JAVA Netbeans: Juego Dado apuesta.... usando Jlist

Para esto uso 2 clases: una donde se encontrara el Main(Principal) ya que aqui creare el objeto que llamara al formulario, y la otra clase donde estara mi formulario.


Primera Clase (Main)


package jlistjava;

/**
* @author harold
*/
public class Main {

/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
JFrame1 harold = new JFrame1();
harold.show();
}

}



y la otra clase del Formulario que la llamare (JFrame1)

package jlistjava;

import java.util.Random;
import javax.swing.DefaultListModel;
import javax.swing.JOptionPane;

/**
* @author Harold
*/
public class JFrame1 extends javax.swing.JFrame {

//CREANDO MI CONSTRUCTOR
public JFrame1() {
initComponents();
modelo = new DefaultListModel();
LISTA.setModel(modelo);
}

//CODIGO GENERADO AUTOMATICAMENTE
