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

Dear,
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?
 
It is sorta covered in the JavaRanch Style Guide.
