Adhere to commonly used coding standards as set by Oracle, Eclipse, or Google. All major IDEs can format code according to the standards. Use "speaking" (i.e. self explanatory) names (variables, classes, and methods). Use constants (static final variables) instead of "Magic numbers". Whenever a number has a special meaning other than a simple counter, create a constant that explains the meaning of the number and use only the constant. Use comments to explain why something was coded in a certain way, not to explain how something was coded, or what the code does. Use JavaDoc to document your code. More on reddit.com
