What are the key differences between design patterns and anti-patterns in Java?

Design patterns are best practices for solving common problems in software design, while anti-patterns are common responses to problems that are ineffective.

Can you give me examples of both?

Sure! An example of a design pattern is the Singleton pattern, which ensures a class has only one instance. An anti-pattern example is the Spaghetti Code, which is tangled and difficult to maintain.

How do I decide when to use a design pattern?

You should consider using a design pattern when you encounter a recurring problem that has a proven solution, and when it improves code maintainability and readability.

What are some common anti-patterns I should avoid?

Some common anti-patterns include God Object, which centralizes too much functionality in one class, and Magic Numbers, which uses unexplained constants in code.
