*sniff sniff* Smells like homework. We don't do homework here. If you bring
some code to us, we'll be happy to help you straighten it out and figure out
whatever problems you run into. That said, if you can figure it out on
paper, you should be able to code it. Just break it down into the simplest
steps you can. For example, the first thing you might notice is that you
have one set of conditions for n <= 5 and another for n > 5. That's an if
statement if I've ever seen one:
if (n <= 5) {
    ...
} else {
    ...
}

Or if you prefer:
if (n > 5) {
    ...
} else {
    ...
}

That's your first "rule" governing the problem. Just break it down more from
there and fill in what you need. See http://www.physci.org/codes/sscce.jsp
for tips on posting your code to the ng for help.

Finally, please post to comp.lang.java.help in the future. This group is
deprecated.
