This intermediate path begins with a review of core object-oriented programming concepts in Java, including encapsulation, inheritance, polymorphism, classes, and objects. These concepts provide the foundation for understanding how design patterns solve recurring software design problems.
You will explore creational, structural, and behavioral patterns such as Singleton, Factory Method, Builder, Adapter, Decorator, Composite, Observer, Strategy, and Command. Along the way, you will learn how these patterns support flexible object creation, composition, communication, and responsibility management.
You will then apply multiple patterns while developing a smart home system in Java. This project demonstrates how to select and combine patterns to create code that is maintainable, extensible, and suited to real-world requirements.
