How to draw bones in java?

Question

Red Dice I was working on a craps game for a class, and I cannot finish the code because I do not know how to draw the actual points on the matrix. I have a table, and the actual mind is simply not dots on the bones. I need help drawing them. And the bones are red. This is what I have:

// Draws a given number of dots on this die
private void drawDots(Graphics g, int x, int y, int numDots)
    {
    g.setColor(Color.WHITE);

    int dotSize = dieSize / 4;
    int step = dieSize / 8;
    int x1 = x + step - 1;
    int x2 = x + 3*step;
    int x3 = x + 5*step + 1;
    int y1 = y + step - 1;
    int y2 = y + 3*step;
    int y3 = y + 5*step + 1;

    switch (numDots)
    {
      case 1:
    g.fillOval(x2, y2, dotSize, dotSize);
    break;
  case 2:
    g.fillOval(x3, y1, dotSize, dotSize);
    g.fillOval(x1, y3, dotSize, dotSize);
    break;
  case 3: 
    g.fillOval(x1, y1, dotSize, dotSize);
    g.fillOval(x2, y2, dotSize, dotSize);
    g.fillOval(x3, y3, dotSize, dotSize);
    break;
  case 4:
    g.fillOval(x1, y1, dotSize, dotSize);
    g.fillOval(x3, y3, dotSize, dotSize);
    g.fillOval(x1, y3, dotSize, dotSize);
    g.fillOval(x3, y3, dotSize, dotSize);
    break;
  case 5: 
    g.fillOval(x1, y1, dotSize, dotSize);
    g.fillOval(x2, y2, dotSize, dotSize);
    g.fillOval(x3, y1, dotSize, dotSize);
    g.fillOval(x1, y3, dotSize, dotSize);
    g.fillOval(x3, y3, dotSize, dotSize);
    break;
  case 6:
    g.fillOval(x1, y1, dotSize, dotSize);
    g.fillOval(x2, y1, dotSize, dotSize);
    g.fillOval(x3, y1, dotSize, dotSize);
    g.fillOval(x1, y3, dotSize, dotSize);
    g.fillOval(x2, y3, dotSize, dotSize);
    g.fillOval(x3, y3, dotSize, dotSize);
    break;


}

}
}

I do not know what I did wrong. When I run his dice roll, but they do not show any dots on them.

Bug fixed. My class Die.java did not say what was needed. Thanks for the help!

My class originally said:

import java.util.Random;


public class Die
{
  private final static Random random = new Random();
  public Die()
{

}
  public int getRoll()
 {
   return random.nextInt(6)+1;
  }
  public int getNumDots()
  {
    // TODO Auto-generated method stub
    return 0;
  }
}

When he should have said:

import java.util.Random;


public class Die
{
  private int sides;
  {
  }

    public void roll()
    {
      sides = (int)(Math.random()* 6 +1);
    }
    public int getNumDots()
    {
      return sides;
    }
  }
