionality that subclasses can implement or override. An interface only allows you to define functionality, not implement it . And whereas a class can extend only one abstract class, it can take advantage of multiple interfaces.
Read moreHow do you create an abstract class in C++ program?
To be an abstract class, it must have a presence of at least one virtual class . We can use pointers and references to abstract class types. If we don’t override the virtual function in the derived class, then the derived class also becomes an abstract class. We can create constructors of an abstract class.2 Eyl 2021
