Where did the : come?

In for (char letter : mAnswer.toCharArray()) where did the : come from? This is really confusing I'm breaking my head on this one but its really hard to understand

That is an enhanced for loop, the : is just part of the syntax (you would normally say it out loud as in). So for your example, you would say it out loud as for each letter in answer.

See this SO answer to see the enhanced next to a normal for loop, they both do the same thing here: http://stackoverflow.com/a/11685345
