  • Proxy – Wraps an object to control access to it
  • Factory Method – Subclasses decide which concrete classes to create
  • Adapter – Wraps an object an provides a different interface to it
  • Observer – Allows objects to be notified when state changes
  • Template Method – Subclasses decide how to implement steps in an algorithm
