Utilities, Singletons and Dependency Injection - Effective Java, Items 3-5

Want to play around with the code yourself? Check out the repository Effective Java, a code base with examples, tests, and benchmarks for my YouTube series on Effective Java, Third Edition - it contains many of the snippets shown in the video. It has a permissive license, so you can reuse the code for your projects.
