Horse Racing Design in Java

Dear reader,
Here I am writing a "Horse Racing" design which is generally asked in Interview questions in Java for
Experienced people.

//This is the main class, you have to execute.
public class HorseRace {
    public static void main( String args[] ) {
        Horse[] horseArray = new Horse[4];  //Initializing 4 Horses
        for (int i=0; i<horseArray.length; i++) {
            horseArray[i] = new Horse(i+1);
        }
        System.err.println( "!!!!!!!!!Starting race!!!!!!!!" );
        Horse.resetRace();
        for (int i=0; i<horseArray.length; i++) { 
            horseArray[i].start();
        }
        
        Reporter rpt = new Reporter(horseArray);
        rpt.start();
    }
}

//The below Reporter class is for Displaying purpose, which shows the Horse and Distance Status
public class Reporter extends Thread {
    Horse[] horse;
    public Reporter(Horse[] h) {
        System.out.println("And they have left ground...");
        horse = h;
    }
    public void run() {
        System.out.print("Horse Label==>");
        for (int i=0; i<horse.length; i++) {
            System.out.printf("%5d ", (i+1));
        }
        System.out.println();
        while (!Horse.done()) {
            System.out.println();
            System.out.print("Distance      ");
            for (int i=0; i<horse.length; i++) {
                System.out.printf("%5d ", horse[i].getDistance());
            }
        }
        System.out.print("\r");
        System.out.print("Distance      ");
        for (int i=0; i<horse.length; i++) {
            System.out.printf("%5d ", horse[i].getDistance());
        }
        System.out.println("\nAnd the winner is "+ Horse.getWinner());
    }
}

//This is the actual Horse class, we need as many Instances of this class as number of Horse. Check the 
//main class for the same.

class Horse extends Thread {
    private static boolean raceOver = false;
    private static final int raceLength = 3;  //You can choose this.
    private static String winner = "";
    private int distance;
    private String name = "";

    public Horse(int id) {
        name = "Horse #" + id;
        distance = 0;
    }

    public static void resetRace() { 
        raceOver = false; 
    }
    public static boolean done() { 
        return raceOver; 
    }
    public static String getWinner() { 
        return winner; 
    }
    public int getDistance() { 
        return distance; 
    }

    public void run() {
        while (!raceOver) {
            try {
                //Get a little rest and then move
                Thread.sleep((int)(Math.random() * 500));
                if (++distance >= raceLength) 
                    raceOver = true;
            } catch (InterruptedException e) {
                System.err.println(e);
            }
        }
        if (distance == raceLength) winner = name;
    }
}

//Output:

!!!!!!!!!Starting race!!!!!!!!
And they have left ground...
Horse Label==>    1     2     3     4 

Distance          0     0     0     0 
Distance          0     0     0     0 
------------
------------
------------
Distance          1     2     1     0 
Distance          1     3     1     0 
And the winner is Horse #2

//You can see the Horse Label 2 has completed the distance/race length first.
