如何在Java中为组件创建复合边框？

How to create a compound border for a component in Java?

合成边框由两个或多个边框组成，即边框周围的边框。我们可以使用createCompoundBorder()方法为Java中的组件创建它。

假设以下是我们的组件-

1 2	JLabel label; label = new JLabel("This has compound border (border around a border)!");

现在，设置复合边框-

1 2	label.setBorder(BorderFactory.createCompoundBorder(BorderFactory .createRaisedBevelBorder(), BorderFactory.createLoweredBevelBorder()));

以下是为组件创建复合边框的示例-
