Any javadoc class documentation is next. The class is last. 2.6 - Maximum Line Length Do not make lines longer than 120 characters. Most of your code should be under 80 characters per line. If your code starts to get indented way to the right, consider breaking your code into more methods.
Longer lines can be frustrating to work with.
2.7 - Parentheses Parentheses should be used in expressions not only to specify order of precedence, but also to help simplify the expression. When in doubt, parenthesize. No underscores, dollar signs or non-ascii characters. Hungarian Notation violates OO abstraction and is not to be used. All class and interface identifiers will use mixed case.
