What is Google Guice?

Google Guice is an open source software framework for the Java platform released by Google under an Apache license. It provides support for dependency injection using annotations to configure Java objects.[1] Dependency injection is a design pattern whose core principle is to separate behavior from dependency resolution.
Guice allows implementation classes to be programmatically bound to an interface, then injected into constructors, methods or fields using an @Inject annotation. When more than one implementation of the same interface is needed, the user can create custom annotations that identify an implementation, then use that annotation when injecting it.

Google Guice is a Dependency Injection Framework that can be used by Applications where Relation-ship/Dependency between Business Objects have to be maintained manually in the Application code. Since Guice support Java 5.0, it takes the benefit of Generics and Annotations thereby making the code type-safe.
