I don't think so: knowing what to do with your knowledge may give some power,
otherwise you just have to carry that knowledge around in your brain.

... and to prove that, I wrote some VB.NET code today.(there's a first time for everything).
@Jos surely there's an easier way for that problem?

Erm, I didn't mean to say that when you accidentally know something that you
*have* to exercise that knowledge. Some knowledge can better be forgotten ;-)

ps. you can also iterate from the right and stop when you hit a letter ...

Yeah I knew that, I just couldn't grasp the syntax for the for loop!!

I consider that a little plus on your side.

No need to, nobody is perfect. Case closed, this is a Java forum after all.

Coming back to the original question then, how would I get this duplicates Snipper to work for primitives as well?

import java.util.Arrays;
import java.util.Collection;
import java.util.HashSet;
public class  Snipper<E> {
    E[] array;
    public static void main(String[] args) {
        Integer[] x = {4,4,7};
        System.out.println(Arrays.toString(new Snipper<Integer>().removeDups(x)));
    }
    public E[] removeDups(Object o) {
        Collection<E> c = null;
 
        if(o instanceof Collection) {
            c = (Collection<E>)o; 
        }
        else {
            try {
                array = (E[])o;
            }
            catch(ClassCastException cCE) {
                System.out.println("Not supported");
 
            }
        }
        if(c != null) {
            HashSet<E> s = new HashSet (c);
            array = (E[])s.toArray();
        }
        else if(array != null) {
            final HashSet<E> s = new HashSet () {
                {
                    for(E e : array) {
                        add(e);
                    }
                }
            };
            array = (E[])s.toArray();
        }
        return array;
    }
}

I didn't think you were going to use it because I thought you had an int[].
Which part do you not understand?
