Inheritance:When one object acquires all the properties and behaviors of a parent object, it is known as inheritance. It provides code reusability. It is used to achieve runtime polymorphism. The keyword used for inheritance isextendsas follows. class derived-class extends base-class { //methods...
8. What is inheritance in java? Inheritanceallows use of properties and methods of another class (Parent class), so you can reuse all methods and properties. 9.What is multiple inheritance? Answer: When child class can inherit from multiple parent classes.This mechanism is known as multiple in...
another object. Inheritance is the mechanism of code reuse. The object that is getting inherited is called the superclass and the object that inherits the superclass is called a subclass. We useextendskeyword in java to implement inheritance. Below is a simple example of inheritance in java. ...
We are the children of our parents and we carry some of their characteristics through genes. Similarly, when a child class access data members of a parent class then it is called Inheritance in Java. It develops an IS-A relationship. It is used to achieve runtime polymorphism. ...

Aggregation Example in Java For example consider two classesStudentclass andAddressclass. Every student has an address so the relationship between student and address is a Has-A relationship. But if you consider its vice versa then it would not make any sense as anAddressdoesn’t need to have...
