我想得到一个使用joptionpane作为Combobox的对话框,我想接受日,月和年的值.我希望所有这些都在一个对话框中.我的意思是:

 String[] date= {"1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24","25","26","27","28","29","30","31"};
    String[] month= {"1","2","3","4","5","6","7","8","9","10","11","12"};
    String[] year={"2016","2017","2018","2019","2020"};
    JComboBox jcd = new JComboBox(date);
    JComboBox jcm = new JComboBox(date);
    JComboBox jcy = new JComboBox(date);
      jcd.setEditable(true);
      jcm.setEditable(true);
      jcy.setEditable(true);
    JOptionPane.showMessageDialog( null, jcd, "Date", JOptionPane.QUESTION_MESSAGE);
    JOptionPane.showMessageDialog( null, jcm, "Month", JOptionPane.QUESTION_MESSAGE);
    JOptionPane.showMessageDialog( null, jcy, "Year", JOptionPane.QUESTION_MESSAGE);

    int resd=(int) jcd.getSelectedItem();
    int resm=(int) jcd.getSelectedItem();
    int resy=(int) jcd.getSelectedItem();

这里的问题是我一个接一个地输入3个对话框用于输入值,我想把它作为一个具有多个组合框的单个对话框.
