I'm in an accelerated java programming class for a job, and I'm falling behind. It's been almost 2 weeks and we are already finished with Java 1. I still have homework to turn in from previous chapters, but I'm completely lost as to how to do it. I've read this chapter about Arrays and ArrayList several times, but I'm still not understanding how to do this. Attached are two of my homework questions that I can't seem to figure out. Any help would be greatly appreciated!
