Chapter 4. The collective Groovy datatypes > Notes on Groovy collections

4.4. Notes on Groovy collections

The Java Collections API is the basis for all the nice support that Groovy gives you through lists and maps. In fact, Groovy not only uses the same abstractions, it even works on the very same classes that make up the Java Collections API.

This is exceptionally convenient for those who come from Java and already have a good understanding of it. If you haven’t, and you are interested in more background information, have a look at your Javadoc starting at java.util.Collection.
