For micro-edition or java generally. You can look up your question on the sun www server and get full details at Java 2 Platform, Micro Edition Home

about the differences between the JDK 1.4 and 1.5 :
1. The inboxing and outboxing feature e.g. int i = (Integer)obj;, the old style: int i = ((Integer)obj).intValue();
2. Tag feature e.g. Vector<String> vectStrings = new Vector<String>();, it means all elements will be as String value nothing else.

and more...

but about the J2ME , you can not use the features in 1.5 or 1.4 because the KVM for mobile devices it is 1.3

A further question: do you know if there are plans to update the J2ME virtual machine to support 1.4 or 1.5? And if so, when will that be?
I agree. Here's the link:
