Answer 1

One option is to use Apache Commons CollectionUtils "select" method. You would need to create a Predicate object (an object with a single "evaluate" method that uses the regular expression to check for a match and return true or false) and then you can search for items in the list that match. However, it won't return the indexes, it will return a collection containing the items themselves.
