public class Borders extends JFrame { static JPanel showBorder(Border b) { JPanel jp = new JPanel(); jp.setLayout(new BorderLayout()); String mm = b.getClass().toString(); mm = mm.substring(mm.lastIndexOf(‘.’) + 1); jp.add(new JLabel(mm, JLabel.CENTER), BorderLayout.CENTER); jp.setBorder(b); return jp; }

2 javax.swing.border
AbstractBorder所有边框类的父类
3 BorderFactory
使用工厂设计模式快速设计边框，隐藏创建细节。
4 LineBorder
LineBorder是围绕组件周围用户义定宽度的单色行边框。他可以具有方角或是圆角。 LineBorder有三个构造函数，两个工厂方法以及两个BorderFactory工厂方法
public LineBorder(Color color) Border lineBorder = new LineBorder (Color.RED);
public LineBorder(Color color, int thickness) Border lineBorder = new LineBorder (Color.RED, 5);
public LineBorder (Color color, int thickness, boolean roundedCorners) Border lineBorder = new LineBorder (Color.RED, 5, true);
public static Border createBlackLineBorder() Border blackLine = LineBorder.createBlackLineBorder();
public static Border createGrayLineBorder() Border grayLine = LineBorder.createGrayLineBorder();
public static Border createLineBorder(Color color) Border lineBorder = BorderFactory.createLineBorder(Color.RED);
public static Border createLineBorder(Color color, int thickness) Border lineBorder = BorderFactory.createLineBorder(Color.RED, 5); 5 MatteBorder
如果我们希望修改不同边的粗细，我们需要使用MatteBorder，
MatteBorder(Icon tileIcon) Creates a matte border with the specified tile icon. MatteBorder(Insets borderInsets, Color matteColor) Creates a matte border with the specified insets and color. MatteBorder(Insets borderInsets, Icon tileIcon) Creates a matte border with the specified insets and tile icon. MatteBorder(int top, int left, int bottom, int right, Color matteColor) Creates a matte border with the specified insets and color. MatteBorder(int top, int left, int bottom, int right, Icon tileIcon) Creates a matte border with the specified insets and tile icon. 6 TitleBorder
7 BevelBorder
BevelBorder以三维外观绘制边框，其可以表现为升起或是降低。当边框升起时，在边框的底部与右边会出现阴影效果。当降低时，阴影的位置会相反。 BevelBorder有三个构造函数以及一个工厂方法，同时还有BorderFactory创建BevelBorder对象的五个工厂方法：
public BevelBorder(int bevelType) Border bevelBorder = new BevelBorder(BevelBorder.RAISED);
public BevelBorder(int bevelType, Color highlight, Color shadow) Border bevelBorder = new BevelBorder(BevelBorder.RAISED, Color.PINK, Color.RED);
public BevelBorder(int bevelType, Color highlightOuter, Color highlightInner, Color shadowOuter, Color shadowInner) Border bevelBorder = new BevelBorder(BevelBorder.RAISED, Color.PINK, Color.PINK.brighter(), Color.RED, Color.RED.darker());
public static Border createBevelBorder(int bevelType) Border bevelBorder = BorderFactory.createBevelBorder(BevelBorder.RAISED);
public static Border createLoweredBevelBorder() Border bevelBorder = BorderFactory.createLoweredBevelBorder();
public static Border createRaisedBevelBorder() Border bevelBorder = BorderFactory.createRaisedBevelBorder();
public static Border createBevelBorder(int bevelType, Color highlight, Color shadow) Border bevelBorder = BorderFactory.createBevelBorder(BevelBorder.RAISED, Color.PINK, Color.RED);
public static Border createBevelBorder(int bevelType, Color highlightOuter, Color highlightInner, Color shadowOuter, Color shadowInner) Border bevelBorder = BorderFactory.createBevelBorder(BevelBorder.RAISED, Color.PINK, Color.PINK.brighter(), Color.RED, Color.RED.darker()); 8 SoftBevelBorder
oftBevelBorder是BevelBorder的近亲。这个组件会包围四角，所以他们的边并不尖利。 而他使用下边与右边的相应外边颜色只绘制一条线。 SoftBevelBorder有三个构造函数：
public SoftBevelBorder(int bevelType) Border softBevelBorder = new SoftBevelBorder(SoftBevelBorder.RAISED);
public SoftBevelBorder(int bevelType, Color highlight, Color shadow) Border softBevelBorder = new SoftBevelBorder(SoftBevelBorder.RAISED, Color.RED, Color.PINK);
SoftBevelBorder(int bevelType, Color highlightOuterColor, Color highlightInnerColor, Color shadowOuterColor, Color shadowInnerColor) 9 EtchedBorder
建立一个四周有凹痕的边界，也可以指定突边与阴影的颜色.
10 CompoundBorder
建立一个复合边界，并可以指定它的内外边界
