Inheritance in javais a mechanism in which one object acquires all the properties and behaviors of parent object. Types of Inheritance 1- single 2- multilevel 3- hierarchical Note: Java does not support multiple inheritance // Example of Inheritance package programs; class emp{ int sal=1000; }...
We can’t achieve multiple inheritances in Java through the class. It gives a compile-time error. Let me explain to you why! suppose there is a child class C and it extends class A & class B. In this scenario, suppose A & B classes have the method with the same name and child cl...
In the Java programming language, each class is allowed to have one direct superclass, and each superclass has the potential for an unlimited number of subclasses: A hierarchy of bicycle classes. The syntax for creating a subclass is simple. At the beginning of your class declaration, use ...

InheritanceSummary: Inheritance is a distinguishing feature of object-oriented programming languages, but its application in practice remains poorly understood. Programmers employ inheritance for a number of different purposes: to provide subtyping, to reuse code, to allow subclasses to customise super...
property from other objects. In Java, inheritance is defined in terms of superclass and subclass. it is normally used when some object wants to use an existing feature of some class and also wants to provide some special feature, so we can say inheritance has given the advantage of ...

Extends in Java is used for class inheritance, allowing a class to inherit properties from another class. Implements in Java is used by a class to adhere to an interface, defining specific methods.
In fact, if you look at the Java API libraries you will see many examples of inheritance. Every class in the APIs is inherited from a class called java.lang.Object. For example, any time you use a JFrame object, you're at the end of a long line of inheritance: java.lang.Object ex...
