Object Oriented Programming Abstract Class


Abstract classes and methods in object oriented programming.

Object oriented programming abstract class. Objects or classes may be abstracted which means that they are summarized into characteristics that are relevant to the current programs operation. That enables the user to implement more complex logic on top of the provided abstraction without understanding or even thinking about all the hidden complexity. An abstract class can only be used as the base class for some other class that is why it is impossible to create an object of the abstract class type. Abstract class is a class which cant be initiated which means they are considered as incomplete classes.

Most of the popular modern object oriented programming languages like java and c are class based. Because they are incomplete classes they can be called directly or cant be instantiated. These distinct concepts are. Classes are an abstract representation of real world objects.

By dharani prasanna ibm india. Classes which contain one or more abstract methods or abstract properties such methods or properties do not provide implementation. Abstraction is one of the key concepts of object oriented programming oop languages. In programming languages an abstract class is a generic class or type of object used as a basis for creating specific objects that conform to its protocol or the set of operations it supports.

Then why do we even need these. Its main goal is to handle complexity by hiding unnecessary details from the user. In object oriented programming a class is an extensible program code template for creating objects providing initial values for state member variables and implementations of behavior member functions or methods. They achieve the object oriented concepts such as encapsulation inheritance and polymorphism through the use of classes.

Abstract classes are used for creating generic entities that you expect to use for creating more specific derived classes. In many languages the class name is used as the name for the class the template itself the name for the default constructor of the class a subroutine that creates objects and as the type of objects generated by instantiating the class.
