Polymorphism means that if you have

class A {
void method1() {
// some stuff


class B extends A {

void method1(){
//anotyher stuff


now somewhere in you code you'll create instance

A  b = new B();

in this case //another stuff will be executed, not //some stuiff

this is callled polymorphism - when instance was created as subclass
and it excutes metyhod which is overriden in scbclass it will always
execute the stiff in the method of subclass, not in the method of class

let me know if there ias somethiong not clear about it
