HI , Learning Java is certainly a good idea and opportunity. One on the most appealing concepts in java is the oo concept, which has been put to great use. Also it surely not going to be tough for one who has coding experience and having worked on perl , I think its easy to migrate to java. Yep both the languages have their own advantages and disadvantages. I am sure you will begin to know the difference once you start working on Java and thatmuch more if you are exposed to the Enterprise environment. That a cool opportunity . Just take it. Good Luck.
