				<font face="Times New Roman" size="4">

	If subclass (child class) has the same method as declared in the parent class, it is known as
	method overriding in java.
	In other words, If subclass provides the specific implementation of the method that has been
	provided by one of its parent class, it is known as method overriding.
	Usage of Java Method Overriding
	•	Method overriding is used to provide specific implementation of a method that is already
	provided by its super class.
	•	Method overriding is used for runtime polymorphism
	Rules for Java Method Overriding
	1.	method must have same name as in the parent class
	2.	method must have same parameter as in the parent class.
	3.	must be IS-A relationship (inheritance).
