实现这一点的最佳设计模式是什么？

$ b $我正在考虑将所有课程都创建为单身人士，但这将创造出许多单身人士。有很多单身吗？

解决方案

看看Steve Yegge关于这个的博客文章 - Singleton Consideed Stupid

I have a few classes in a project that should be created only once.

What is the best way to do that?,

1. They can be created as static object.
2. Can be created as singleton
3. Can be created as global.

What is the best design pattern to implement this?

I am thinking of creating all classes as singleton, but that would create lot of singletons. Is it good programming practice to have lot of singletons?

What are the pros and cons for using singletons?
