hi all,here is the samle code from JLS 8.3.2.3 regarding field initialization, I already comment-off what author marked "error", but it still have problems of "forward reference". I also include error from javac. Can anybody explain? Does the author wrong, or Sun's compiler does not strict follow JLS?

errors:

Hi Haining,
The author screwed up! Static blocks are executed at class load time in the order of top down. Since you are not declaring x before you are trying to assign it you will get errors. If you move the static int x; declaration above static block it will not complain about that.
I would think that you would have the same problem with the instance declarations.
Regards,
Manfred.

Let me get this straight.
Sun writes some sample code just to show you what NOT TO DO, and you are trying to get it to COMPILE? They NEVER said that the thing would ever work. They ONLY said "Don't do this".
Perhaps you would be better of just absorbing the intent of the example.
 
Don't get me started about those stupid light bulbs.
