State Pattern – Design Patterns in Practice (2015)

This repository contains a simple and functional implementation of the State Pattern, one of the classic design patterns in software engineering.

It is intended as an educational example to help developers understand how to separate state-specific logic and transition handling in a clean, maintainable way.


🎯 Purpose

To demonstrate how the State Pattern can be implemented to manage behavior changes in objects based on their current state, without using large conditional statements.


📚 What is the State Pattern?

The State Pattern is a behavioral design pattern that allows an object to alter its behavior when its internal state changes. The object will appear to change its class at runtime.

Key benefits:

  • Eliminates complex conditional logic.
  • Encapsulates state-specific behavior.
  • Makes the code easier to maintain and extend.

⚙️ Technologies used

  • Java.
  • Object-Oriented Programming (OOP).
  • State Design Pattern.

🧪 Features demonstrated

  • ✅ Implementation of the State Pattern in Java.
  • ✅ Encapsulation of state-specific behavior.
  • ✅ Clean separation of concerns.
  • ✅ Easy to extend with new states.
  • ✅ Minimal, easy-to-follow example for learning purposes.

📄 Educational presentation

This repository includes a full presentation in PDF format explaining the State Pattern in detail, covering:

  • Definition and classification.
  • Purpose and motivation.
  • Applicability scenarios.
  • Structure diagrams.
  • Participants and collaborations.
  • Advantages and disadvantages.
  • Related patterns and bibliography.
