Java is extremely verbose -- you need to do a LOT of typing to get anything done. Perl has a lot more built in functions to do general-purpose things. How do you reverse an array in Java? I have no idea. In Perl?
@b = reverse @a; # easy! intuitive! simple!
Java's strict typing is nice -- but a good programmer doesn't need the language to enforce that. Perl is loosely typed -- it does what you mean, while Java demands that you do things its way.
I could go on and on but I hope you get the idea.
