Guice is a lightweight dependency injection framework for Java.

Google Guice

Guice is Google's lightweight dependency injection framework. It is an open source software framework for the Java platform, compatible with Java 5 and above, released by Google under the Apache License.

It provides support for dependency injection using annotations to configure Java objects. 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.

Starting with version 3.0, Guice implements the JSR-330 standard of dependency injection for the Java platform.
