  • All member variables are private. From the outside, you access everything via methods.
  • The constructor is always named “initialize” instead of the name of the class.
  • You have “mixin’s” instead of interfaces.
  • YAML tends to be favored over XML.
  • == and equals() are handled differently in Ruby. Use == when you want to test equivalence in Ruby (equals() is Java). Use equal?() when you want to know if two objects are the same (== in Java).
