Q.  Scala has many collection classes and it can also use the Java collections.
What should I use?

A.  MUTABLE

Use mutable.ArrayList when you want something with order than can change.
Use mutable.Set when you want a set you can change.
Use mutable.HashMap when you want a hash you can change.
These require:

import collection.mutable
You can convert a Java ArrayList into a Scala mutable.ArrayList with asScalaBuffer() IMMUTABLE I don't have preferences for immutable connections yet.
