Re: [Java-player-users] Regarding javaclient3 execution in eclipse

Hi!

Could you please describe in details what exactly you understand with
successful and unsuccessful code execution. Where exactly your code stops
or does something unexpected?
I have used something very similar to your code [1], with only difference
that I had small delay between subsequent data readiness checks.

There is one feature worth to mention about.
>From source code of Ranger (and most others) interface:
...
public boolean isDataReady () {
  if (readyPrdata) {
    readyPrdata = false;
    return true;
  }
  return false;
}
...

This function returns true only once per data reading cycle.
In that sense your code is a bit redundant
  System.out.println(rngi.isDataReady ()); // if this will return true
  while (!rngi.isDataReady ()); // then this will wait till next data
exchange tick.
