what's the problem?

(sorry for my bad english)

Answer 1

Not an error in code. Code is fine. Problem would be in the input. No element exception would mean a value isn't being added to the list. Since most compilers will ask for input each time it's called, I have to assume you're trying to run the code in code playground? If that's the case, you'll need to input all 5 values in the first input box. It doesn't run like a normal program and request input everytime scanner.next is called. It will take all values at once, and put them in accordingly.

try nextLine. If I saw your add() method then maybe I could say what is wrong.
