Polymorphism
One into many forms is the concept of polymorphism.
example 1: - method name is same but we can apply for different types arguments(Overloading).
public void m1(int) (Overloading)
public void m1(long) (Overloading)
public void m1(float) (Overloading)
example 2: - method signature is same but in parent class one type of implementation and in the child class another type of implementation(Overriding).
class Parent
{
public void m1()
{
System.out.println("Parent class method implemtation");
}
}
class Child extends Parent
{
public void m1()
{
System.out.println("Child class method implemtation");
}
}
example 3:- Using of parent reference to hold child object is the concept of polymorphism.
In Collection Framework List interface reference can be used to hold its child classes object like ArrayList, LinkedList, Vector, Stack.
