 Opening an editor, typing all that in, running the java compiler, and
then running the compiled program all seems like a lot of work to me
when all you need to do is:
 $ perl -nE "say substr($_, 2, 12) if $_ =~ m/java/i;" < login.com

It is not Java but Groovy, so compile is optional.
And groovysh does have an -e for evaluating code given in command line
(it is just rarely used).
But you are absolutely right: Perl code is shorter than Groovy code.
