abstract class code in oop
How do you code an abstract class?
An abstract class is a class that can only be subclassed--it cannot be instantiated.
To declare that your class is an abstract class, use the keyword abstract before the class keyword in your class declaration: abstract class Number { . . . }What is abstract class in OOP?
An abstract class is a template definition of methods and variables in a specific class, or category of objects.
In programming, objects are units of code, and each object is made into a generic class.
Abstract classes are classes that contain one or more abstracted behaviors or methods.What is abstraction code in OOP?
In object-oriented programming, abstraction is one of three central principles (along with encapsulation and inheritance).
Through the process of abstraction, a programmer hides all but the relevant data about an object in order to reduce complexity and increase efficiency.Abstract Class in Java does the process of hiding the intricate code implementation details from the user and just provides the user with the necessary information.
This phenomenon is called Data Abstraction in Object-Oriented Programming (Java).
