What are some of the best design patterns for beginners?

Some great design patterns for beginners include Singleton, Factory, and Observer patterns. Would you like to know more about any specific one?

Can you explain the Singleton pattern?

Sure! The Singleton pattern ensures that a class has only one instance and provides a global point of access to it. It's useful when exactly one object is needed to coordinate actions across the system.

What about the Factory pattern?

The Factory pattern is a creational pattern that provides an interface for creating objects in a superclass but allows subclasses to alter the type of objects that will be created.

How do I implement the Observer pattern?

To implement the Observer pattern, you create a subject that maintains a list of observers and notifies them of any state changes. This is useful for implementing distributed event handling.
