Polymorphism means many forms.
A single object can refer to the superclass or subclass depending on the reference type which is called polymorphism.
Example:
public class Manipulation{
//Super class
public void add(){
}
}
public class Addition extends Manipulation(){
// Sub class
public void add(){
}
public static void main(String args[]){
//Manipulation is reference type and Addition is reference type
Manipulation addition = new Addition();
addition.add();
}
}
Using Manipulation reference type we can call the Addition class “add()” method. This ability is known as Polymorphism.
Polymorphism is applicable for overriding and not for overloading.
