Java - Selecting a random shape from pre-designed shapes

I'm having a problem randomly selecting a shape from pre-designed shapes in Java. Previously, I was able to create a random shape but I'm getting no-where with this.

My code is below. I need "DIE07" to randomly be DIE01-DIE06. All help is very much appreciated.

import java.awt.*;
import javax.swing.JPanel;
import java.util.Random;


public class FigurePanel extends JPanel {
     public static final int DIE01 = 1;
     public static final int DIE02 = 2;
     public static final int DIE03 = 3;
     public static final int DIE04 = 4;
     public static final int DIE05 = 5;
     public static final int DIE06 = 6;
     public static final int DIE07 = 7;
     Random rand = new Random();

     private int type = 1;
     private boolean filled = false;

     public FigurePanel() {
     }

     public FigurePanel(int type) {
     this.type = type;
     }

     @Override
     protected void paintComponent(Graphics g) {
     super.paintComponent(g);

     int width = getWidth();
     int height = getHeight();

     switch (type) {
     case DIE01:
     g.setColor(Color.BLACK);
     g.drawRoundRect((int)(0.1 * width), (int)(0.25 * height),
        (int)(0.8 * width), (int)(0.5 * height), 20, 20);
     g.fillOval((int)(0.44 * width), (int)(0.46 * height),
            (int)(0.1 * width), (int)(0.075 * height));
     break;
   case DIE02:
      g.setColor(Color.RED);
      g.drawRoundRect((int)(0.1 * width), (int)(0.25 * height),
          (int)(0.8 * width), (int)(0.5 * height), 20, 20);
      g.fillOval((int)(0.27 * width), (int)(0.34 * height),
              (int)(0.1 * width), (int)(0.075 * height));
      g.fillOval((int)(0.63 * width), (int)(0.58 * height),
              (int)(0.1 * width), (int)(0.075 * height));

    }

    @Override
    public Dimension getPreferredSize() {
    return new Dimension(80, 80);
    }
    }

and this...

    import javax.swing.*;

    add(new FigurePanel(FigurePanel.DIE05));
    add(new FigurePanel(FigurePanel.DIE06));
    add(new FigurePanel(FigurePanel.DIE07));
    }

    public static void main(String[] args) {
    TestFigurePanel frame = new TestFigurePanel();
    frame.setSize(1100, 300);
    frame.setTitle("TestFigurePanel");
    frame.setLocationRelativeTo(null); // Center the frame
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
