如何從JSpinner結果值設置日曆？

如何設置兩個jspinner的日曆？

的JSpinner 1 =月份值

的JSpinner 2 =年份值

也許這只是爲了讓從JSpinner的int值.. 怎麼辦呢？

這裏是我的代碼：（更新）

import java.awt.BorderLayout; 
import java.text.SimpleDateFormat; 
import java.util.Calendar; 
import java.util.Date; 
import javax.swing.JFrame; 
import javax.swing.JLabel; 
import javax.swing.JSpinner; 
    import javax.swing.SpinnerDateModel; 
    import javax.swing.event.ChangeEvent; 
    import javax.swing.event.ChangeListener; 


    public class datepicker extends JFrame{ 
     JSpinner Smonth = new JSpinner(); 
     JSpinner Syear = new JSpinner(); 
     Calendar cal = Calendar.getInstance(); 
     Date date = cal.getTime(); 
     SimpleDateFormat sdf_Month = new SimpleDateFormat("MM"); 
     SimpleDateFormat sdf_Year = new SimpleDateFormat("yyyy"); 
     SimpleDateFormat sdf_final_Date = new SimpleDateFormat("MMMM yyyy"); 
     JLabel label = new JLabel(); 

     datepicker(){ 
      Smonth.setModel(new SpinnerDateModel(date, null, null, cal.MONTH)); 
      Smonth.setEditor(new JSpinner.DateEditor(Smonth, "MMMM")); 
      Syear.setModel(new SpinnerDateModel(date, null, null, cal.YEAR)); 
      Syear.setEditor(new JSpinner.DateEditor(Syear, "yyyy")); 

      Smonth.addChangeListener(new ChangeListener() { 

       @Override 
       public void stateChanged(ChangeEvent e) { 
        execute(); 

       } 
      }); 

      Syear.addChangeListener(new ChangeListener() { 

       @Override 
       public void stateChanged(ChangeEvent e) { 
        execute(); 

       } 
      }); 

      setLayout(new BorderLayout()); 
      add(Smonth, BorderLayout.WEST); 
      add(label, BorderLayout.CENTER); 
      add(Syear, BorderLayout.EAST); 

      execute(); 
     } 

      void execute(){ 


       cal.set(Integer.parseInt(sdf_Year.format(Syear.getValue())), 
        (Integer.parseInt(sdf_Month.format(Smonth.getValue())))-1, 
        1); 

       label.setText(sdf_final_Date.format(cal.getTime())); 
      } 

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

請閱讀教程約JSpinner
有詳細desirbtions關於JSpinner,SpinnerDateModel，INC。有關教程中的代碼示例

編輯

有沒有理由去解析什麼，用正確的SpinnerXxxModel，
你可以測試，如描述分裂三個JSpinners SpinnerDateModel的教程，簡單代碼

我已經讀過它，真的搞不清它.. 更新我的代碼..我想我做什麼，它不是一個好辦法..有其他好方法？真的真的謝謝你的幫助和建議.. –

'和真的混淆它接受'接受，在教程中描述了三種方法1）SpinnerListModel約字符串值，使用情況下，你想顯示月份名稱2）SpinnerNumberModel，如果你想爲所有三個JSpinners（日，月和年）使用munbers，3）最重要的是使用返回Date實例的SpinnerDateModel，或者4）我會更新一些關於JSpinner和SpinnerDateModel的代碼，休息取決於你，沒有理由從JSpinner解析整數或munber實例，僅使用SpinnerNumberModel – mKorbel

thankz ..我已經學習了你的腳本（它需要很長時間才能理解〜，〜「，但最後我得到了它），但我仍然混淆瞭如何獲得與我的腳本的關係..（原諒我的愚蠢）... 我需要詮釋月份價值e設置我的日曆..然後用我的日曆我設置我的jlabel [日]基於日曆（月）..我更新我的日期選擇器的完整代碼..如何做到這一點，而無需從jspinner結果解析simpledateformat int？ –

把適當的參數類型，即：

cal.set(Integer.parseInt(sdf_Year.format(Syear.getValue())), 
      Integer.parseInt(sdf_Month.format(Smonth.getValue())), 
      1);
