What are some other design patterns in Java?

In addition to the commonly known Singleton and Factory patterns, Java also supports patterns like Observer, Strategy, and Decorator.

Can you explain the Observer pattern?

Sure! The Observer pattern allows an object, known as the subject, to maintain a list of dependents, called observers, and notify them of state changes.

What is the use case for the Strategy pattern?

The Strategy pattern is useful when you want to define a family of algorithms, encapsulate each one, and make them interchangeable.

How does the Decorator pattern work?

The Decorator pattern allows behavior to be added to individual objects, either statically or dynamically, without affecting the behavior of other objects from the same class.
