Pessoal fiz um formulario pra cadastrar um cliente no netbeans fiz o código abaixo que está em itálico em azul e sempre dá um erro que relato abaixo.
Obs: o metodo “x.cadastra” recebe um objeto e coloca em um vetor.
package GUI;
import Objeto.Cliente;
import Objeto.Endereco;
import Operações.AcmeVideo;
public class Clientes extends javax.swing.JFrame {
/** Creates new form Clientes */
public Clientes() {
initComponents();
Cliente a=new Cliente();
IDCliente.setText("000"+a.getIdCliente());
}
/** This method is called from within the constructor to
* initialize the form.
* WARNING: Do NOT modify this code. The content of this method is
* always regenerated by the Form Editor.
*/
@SuppressWarnings("unchecked")
