So all you need is read a text file, split it in words, and end up with a sorted array of words?Or perhaps you are interested in the unique words in your document? In that case, a Set is more appropriate.If you do want unique words, but not a Set, tryAnd so forth. The combination of regular expressions and the Collections framework is good fun although still not as much as Perl.

I realised you may want to know the frequency of the words as well. The following code is a bit dirty, so don't show it to anyone as-is -- it will return a sorted list of words, each stating how many times it occurred in the source text:It doesn't return an array, it actually returns a Collection of Count objects. If you print them (which calls toString() on the objects) you'll get the promised list.HTH
