Why doesn't this very simple code snippet work?

It should based on:

First of: your style is terrible. Please stick to the name and case
conventions.

You need java 5.0 to compile this code. It seems you are trying to
compile it with an old java.

Looks like the problem is your method LSet00 which should be defined as
"void LSet00(..."

After resolving the method definition problem I was able to compile and
run using version 1.5.0_09.
