The hash is a nice solution if the number and size of the ranges aren't to big, but it could consume a substantial amount of memory.

My "big string" method will be substantially slower, but it would use considerably less memory than a hash.

Also, Java's hash equivalent aren't nearly so convenient as perl's, but the big string would translate directly.
