Dude,

your code examples are poorly formatted (if at all), your questions are out in left field, and it appears you haven't tried to implement any of the code and try it out for yourself....

Get an intro Java book, and do some Homework.

Cheers.

Since that is obviously a homework or course question, we expect you to provide what you think the answer is. Bert Wilkinson is correct.
