Added Fortran

Fixed my compiler issue so that I could
test my code before pushing it.
Fixed comment typo & cleaned up code.

Removed System.exit(0);, it isn't needed at all, nor have I ever seen it used in hello world programs.

Removed /n from text and replaced print() with println(), same thing, just cleaner.
