Answer 1

Another thing :
int y = y + row * boxHeight;is not a valid code, because y has not been
initialized yet
write it in two lines, first declare, second use...Simply doing that won't help: int y;
y = y + row * boxHeight Still not initialized before use.
Presumably the y + should just be nixed, but I haven't looked closely enough at the code to see what he's really after.
