I am learning to use JNI by following the walkthrough contained here;
http://java.sun.com/docs/books/jni/html/jniTOC.html
The only difference is that I call the files Hello instead of
HelloWorld.

I have several hundred dollars in Java books and not to mention
several hours of time invested in learning the language.
I see allot of messages and text on the Internet about people not
wanting to use Java to write programs and that they do not like Java.

I've got a program that runs fine when run from the debugger in
Eclipse, but when you execute it outwith the debugger the program
throws a ConcurrentModificationException.  It doesn't seem to be a
simple case of http://mindprod.com/jgloss/runerrormessages.html#CONCURRENTMOD

What exactly is the difference between JDK 6 SE and J2SE? Is there any

The documentation for the Enum method ordinal() states "Most programmers
