Compare values in an ArrayList to another int variable

Question

Hi all i'm just starting to use and understand ArrayList's, however i've come upon a problem and am a bit stuck! I want to compare an int variable, say int num to the values in an arrayList to see if the arrayList contains a match to num. I've looked through several tutorials and haven't found anything that talks about this, so is it possible and if so how?

@Keith: Hey, I was only reading the question ;)!
is there a way of adding multiple ints to an array list in one statementAdding to a list, not creating one...
@OP: Run this. And weep. (Or, at least be aware of the problem.)
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
public class AddAllEg {
    public static void main(String[] args) {
        test1();
        test2();
    public static void test1() {
        List<Integer> list = new ArrayList<Integer>();
        list.addAll(Arrays.asList(1, 42, -1));
        System.out.println(list);
            // later...
        list.add(0);
        System.out.println(list);
    public static void test2() {
        List<Integer> list = Arrays.asList(new Integer[] {1, 42, -1});
        System.out.println(list);
            // later...
        list.add(0);
        System.out.println(list);
}[Arrays.asList()|http://java.sun.com/javase/6/docs/api/java/util/Arrays.html#asList(T...)] does more than merely "make" a list.
