The State Pattern

· Java Zone

Learn more about the advantages of moving from a monolithic to microservices architecture.  Brought to you in partnership with IBM.

Description:

The State pattern allows an object to alter its behavior when its internal state changes

Benefits:

  • Localizes state-specific behavior and partitions behavior for different states
  • Makes state transitions explicit

When to use:

  • An object’s behavior depends on its state, and it must change its behavior at run-time depending on that state.
  • Operations have large, multipart conditional statements thatdepend on the object’s state.
