スレッド「AWT-EventQueue-0」の例外java.lang.ArrayIndexOutOfBoundsException：0> = 0

Question

何か私にこのエラーを説明できますか、何が起こっているのか理解できませんか？ imtringはJTableをリセットするので、cargartablaclientesメソッドを呼び出すたびに、それ以上の行は追加されません。 その後、

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)); 
} 

テーブルをロードし、コンソールで例外の表示があなたのTableModelが0の列があり、この

Answer 1

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

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

です。 0の要素は、（空）を取得することがありますしながら、

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