Example 1: Java Inheritance class Animal { // field and method of the parent class String name; public void eat() { System.out.println("I can eat"); } } // inherit from Animal class Dog extends Animal { // new
Inmultilevel inheritance, a parent class becomes the child class of another class. In the following diagram: class B is a parent class of C, however it is also a child class of A. In this type of inheritance, there is a concept of intermediate class, here class B is an intermediate c...
Inheritance is a mechanism that allows the class to use the states and behavior of another class. In simple words a class derive field and methods from another class. The derived class in inheritance is called sub class (also called derived class or extended class, or child class) and the ...
1. What is inheritance in Java? Inheritance in Java is a mechanism where a subclass derives properties and behaviors from a parent class, allowing for code reuse and hierarchical structuring. You can read more about inheritance in this tutorial onInheritance in Java. 2. What are the types of ...
In multilevel inheritance, there will beinheritance between more than three classesin such a way that a child class will act as the parent class for another child class. Let’s understand with a diagram. Multilevel Inheritance In the above example, Class B extends class A, so class B is ...
The benefit of interface is itallows multiple inheritancethat thing is not possible with concrete classes and abstract classes. With interfaces, implements keyword is to be used for implementing. Implements tells the compiler that whatever classes are there after implementation, they are interfaces. ...
Java instanceof during Inheritance We can use theinstanceofoperator to check if objects of the subclass is also an instance of the superclass. For example, // Java Program to check if an object of the subclass// is also an instance of the superclass// superclassclassAnimal{ ...

Inheritance is a mechanism of creating a new class from an existing class by inheriting the features of existing class and adding additional features of its own. When a class is derived from an existing class, all the members of the superclass are automatically inherited in the subclass. Howev...
