Suggestion on example in Part1-4

Has a repeat for an example on what variable names should/shouldn't look like.

int 7variable = 4; // Not Allowed!
int variable7 = 4; // Allowed, but not a descriptive variable name

is repeated twice, despite the paragraph talking about not naming variables using commands provided by Java instead. I replaced it with names System.out.print and System.out.println since those were the examples given. Though in reality, even if they were commands provided by Java, they still wouldn't work as variable names due to having periods in them. Maybe other commands or keywords would be a better example, i.e. new.
