Java アプリケーションで JXDatePicker を使用しており、その値を MySQL データベースに保存したいと考えています。格納されるデータベース値は日付型です。

これが私のコードです：

final JXDatePicker dodc = new JXDatePicker(System.currentTimeMillis());
final SimpleDateFormat formater = new SimpleDateFormat("yyyy/MM/dd");
Date datedodc;

dodc.setBounds(250, 260, 150, 20);
    content.add(dodc);
    dodc.setForeground(BLACK);
    dodc.setBackground(WHITE);
    dodc.setFont(new Font("Arial", Font.BOLD, 12));
    dodc.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
             datedodc = dodc.getDate();
            System.out.println(formater.format(dodc.getDate()));
        }
    });

この値を出力すると、次の出力が得られます。

Feb 05 00:00:00 IST 2013

日付型の値を次の形式で mysql に保存したい:yyyy-mm-dd どうすればよいですか?

値を保存しようとすると、Eclipse で次のエラーが表示されます。

これを試して：

DateFormat format = new SimpleDateFormat("yyyy-MM-dd");
dateString = format.format(date.getDate());

このアプローチを試してください：

int selectedYear =  (int)  datePicker.getModel().getYear();
int selectedMonth = (int)  datePicker.getModel().getMonth();
int selectedDay = (int)  datePicker.getModel().getDay();

String selectedDate = selectedYear +"-"+selectedMonth+"-"+selectedDay;

selectedDateをデータベースに保存できるようになりました。
