Homework - Using basic arrays in java

I'm working on learning some basic java programming. I have a project that I've been working on dealing mostly with arrays. I have completed the objective, I'm just not sure that I did it in the most effective way possible. My question here is to see if an experienced java programmer wants to take a crack at it so I can compare the coding.

I will include a link to the description of the project. Mind that I am not a student in this class, merely using the guidelines to learn the java language.

I would love any feedback I can get. Thanks!

As you already have been told at another place, post the code you have and we will try to help you to improve it.
