Getting rid of unchecked operations related to Vector class

[Tobie Henderson]

Hey, I am writing a class called Pair which extends the Vector class. The constructor and add methods are the same as the Vector class. So I can create a new Pair object by:

Pair pair = new Pair();

Now, I want to add objects of another user-defined class called Player to this Pair object.

pair.add(player); //player is an instance of Player class

This is a problem, because it gives me "unchecked operation" errors because the raw type of Vector is not matching. How do I get rid of them? Do I have to override the constructor or the add method of the Vector class in a particular fashion to get rid of this error?

FWIW, I solved the problem. I just changed the class definition of Pair to which was previously:

public class Pair extends java.util.Vector {

to:

public class Pair<Player> extends java.util.Vector<Player> {

so that it can handle Player objects. Then I create a new Pair object by saying:

Pair<Player> pair = new Pair<Player>();

That's it.
