While we are more than willing to help those that are stuck, that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.
So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.
And looking at your code, you haven't done anything much at all. Your methods are useless because they only work with local variables that are discarded when the method exits, and they don't use the value you pass to them at all - but that's ok because you don't assign it a value before you call the methods anyway!
To be honest, that looks like you threw some code at your screen without thinking about what you were trying to do at all, and hoped that either it would magically work or someone else would re-write it for you so it did
Neither of those things is likely to happen. Ever.
