20 Simple T/F Java questions. $5 reward.

EDIT:UPDATE: CASE CLOSED.
I got all the answers from an another source.
Thanks for your input anyways~


Below are sample T/F questions for my final exam. The only problem is that answers are not given. I wish I had time to go through books looking for answers but I'm pretty much out of time. I know $5 for these questions are lame but I thought it'd be better than nothing.

The answer you are probably going to get from people even in the know is "you should have allocated your time better" and I agree... Do the freakin' work. I mean if you can't figure out t/f questions, that's kind sad :/

edit: I'm not criticizing your post just saying you're probably wasting your money..

I agree with what you're saying as I had been one of those who said "Do the work own your own."
However, this time, I'm the one who has to say "If you can't help, keep it quiet."
