How can I put a horizontal line between vertically ordered elements?

提问by Roman

I have a set of vertically ordered elements. They are displayed with the following code:

我有一组垂直排序的元素。它们与以下代码一起显示：

JPanel myPanel = new JPanel();
myPanel.setLayout(new BoxLayout(myPanel, BoxLayout.Y_AXIS));
JButton button = new JButton("My Button");
JLabel label = new JLabel("My label!!!!!!!!!!!");
myPanel.add(button);
myPanel.add(label);

I would like to put a horizontal line between my elements (something like <hr>in html). Does anybody know how it can be done?
