It allows a class to use the properties and methods of another class. C++ Object Oriented Programming Programming. Public static final int noOfWheels= 4 //constantĪvailable here System.out. Inheritance is one of the useful feature of OOPs. In java above can be implemented like this: class FourWheeler This way the level of hierarchy can be extended to any level.

Car acquires these properties from FourWheeler, and has some specific properties, which are different from other classifications of Four Wheeler, such as luxury, comfort, shape, size, usage etc.Ī Car class can have further sub classes such as an OpenCar, Hatchback, Sedan, SUV, etc, which will acquire the properties from both Four Wheeler and Car, but will still have some specific properties. Inheritance in Object Oriented Programming (OOPS) Inheritance: An Idea of Code Reusability in OOPS What is Inheritance in OOPS Inheritance is a core principle of object-oriented programming (OOP) that allows us to derive a class from another class or a hierarchy of classes that share a set of attributes and methods. An implementation of composition over inheritance typically.

FourWheeler class defines vehicles that have four wheels, and specific range of engine power, load carrying capacity etc. This is an often-stated principle of OOP, such as in the influential book Design Patterns (1994). Other sub classes could be a Jeep, Tempo, Van etc.

When one class inherits from another, the inheriting class is known as a. Here Car acquires the properties of the FourWheeler class. A class can inherit methods, properties, and other characteristics from another class. The inheritance concept is very useful for reusability.įor example: Car is a sub class of FourWheeler class. Inheritance is the process of acquiring the properties of the base class into the sub class.
