Ausnahme im Thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 0> = 0

Question

kann jemand mir diesen Fehler erklären, ich kann nicht verstehen, was vor sich geht? ich versuche, eine JTable so zurückzusetzen, dass ich jedesmal, wenn ich die Methode cargartablaclientes aufruft, keine weiteren Zeilen hinzufüge. und dann laden Sie die Tabelle

public void agregarnuevafila(javax.swing.JTable Table) 
{ 
    //Define temp como una variable de tipo DefaultTableModel 
    DefaultTableModel temp = (DefaultTableModel) Table.getModel(); 
    Object nuevo[] = {"","","","","","",""}; 

    //Inserta la nueva fila al objeto correspondiente 
    temp.addRow(nuevo); 
} 

public void cargartablaclientes(javax.swing.JTable jTable1, String fech) 
{ 
    int linea = 1; 
    reiniciarJTable(jTable1); 
    try 
    { 
     Connection cn = sql.Conectar(); 

     String query = "SELECT * FROM datos where fecha= '"+fech+"' "; 
     ResultSet rs = sql.stmt.executeQuery(query); 
     rs.first();   
     if (rs!=null) 
     { 
      do 
      { 
       jTable1.setValueAt(rs.getString("serie"), linea, 0); 
       jTable1.setValueAt(rs.getString("placa"), linea, 1); 
       jTable1.setValueAt(rs.getString("fecha"), linea, 2); 
       jTable1.setValueAt(rs.getString("hora_entrada"), linea, 3); 
       jTable1.setValueAt(rs.getString("tipo"), linea, 4); 
       jTable1.setValueAt(rs.getString("hora_salida"), linea, 5); 
       jTable1.setValueAt(rs.getString("total"), linea, 6); 
       linea++; 

       if (linea >= 4) 
       { 
        agregarnuevafila(jTable1); 
       }      
       rs.next(); 
      }while(rs!=null); 
     }    
    } 
    catch(SQLException ex) 
    { 
     System.out.println(ex);    
    }  

} 

public static void reiniciarJTable(javax.swing.JTable Tabla){ 
    DefaultTableModel modelo = (DefaultTableModel) Tabla.getModel(); 
    while(modelo.getRowCount()>0)modelo.removeRow(0); 

    TableColumnModel modCol = Tabla.getColumnModel(); 
    while(modCol.getColumnCount()>0)modCol.removeColumn(modCol.getColumn(0)); 
} 

und die Ausnahme-Anzeige in der Konsole ist das

Answer 1

DefaultTableModel temp = (DefaultTableModel) Table.getModel(); 
Object nuevo[] = {"","","","","","",""}; 

//Inserta la nueva fila al objeto correspondiente 
temp.addRow(nuevo); 

Ihre TableModel 0 Spalten. Sie müssen die Anzahl der Spalten festlegen, die Sie möchten, wenn Sie das schaffen JTable:

DefaultTableModel model = new DefaultTableModel(0, 7); 
JTable table = new JTable(model);
