Ok would someone look at this code and please tell me what I need to do to make the program run correctly? It is supposed to give the user a message if they enter any money below 25 cents or over 100. And it's not doing what it's supposed to. Plus, I have no idea how to code the part about only taking multiples of five. I know there are some smart, smart
java guys out there that can help me. I'd appreciate anything you can tell me.
