Get back an object

Question

Hi...
I needed return two values from a method, then I make an object for that.
But, I can't get back it.
this is the class
public class SqlTcuen
  public class Tticu {
    String coditicu;
    String nombticu;
    public Tticu(String incoditicu, String innombticu) {
      coditicu = incoditicu;
      nombticu = innombticu;
    public String getCoditicu() {
      return coditicu;
    }and this is the method where I return the object...
public class SqlTcuen
  public Vector getCodiNombTticu() {
    Vector codinombticu = new Vector();
    try {
      PreparedStatement pstmt = Connect.conn.prepareStatement(
          "{call sp_select_tticu()};", ResultSet.
          TYPE_SCROLL_SENSITIVE,
          ResultSet.CONCUR_READ_ONLY
      ResultSet r = pstmt.executeQuery();
      while (r.next()) {
        codinombticu.add(new Tticu(r.getString("coditicu"),
                                   r.getString("nombticu")));
      r.close();
      pstmt.close();
    catch (SQLException e) {
      System.out.println("FAILED: Prepare select() failed: " +
                         e.getErrorCode());
    return codinombticu;
  }public class IntCuentaContable
extends JInternalFrame
and this is de code where I try to get it.
  private void filljCBoxTipoCuenta() {
    for (int i = 0; i < sqltcuen.getCodiNombTticu().size(); i++) {
      jCBoxTipoCuenta.addItem(sqltcuen.getCodiNombTticu().get(i));
      sqltcuen.prueba(i);
  }

Answer 1

Ok, that's easy. Perform a cast when you retrieve the items from the sqltcuen object to Tticu. Rename the getCoditicu() to toString() in the Tticu class, and you are done. Your code would look like this:
Changes to SqlTcuen class:
public class SqlTcuen {
    public String toString() {      return coditicu;    }
Changes to IntCuentaContable class:
jCBoxTipoCuenta.addItem((SqlTcuen) sqltcuen.getCodiNombTticu().get(i));Your code should work properly now.
One good-willed advice: in your filljCBoxTipoCuenta(), getCodiNombTticu() is called repeatedly in the for loop. This would caused your application to connect to the database on every call. You should only call getCodiNombTticu() once before the for loop and access the Vector object returned. After making the changes, your code might look like this:
private void filljCBoxTipoCuenta() {
    Vector results = sqltcuen.getCodiNombTticu();
    for (int i = 0; i < results.size(); i++) {
        jCBoxTipoCuenta.addItem((SqlTcuen) results.get(i));
        sqltcuen.prueba(i);
}
