google.ps，IllegalArgumentException

Question

你好我写这段代码，当我执行它时，给我以下例外，请帮助克服它::

try{
   model.insertRow(model.getRowCount(), new Object[]jTextField1.getText(),jTextField2.getText(),jTextField3.getText(),String.valueOf(jComboBox1.getSelectedItem())+"/"+String.valueOf(jComboBox2.getSelectedItem())+"/"+String.valueOf(jComboBox3.getSelectedItem()),jTextField4.getText(),jTextField5.getText()});
   ps=con.prepareStatement("insert into Outcome(OutID,Description,MoneyAmount,ODate,Notes)values(?,?,?,?,?)");
   ps.setString(1,jTextField1.getText());
   ps.setString(2,jTextField2.getText());
   ps.setString(3, jTextField3.getText());
   ps.setString(4,String.valueOf(jComboBox1.getSelectedItem())+"/"+String.valueOf(jComboBox2.getSelectedItem())+"/"+String.valueOf(jComboBox3.getSelectedItem()));
   ps.setString(5,jTextField4.getText());

   ps.executeQuery();

   ps.close();
   con.close();}

 catch(Exception ex){

          }             
    }

这给我以下例外：

我认为初始化对象时代码中存在错误：

new Object[]jTextField1.getText(),jTextField2.getText(),jTextField3.getText(),String.valueOf(jComboBox1.getSelectedItem())+"/"+String.valueOf(jComboBox2.getSelectedItem())+"/"+String.valueOf(jComboBox3.getSelectedItem()),jTextField4.getText(),jTextField5.getText()}

{之后，你错过了一个开放的new Object。它应该是这样的：

new Object[]{jTextField1.getText(),jTextField2.getText(),jTextField3.getText(),String.valueOf(jComboBox1.getSelectedItem())+"/"+String.valueOf(jComboBox2.getSelectedItem())+"/"+String.valueOf(jComboBox3.getSelectedItem()),jTextField4.getText(),jTextField5.getText()}
