Perl Functionality in Java
I think you're making a mistake trying to program in Java like you program in Perl. Each language has its own set of metaphors and idioms. To reach optimal coding velocity you will need to learn a new way of doing things. Trying to import one language's metaphors and idioms into another is only going to impede your progress.
Case in point: C programmers that program Perl as though it were C with scalars. Of course they'd be twice as efficient if they realized they could replace all their for(;;) loops with foreach, map and grep, but they concentrate so hard on making Perl feel like C that they miss them completely.
