Using the Scala collections (immutable) from Java

原文 2013-07-17 13:45:41 1 1 java/ scala-collections

Is it possible to use the Scala immutable collections (HashMap, List, Vector, etc.) from Java code? I realize that some of the method names may end up looking "funny" and contain "$".

I have a legacy application written in Java. I cannot convert the code at this time, but I would like to use the immutable data structures to improve concurrency (multiple reads for every write).

Yes, you just need to put scala-library.jar in the classpath. See this thread for an example using Scala immutable lists in Java

As an alternative, Clojure also offers persistent data structures eg a PersistentHashMap that come with Java source code, so your method names won't look as odd
