PCPP2 Design Patterns Practice Question
You are designing a State pattern. Which component is responsible for changing the state of the context object?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The concrete state objects
Either the Context or the State objects themselves can transition the state, but encapsulating the transition logic inside the concrete state objects is typical for complex state flows.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The abstract state base class
Why it's wrong here
The base class defines the interface, not the logic for transitions.
- ✗
A separate controller object
Why it's wrong here
This would violate the encapsulation of the state machine logic.
- ✗
The client code
Why it's wrong here
The client should ideally interact with the context, not manually transition internal states.
- ✓
The concrete state objects
Why this is correct
Concrete states often define the next state transition, keeping the context clean.
