/*

* ------------ Inheritance --------------

* # use for code re-usability.

* # process of accessing properties and methods of parent/super/base class to child/sub/derived class is known as inheritance.

*

* # Also known as IS-A relationship(e.g car is a vehicle)

* # Its a generalization to specialization process.

* # we can't inherit a private variables, private method and constructors.

* # we can inherit static variables and methods.

* # "extebds" keyword is used to inherit.

* # we can inherit only one class at a time.

*

* syntax :

*

* class child_class_name extends parent_class_name {

*

* // properties : parent + child

*

* // method : parent + child

*

* }

*

* e.g

*

* class A {

*

* }

*

* class B entends A{

* // gets the properties and method ko class A

* }

*

* class C extends B {

*

* // gets the properties and method ko class B

* // and after the class B is extends to Class A then class c also gets the properties and method ko class A as well

*

* }

*

*

* -------------------- Method overloading in java ----------------------

*

* -> if a class have multiple methods by same name but different parameters, it is known as method overloading.

*

* e.g we have a method to sum(arg1, arg2) then it is only able to give sum of 2 number but for 3 number we have to make the another method havong same name i.e sum(arg1, arg2, arg3)

*

* it can be implemented by :

* 1> changing the data types

* 2> changing the arg size

*

*
