Example Of Inheritance

Learn how to use inheritance in Java to create a new class from an existing class. See examples of single, multilevel and hierarchical inheritance, method overriding, super keyword and protected members.

Inheritance is a mechanism in which one class acquires the property of another class. For example, a child inherits the traits of hisher parents. With inheritance, we can reuse the fields and methods of the existing class. Hence, inheritance facilitates Reusability and is an important concept of OOPs.

We group the quotinheritance conceptquot into two categories subclass child - the class that inherits from another class superclass parent - the class being inherited from To inherit from a class, use the extends keyword. In the example below, the Car class subclass inherits the attributes and methods from the Vehicle class superclass

Explanation In the above example, when an object of MountainBike class is created, a copy of all methods and fields of the superclass acquires memory in this object. That is why by using the object of the subclass we can also access the members of a superclass.. Note During inheritance only the object of the subclass is created, not the superclass. . For more, refer to Java Object Creation

Java Inheritance Example. Following is an example demonstrating Java inheritance. In this example, you can observe two classes namely Calculation and My_Calculation. Using extends keyword, the My_Calculation inherits the methods addition and Subtraction of Calculation class.

The above example code Employee and Manager is an example of single inheritance. Single Inheritance. 3.2. Multi-level Inheritance. In multilevel inheritance, there will be inheritance between more than three classes in such a way that a child class will act as the parent class for another child class. Let's understand with a diagram.

Java inheritance examples To help you understand inheritance more, let's look at Java inheritance examples in pseudocode. Pay attention to the syntax components of inheritance we've seen so far, like super and shared methods. To declare inheritance in Java, we simply add extends superclass after the subclass's identifier.

Inheritance Realtime Example. In the real world, a child inherits the features of its parents, such as beauty of mother and the intelligence of father, as shown in the below figure. Inheritance represents the IS-A relationship, also known as a parent-child relationship.

Inheritance is one of the core features of object-oriented programming.It's a programming procedure that allows you to reuse code by referencing the behaviors and data of an object.In other words, a class that inherits from another class shares all the attributes and methods of the referenced class.. An inherited class is called a subclass or child class of the class it inherits from.

7. Real-World Examples of Inheritance Example 1 Vehicle Hierarchy. Consider a vehicle hierarchy where Vehicle is the base class.Car and Bike can be derived classes that inherit properties and methods from Vehicle.. Example 2 Employee Hierarchy. In an employee management system, Employee can be the base class.Manager and Developer can be derived classes that inherit from Employee.
