Design Patterns
Strengthen your architecture skills with patterns
Apply Design Patterns
Design patterns provide proven solutions to recurring software design problems. In this section, you will apply the classic Gang of Four patterns to real-world scenarios, learning not just the structure of each pattern but also when and why to use them.
🏗️Creational Patterns in Practice
Work through exercises that require applying creational patterns like Singleton, Builder, Factory Method, and Abstract Factory. Build a multi-platform UI toolkit, design a flexible logging system, and construct complex objects with fluent APIs.
🧱Structural Patterns in Practice
Apply structural patterns including Adapter, Bridge, Composite, Decorator, and Facade to real-world problems. Integrate legacy systems, build extensible component hierarchies, add dynamic behavior without subclassing, and simplify complex subsystem interactions.
🔄Behavioral Patterns in Practice
Implement behavioral patterns such as Strategy, Observer, Iterator, and Interpreter. Design event-driven notification systems, build flexible algorithm selection mechanisms, create reusable traversal logic, and develop simple domain-specific languages.
