我有一个字符串

String s = "01 NOVEMBER 2012";

那我想把它解析为sqlDate,

然后我会将其插入数据库

有可能将该字符串解析为sqlDate吗？!？!

是的,sql日期格式是"yyyy-mm-dd"

我有JComboBox2列,我有JButton.单击时JButton,我需要分别JComboBox从第一列和第二列中获取所选值的结果...

我怎么这样？

另外:如何设置JComboBox的标头？

代码:

 public class Combo extends JFrame implements ActionListener{
    private JComboBox combo = new JComboBox();
    private JButton button = new JButton();
    public Combo() {

        setLayout(new FlowLayout());
        combo.setRenderer(new render());

        add(combo);

        combo.addItem(new String[] {"1","bbb"});
        combo.addItem(new String[] {"2","ff"});
        combo.addItem(new String[] {"3","gg"});
        combo.addItem(new String[] {"4","ee"});

        add(button);
        button.addActionListener(this);
        pack();
    }


    public static void main(String[]args){
        new Combo().setVisible(true);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if(e.getSource()==button){
            System.out.println(combo.getSelectedItem());
        }
    }
}
class render extends JPanel implements ListCellRenderer{

    private …
