The previous example is overloading not polymorphism.

Polymorphism is multiple classes having the same method -
for example - a DOG and CAT class that are sub classes of
ANIMAL - ANIMAL has a virtual function - SPEAK. DOG
implements speak via System.out.println("WOOF") and CAT
implements it as System.out.println("MEOW") then

ANIMAL anim = null;
anim = New DOG();
anim.speak();
anim = New CAT();
anim.speak()

will each put out the appropriate string.
