I have mad a I/O program containing som methods that might throw
IOException. First time I made these methods I used "try/catch" staments to
catch and handle these exception.

But now I just tried to write "throws IOException" in the header line in
some of the methods and that also works!

I prefer the last kind of code because its more simple, is it just a matter
of choice what you do or are there some differences? It works either way
