Thread-Problem...

[Flynn]

Hi there!
I have following problem.
I created a frame with controls in it like Labels and buttons.
What I want to do is, that one labe should show me the time in second-clock.
My Code in the function init() of the JavaFX-Frame is:

Thread thread = new Thread()
 {
            public void run()
            {
                String strTime = objFF.getTime();
                objLabelTime.setText(strTime);
            }
 };
 thread.start();

The problem ist, that the time does not increase.

Please help me... thanks to all.

The Runnable/run method of a Thread only runs a single time.
That means, your code only runs once in the Thread and then the Thread dies.
Either use a loop in the run() method with Thread.sleep() or use a java.util.Timer.
In addition, depending on the actual accuracy you need, i.e. really execute EXACTLY each second, that is, when the wallclock (your system clock) advances a second, then you definitely need a combination of Thread.sleep() and a busy-loop that checks whether actually a second has passed and not just 999 ms. for your wallclock time readout to be correct. That is because Thread.sleep() is not accurate to the millisecond, only roughly to about 10 or 15 milliseconds.
