The “dependency injection” (DI) technique is a way to improve testability and maintainability of object-oriented code. Typically adoption of dependency injection is coupled with adoption of a dependency injection framework, such as Guice  or Spring . These materials show how dependency injection can be accomplished without any framework. The same benefits provided by frameworks can be realized using “do-it-yourself” (DIY) handcrafted code. This model is named DIY-DI, pronounced die-die.
Update (May 29, 2010): I added a comparison with Guice and more polished code snippets to the DIY-DI manual.
