Re: Object Oriented Orientation

should I stop where I am, and come back to learn object orientation in Perl?

It really depends on what you're learning from, and your current level of knowledge; too many new ideas introduced too quickly will only leave you confused

Safest course is finish studying your java material, learn what its trying to teach you, then revisit perl, via Beginning Perl Chapter 11: Object-Oriented Perl, followed by the Objects chapter of Modern Perl

Compare similar concepts from one to the other, and revisit any parts that make you pause or raise questions

Is the concept of object oriented languages closely related enough for the knowledge of one to help set precedence for the knowledge of another?

Learning an object-oriented-language usually only teaches you the mechanics (axle, wheels, steering, engine ... how to make object, call methods, how method dispatch works...), it doesn't teach you how to drive (what should be an class/object, what properties/methods it should have ... object oriented design)

I have to second these recommendations.

Stick with Java. First, look at the job boards these days. Java is huge and marketable. It's a good OO language to learn, and a lot of the best OO training is in Java these days.

Invest in OOAD. Learn good OO Design. A lot of the best OOAD training is in Java these days... I highly recommend the Responsibility Driven Design approach also. Object Design: Roles, Responsibilities, and Collaborations http://wirfs-brock.com/DesignBooks.html is a good book for that. You can find it on Safari also.

Take what you learn and apply it to Perl. You'll learn a lot about Perl doing that. There are lots of OO Perl programmers out there, but not a lot of great ones. Good design skill is fundamental for OO quality.

Finally, Perl is my favorite OO language to work with. It's what-you-write-is-what-you-get approach is simple and powerful. Dynamic compilation, being able to change the nature of your program taking on new responsibilities as your data and input dictate... literally seeking them out and compiling them.. very cool.
