Index

1. Avoid comments when possible; they are unnecessary and may potentially lie.
2. Use clear method (and variable) names, as long as necessary.
3. Break down long methods
5. Avoid secondary effects when possible; they obfuscate the code.
6. Use constants/enums instead of literals; they help maintainability.

Other stuff

1. Build Strings with String.format

• Most important:
  • F3 / Ctrl+click: Go to declaration.
  • Ctrl+Alt+H: show all uses (calls) of a method.
  • Alt+Left: previous cursor position.
• Important:
  • F4: show Type Hierarchy.
  • Ctrl+O: search for method in class (great for navigating big classes).
• Others:
  • Ctrl+Shift+F: Format selection.
• Alt+Shift+A: Toggle block-editing mode.
