Got this idea from this previous question.

How to create a generic array in Java?

Anyway, my code is like this:

public class Slice<E>
{
    private E[] data;
    public Slice(Class<E> elementType, int size)
    {
        //@SuppresWarnings({"unchecked"})
        data = (E[])Array.newInstance(elementType, size);
    }

}

I deleted the unnecessary stuff. This compiles fine when the suppress directive is commented out. When I uncomment it, I get 

Error: <identifier> expected    
        data = (E[])Array.newInstance(elementType, size);
             ^

Any ideas? why would this be happening?

You cannot put an annotation there. It must go before the public keyword. And you've mistyped the annotation name as well: change SuppresWarnings to SuppressWarnings.

EDIT: If you were using an IDE like Eclipse, you would typically use the auto-correction feature to insert the annotation. Naturally, it would be inserted in the right place and correctly spelled.

Long time no java for me, but you'd put that on the method, not just inside it somewhere, right?

  • In the other thread, they have it on the method like you're suggesting. I just tried that right now, and got this error: cannot find symbol symbol : class SuppresWarnings location: class Slice @SuppresWarnings({"unchecked"}) ^ – Derrick Aug 13 '09 at 02:29
  • Yeah, so you'll need to find the package that that class is in and import it. – Noon Silk Aug 13 '09 at 02:32
  • @silky: no ... he'll just need to spell the annotation class name correctly :-) – Stephen C Aug 13 '09 at 02:48
  • Yeah, I noticed this seconds after posting because I scrolled to see your answer :) – Noon Silk Aug 13 '09 at 02:49
