How to show the version number in Java control panel?

System.out.println(System.getProperty("java.version"));

Or, for more complete information, see properties java.version, java.vm.version, java.specification.version & java.runtime.version.

jcomeau@intrepid:/tmp$ cat test.java; java test
public class test {
 public static void main(String[] args) {
  System.out.println(System.getProperty("java.version"));
 }
}
1.6.0_24

I believe this will work in the control panel as it does from the command line.
