JPanel.setBorder() ：Although technically you can set the border on any object that inherits from JComponent, the look and feel implementation of many standard Swing components doesn't work well with user-set borders. In general, when you want to set a border on a standard Swing component other than JPanel or JLabel, we recommend that you put the component in a JPanel and set the border on the JPanel（建议把组件放在JPanel上，然后设置JPanel的边框）。设置面板边框，参数可以为以下边框类型：

BevelBorder	A class which implements a simple two-line bevel border.
CompoundBorder	A composite Border class used to compose two Border objects into a single border by nesting an inside Border object within the insets of an outside Border object.
EmptyBorder	A class which provides an empty, transparent border which takes up space but does no drawing.
EtchedBorder	A class which implements a simple etched border which can either be etched-in or etched-out.
LineBorder	A class which implements a line border of arbitrary thickness and of a single color.
MatteBorder	A class which provides a matte-like border of either a solid color or a tiled icon.
SoftBevelBorder	A class which implements a raised or lowered bevel with softened corners.
StrokeBorder	A class which implements a border of an arbitrary stroke.
TitledBorder	A class which implements an arbitrary border with the addition of a String title in a specified position and justification.
