I need a method to compare two HashMap<String, ArrayList<String>>. Google Guava API has a Method but it is for single values only - http://docs.guava-libraries.googlecode.com/git-history/v9.0/javadoc/com/google/common/collect/package-frame.html. Perhaps someone already has the solution or a reference to an online resource that covers this?

Thanks

And how would you compare two of such maps? When are they equal? If you can describe it, you can easily compare the two by creating your own Comparator.
