Hint: highlight the "void" keyword in your code, then hit CTRL+SHIFT+F to access the Processing reference.

Well, try to follow the flow of code step by step.
First the declaration and init of the variable.
Then the call of draw() by Processing itself.
Which will call the function. Hint: the function appears to do something, but actually does nothing! Do you see why? Second hint: it is related to scope of variables...
After the function returns, the print will be called. What will it display?
