i still havent figured out how to solve the warning it gives. can someone esplain to me the warning and maybe you could teach me how to properly use collections.

If you have JDK 1.5 it is because you are not using Generics.

Read about Generics in the New Features portion of the Java SE 5 documentation on Sun.
