The 9 Rules of Object Calisthenics

Object Calisthenics outlines 9 basic rules to apply when performing the exercise:

  • One level of indentation per method.
  • Don't use the ELSE keyword.
  • Wrap all primitives and Strings in classes.
  • First class collections.
  • One dot per line.
  • Don't abbreviate.
  • Keep all classes less than 50 lines.
  • No classes with more than two instance variables.
