Blank Lines
Blank lines are used to delineate different areas of the code. The
instance variable declarations at the top of your program should be
separated from the header of the class and the header of the first
method. There should always be space between methods. It is
advisable to break up long method bodies and long declarations into
logical pieces. Always start a new line after the semicolon.
Always leave a blank line before a comment line.
