Codelab is very specific

In codelab today I met my coding partner and he seems pretty cool. He has coded a little in the past but never in Java, so we are about on the same level. We started coding the first few problems and they seemed easy. There were some times when the code was denied because of insufficient spacing in strings, which is sometimes hard to tell. In one instance there was suppose to be a println at the end of the code but we only had a print statement. It was hard to notice that this was an error because it is difficult to see a new line that is at the end of code. Eitherway we figured out how to do all the problems and I am getting a feel for some of the simple mistakes to be wary of when coding.
