Recently the Google Collections Library came to my attention. The Google Collections Library is a suite of new collections and collection-related goodness for Java 5.0, brought to you by Google.

Since I’m a frequent user of apaches’ commons-collections library I wondered what the difference is.

From browsing the API and FAQ it seems that:

• It fully based around Java5 features, which is a big issue of commons-collections
• Implementations adhere to the contracts specified by the JDK interfaces
• Almost all implementations are final, according to the FAQ extension should be done through decoration using the ‘forwarding collections’
• They haven’t done any my favorite ‘LazyXYZ’ implementions yet

From the looks of it I think we will see this nice library being adopted quite fast; I’ll certainly be using it on future Java projects. Maybe I’ll even write some ‘LazyXYZ’ decorators using the ‘forwarding collections’!
