gi ima i source fajlovite dole.
obrati paznja na ovoj metod, vaka si igra so threadot na sekoi 1000ms:

Код:

public void run()
    {

        while (timer != null)
        {
            try
            {
               timer.sleep(1000);
            }catch (InterruptedException e)
             {
                break;
             }
            repaint();
        }
        timer=null;
    }

 

2) нишки во Java

- Креирање на applet кој ќе ни го покажува точно време, кое се проверува на секоја секунда, благодарејки на креираната нишка

import java.awt.Graphics;
import java.util.Date;

public class Clock extends java.applet.Applet implements Runnable {

Thread clockThread = null;

public void start() {
if (clockThread == null) {
clockThread = new Thread(this, "Clock");
clockThread.start();
}
}
public void run() {
// loop terminates when clockThread is set to null in stop()
while (Thread.currentThread() == clockThread) {
repaint();
try {
Thread.sleep(1000);
} catch (InterruptedException e){
}
}
}
public void paint(Graphics g) {
Date now = new Date();
g.drawString(now.getHours() + ":" + now.getMinutes() + ":" + now.getSeconds(), 5, 10);
}
public void stop() {
clockThread = null;
}
}
