Hi,

I like the idea of the cattle drive, and I was planning to join.

I am a bit surprised that the whole course is still on jdk1.4. I use java6 at work, and I think I would like at least java5 (generics etc ...).
Browsing randomly the mailing list, I've seen people been advised to run the compiler with the option for 1.4 to avoid compiler errors. I guess that means that the exercises do cover bits that have changed in more recent versions of java.

Is there any reason not to switch to a more recent version? What is you view on the subject?

Thank you,
Vale

Many employers still use jdk 1.4 (including mine).

I think that jdk 5 made some big changes that "hide" some Java concepts that are important for the student to be aware of.

All concepts from jdk 1.4 are transferrable to jdk 5. The converse is not true.

P.S. I agree that generics are one of the best things about jdk 5.

Indeed -- "autoboxing" is a convenience for folks who've used Java without it, but for others it's actually a real roadblock to understanding.
