What are some common design patterns in different programming languages?
Common design patterns include Singleton, Factory, and Observer. They can be implemented in various languages like Java, Python, and C#.
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.
How does the Factory pattern work?
The Factory pattern defines an interface for creating objects but allows subclasses to alter the type of objects that will be created.
Are there any specific languages where these patterns are particularly useful?
Yes, for example, the Singleton pattern is often used in Java for managing database connections, while the Factory pattern is popular in C# for creating UI components.
