do i need install jdk1.4 to pratise java program??

[James . Liu]

Hi,
I want to take exam SCJP for 1.4. I have installed jdk1.3 on my computer. Do I need install JDK1.4 instead of 1.3 for practise java program?
Thank you very much for your help.

It would be better to install and use jdk1.4.
Jdk1.3 doesn't support assertions, and does not have the new collections classes java.util.LinkedHashMap and java.util.LinkedHashSet

Yes. You definitely need JDK1.4. I faced the same problem with JDK1.3. When I am working on assertions I didn't have compiler options to enable assertions and I didn't realize till that time. So better do it now than later.
