May I suggest you take a look at Use a Meaningful Subject Line? Having the comment that you are close to submitting in the subject line does not help explain what the topic is about, and in fact may induce some people to skip your post if they cant be bothered working out what the subject is about.
I would suggest you look at the javadoc that is provided for the J2SE API. From a single page, I can see every package and every class. I can then narrow it down as desired.
