Help w/ Tortoise and Hare Program

[JaJavaBuddy]

Hi, I need to complete this assignment. Everything seems to work except I need to output "T" and "H" along the dashed lines (respectively) everytime either the Tortoise or the Hare moves. Here is my code, thank you in advance.

import javax.swing.JOptionPane;

public class Tort
{
    public static void main(String[] args) 
        {
            Races app = new Races();
            boolean Choice = true;

            app.displayTrack();
            app.beginRace();
            app.moveRacers();
            app.tieCheck();
            app.displayWinner();
            app.raceReset();
            /*while (Choice)
            {
                String option = JOptionPane.showInputDialog("Run Again?");
                if (option.equals("y"))
                    Choice = true;      
                else 
                    Choice = false;
            }*/
        }
}




public class Races 
{
    String [] ttrack = new String [70];
    String [] htrack = new String [70];
    int tort = 0;
    int hare = 0;

    public Races()
    {

    }

    public void beginRace()
    {
        System.out.println("BANG !!!!!");
        System.out.println("AND THEY'RE OFF !!!!!");
    }

    public void displayTrack()
    {
        for (int trackLoop = 0; trackLoop < 70; trackLoop++)
        {
            ttrack[0] = "T";
            for (int tLoop = 1; tLoop < 70; tLoop ++)
                ttrack[tLoop] = "-";

            htrack[0] = "H";
            for (int hLoop = 1; hLoop < 70; hLoop ++)
                htrack[hLoop] = "-";

            for (int rtLoop = 0; rtLoop < ttrack.length; rtLoop ++)
                System.out.print(ttrack[rtLoop]);
                System.out.print("\n");

            for (int rhLoop = 0; rhLoop < htrack.length; rhLoop ++)
                System.out.print(htrack[rhLoop]);
                System.out.print("\n"); 


        }
    }

You need to fill the strings ttrack and htrace with dashes after you create them. Then your code to substitute the dash with 'T' or 'H' will work. You also need to display the strings after each round of moveRacers(). Also, your code will not set the correct element in the string unless you also keep track of their current position, and set that position with the 'T' or 'H', and not the element at 'tort' or 'hare'. IE, you need to add that computed value to the last position to determine where each is in the race.

String [] ttrack = new String []{"-"};
String [] htrack = new String []{"-"};

I've declared them w/ dashes but this will only fill one space, is there a way to declare will all spots (70) filled?

Were you able to figure out how to fix it? I'm interested in seeing how it turned out. Thanks.
