First, a bit of business: you may not have read our naming policy on the way in. It requires that you use a full, real (sounding) first and last name for your display name. A single name isn't enough. You can change your display name here. Thanks!
Second, please don't post the same question to multiple forums.
Third, this has nothing to do with threads (so I deleted the copy in Threads) and nothing to do with SCJP, so I'm going to move this copy to the "Java in General (Beginner)" forum.
