What are some common design patterns in software development?

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

Can you explain the Singleton pattern?

The Singleton pattern ensures a class has only one instance and provides a global point of access to it. It's useful for managing shared resources.

What about the Observer pattern?

The Observer pattern defines a one-to-many dependency between objects, so when one object changes state, all its dependents are notified. It's great for event handling.

Can you give an example of the Factory pattern?

Sure! The Factory pattern creates objects without specifying the exact class of object that will be created. For instance, a ShapeFactory can create different shapes like Circle or Square based on input.
