Handling exception in overridden class

Code :

---

 
import java.io.*;
class A
{
    public void display()
    {
        System.out.println("SuperClass");
    }
}
public class B extends A 
{
   @Override
       public void display() throws IOException
       {
           System.out.println("SubClass");
       }
}

---

Here, A is base class and B is derived class.
Now if method display() in class B throws IOException, it gives compile error.
It says, overridden method does not throw java.io.IOException. What does that mean?
But if it throws any other exception like ArithmeticException or NullPointerException, it works fine.
So, what is the problem??
Plzzz help.

You are trying to change the definition of the method.

You have left off part of the error message. Please post the full text of the error message.

Please write with proper grammar. Your post is virtually unreadable...'U' and 'plz' are not words
