First off, why are you trying to add JCalendarto a JLabel? You can easily add this to a JPanel:
首先，你为什么要添加JCalendar到 a JLabel？您可以轻松地将其添加到JPanel：
JPanel panel = new JPanel();
panel.add(new JCalendar());
If you still want to add this JCalendarto a JLabelthen you need to provide a LayoutManagerto this last one in order to properly add components to it:
如果你仍然想把它添加JCalendar到 aJLabel那么你需要为最后一个提供一个LayoutManager以便正确地向它添加组件：
JCalendar calendar = new JCalendar();
JLabel label = new JLabel("Select date of birth:");
label.setLayout(new BorderLayout());
label.add(calendar, BorderLayout.EAST);
Take a look to A Visual Guide to Layout Managers.
看看布局管理器的视觉指南。
As @mKorbel says in his comment you shouldn't use NullLayoutand setBounds()method to set the component location/size. This is the task layout managers are intended for.
正如@mKorbel 在他的评论中所说，您不应该使用NullLayout和setBounds()方法来设置组件位置/大小。这是任务布局管理器的目的。
Finally:
最后：
I wanna implement Date of Birth selecting using
JCalendar.
我想使用
JCalendar.
You may want to try JDateChooserinstead, which allows selecting a date or type it by hand:
您可能想尝试一下JDateChooser，它允许选择日期或手动输入：
JDateChooser chooser = new JDateChooser();
chooser.setLocale(Locale.US);
JPanel panel = new JPanel();
panel.add(new JLabel("Date of Birth:"));
panel.add(chooser);

Using swing, just place the jDateChooser control on your form and it will be just fine
使用 Swing，只需将 jDateChooser 控件放在您的表单上就可以了
