Your fist step is to figure out how you would do it "manually." What information do you need to keep track of? What operations do you need to perform? What decisions do you make? Describe the steps as precisely, thoroughly, and simply as possible, without regard to Java or computers--just as a general set of instructions. Once you have that, if you've done it correctly, translating it to Java will be relatively easy.

I can't help you unless you show some effort and ask a more detailed question. What did you try? Where did you get stuck?

Only keep your codes inside your CodeTags for better readability..

By overriding Comparator OR Comparable interfaces methods you can achieve sorting your collection.Google the interfaces.
