Use single letter identifiers only for the counter in loops. Multi-word identifiers are internally capitalized. Do not use hyphens or underscores to separate multi-word identifiers. Blank Spaces Use one blank space to separate classes and methods. Indent two spaces at a time.
Packages are all lower case.
Methods begin with a lower case letter. Multi-word identifiers are internally capitalized in methods. Each class should be contained in its own file. Each file should be named as the name of the class contained within it. Packages are preferred.
