You could easily answer these by writing code and checking the results.

Sadly, I would have to enter way too much code to understand it. (Just this one won't be enough and it will give either an empty result or an error)..

I do have a lot of other things to study for. Thank you for the suggestion, but I would love if someone can help me out on this one.

As others said, you're better off writing the code yourself. Stackoverflow and Javadocs are pretty helpful too.
