Generics and clone().

Question

I am trying to do
ArrayList<Integer> tempList = (ArrayList <Integer>) list.clone();but I get the unchecked warning. list is defined as ArrayList<Integer> list.
Basically, I am trying to cast the clone of list so that list remains unchanged by my method, so I am creating a templist using the clone. I am confused with respect to how to go about doing this cast using generics.
Thanks in advance.

This version gives the warning:
public class Test {
    public static void main(String[] arguments) {
        ArrayList<Integer> list = new ArrayList<Integer>();
        ArrayList<Integer> clone = (ArrayList<Integer>)list.clone();
}However, Drake_Dun is right, you probably want to copy the
list rather than cloning it. If you insist on using clone without a
warning, you loose the type information:
public class Test {
    public static void main(String[] arguments) {
        ArrayList<Integer> list = new ArrayList<Integer>();
        ArrayList<?> clone = (ArrayList<?>)list.clone();
}
