    Lightbulb How can I get this to work properly -animation issue with an applet.

    I need someone to tell me what to write in the while(true) statement in order to have this animation working?

    Java Code: 
    import java.awt.*;
import java.util.*;

public class RemainingTime extends java.applet.Applet implements Runnable {
	Font f = new Font("TimesNewRoman", Font.BOLD,21);
	Date datum;
	int theDate;
	int year;
	int month;	
	int day;
	String dd;
	String hr;  
	Thread runner;
	int theHours;
	int theMinutes;	
	int theSeconds;
	public int subTotal;
	int remainingDays;
       public void start() {
	if (runner == null); {
		runner = new Thread(this);
		runner.start();
		}
	} 	  

   public void run() {
	dd = getParameter("datum");	//får värdet i "datum" från htlm filen 
	StringTokenizer tokens1, tokens2;
	tokens1 = new StringTokenizer(dd, "/");	//Tokenizing stringen med / som avgränsare. 
	year = Integer.parseInt(tokens1.nextToken());  //konvert varje token till integer. 
	month = Integer.parseInt(tokens1.nextToken());
	day = Integer.parseInt(tokens1.nextToken());  
	
	hr = getParameter("time");	//får ett värde (i "time") från htlm filen   
	tokens2 = new StringTokenizer(hr, ":");
	int hours = Integer.parseInt(tokens2.nextToken());
	int minutes = Integer.parseInt(tokens2.nextToken());
	int seconds = Integer.parseInt(tokens2.nextToken()); 	
	
	GregorianCalendar now = new GregorianCalendar();
	int thisMonth = now.get(now.MONTH);
	int thisDay = now.get(now.DAY_OF_MONTH);
	int countDays = 0;
	
	for (int i = thisMonth+1; i <= 12; i++) { 
	subTotal += countDays;      	/////////////////////////////////////////////////////////
	      switch (month){
	
	 	case 1:		//jan
		case 3:		//mars	
		case 5:		//maj
		case 7:		//juli
		case 8:		//aug
		case 10:		//okt
		case 12:		//dec
			countDays = 31;
			break;
		case 2: 	// feb 2009
			countDays = 28;
			break;
		case 4:	//apr	
		case 6:	//juni		
		case 9:	//sept
		case 11:	//nov
			countDays = 30;
			break;
	   }
	}
	remainingDays = subTotal + thisDay;
	int thisHour = now.get(now.HOUR);	
	int thisMinute = now.get(now.MINUTE);
	int thisSecond = now.get(now.SECOND);
	int timeInSec = (thisHour*60*60) + (thisMinute*60) + thisSecond;
	int finish = (hours*60*60) + (minutes*60) + seconds;
	int totalRemSec;
	if (timeInSec > finish) 
		totalRemSec = 86400 - timeInSec + finish;
	else
		totalRemSec = finish - timeInSec;
 
	int totalMin = totalRemSec / 60;
	theHours = totalMin / 60;
	theMinutes = totalMin % 60;
	theSeconds = totalRemSec % 60;

	Thread thisThread = Thread.currentThread();
	while (runner == thisThread) {
	while(true){
		 repaint();
		try {Thread.sleep(1000);}	
		catch(InterruptedException e) {}
	}
 	}		
    }

     public void paint(Graphics s) {
	
	
	s.setFont(f);
	s.drawString("Remaining time to year 2010:", 5, 25);
	s.drawString((String.valueOf(remainingDays)), 5, 50); 
	s.drawString("days", 50, 50);
	s.drawString((String.valueOf(theHours)), 5, 75);
	s.drawString("hours", 50, 75);
	s.drawString((String.valueOf(theMinutes)), 5, 100);
	s.drawString("minutes", 50, 100);
	s.drawString((String.valueOf(theSeconds)), 5, 125);
	s.drawString("seconds", 50, 125);
     }
}

    Nothing. Use a SwingTimer to control animations. The setup can be done in init(), rather than making it Runnable. You can parse a whole date at once using DateFormat.
