First figure out an algorithm: how would you solve this problem just using pencil and paper. Once you know your equations and steps to take, then translate to Java. Why not give it a try first? You can't break your computer by doing this. Then come back with your code if you are still stuck.
Good luck.galaxyboy25,
This is very good advice. Getting into the habit of working out problems on paper/whiteboard first will save you many a headache later on. I'm relatively new to programming as well (only about 2 years professional experience) but this technique has helped me immensely in my work. In my mind, writing code is easy--figuring out what to write is where the real challenge is.
One other thing. In addition to sketching your problem on paper, it always helps to break a problem into very small, simple, and easily solvable pieces. Then put them together. In doing this you will find that not only will this make your task of problem solving much easier but you also end up writing cleaner and more flexible code.
