Hi Question

[Fred Man]

what is What is polymorphism and why is it important in Object Oriented programming.?

Please help

[Fred Man]

Also can you give example of code

[Gaurav Chhabras]

First of all please keep this thing in your mind that

Write some meaningful subject in the subject line so that one can see the subject and come to know that what type of question it contains

This is Ranch policy , so please follow this.

Now , regarding polymorphism, you can understand with the help of methord overriding. In this we have two different classes but some methords are with same name.

Like -:

class A
{
void test()
{
System.out.println("I am in Class A");
}
}

class B extends A
{
void test()
{
System.out.println("I am in Class B");
}
}

Now there are two classes A and B.Both have one function with same name i.e test(). Now at runtime it will depend on the Object that test() methord of which class will be get called.

Thanks
Regards
Gaurav
