And so, armed with their newfound knowledge, the Code Crusaders returned home, ready to tackle the challenges of software development with the power of design patterns at their side.

public class AnimalFactory { public static Animal createAnimal(String type) { if (type.equals("dog")) { return new Dog(); } else { // ... } } } As they journeyed on, the Code Crusaders entered the territory. They met the Adapter, a clever pattern that enabled them to use existing classes with incompatible interfaces. The crusaders learned to adapt and reuse code, reducing duplication and improving modularity. They met the Adapter, a clever pattern that
