when i try to compile the following code as part of a servlet application , the following Xlint:unchecked error occurs.I cant understand since I am using jdk1.5 or is it referring to generics in collections?if so could anyone pls reply how to fix it(inc any code help).Thanks in advance.

import java.util.*;

public class BeerExpert{
public List getBrands(String color) {
List brands = new ArrayList();

brands.add("Jack Amber");
brands.add("Red Moose");
brands.add("Jail Pale Aile");
return (brands);


Note: uses unchecked or unsafe operations.

If you're studying for SCWCD, you'd better use sdk1.4 instead.
That would spare you some time resolving that kind of problems.
