![]() You can use the same fields and methods already defined in the previous class. Reusability: As the name specifies, reusability is a mechanism which facilitates you to reuse the fields and methods of the existing class when you create a new class.It is also called a base class or a parent class. The Vehicle becomes the superclass of both Car and Sedan. Java Inheritance is transitive - so if Sedan extends Car and Car extends Vehicle, then Sedan is also inherited from the Vehicle class. Super Class/Parent Class: Superclass is the class from where a subclass inherits the features. Inheritance in Java is the method to create a hierarchy between classes by inheriting from other classes.It is also called a derived class, extended class, or child class. Sub Class/Child Class: Subclass is a class which inherits the other class.It is a template or blueprint from which objects are created. Class: A class is a group of objects which have common properties.For Method Overriding (so runtime polymorphism can be achieved).Inheritance represents the IS-A relationship which is also known as a parent-child relationship. Moreover, you can add new methods and fields in your current class also. When you inherit from an existing class, you can reuse methods and fields of the parent class. The idea behind inheritance in Java is that you can create new classes that are built upon existing classes. In the above section, we talked about bank accounts for minors and regular bank accounts (the ones owned by people aged 18 or over, without restrictions). With the use of inheritance, the information is made manageable in a hierarchical order. Inheritance can be defined as the process where one class acquires the properties (methods and fields) of another. Consider the following two examples: Example 1. Java Programming Java8 Java Technologies Object Oriented Programming. It is an important part of OOPs (Object Oriented programming system). You should use inheritance in Java if there is an is-a relationship between two classes. Inheritance in Java is a mechanism in which one object acquires all the properties and behaviors of a parent object. Why multiple inheritance is not possible in Java in case of class?. ![]()
