Real-World Analogy of State Design Pattern
Imagine a traffic light as a robot. It has different moods like “Stop” (Red), “Get Ready” (Yellow), and “Go” (Green).
- The robot changes its mood based on the time or if cars are waiting.
- When it’s “Stop”, cars stop, and people can walk. When it’s “Get Ready”, it’s about to change. And when it’s “Go”, cars can drive.
- This setup makes it easy to add new moods or change how the robot behaves without messing up everything else. So, it’s like having a robot traffic light that knows when to stop, get ready, or go!
State Design Pattern
The State design pattern is a behavioral software design pattern that allows an object to alter its behavior when its internal state changes. It achieves this by encapsulating the object’s behavior within different state objects, and the object itself dynamically switches between these state objects depending on its current state.
