AbstractBorder所有边框类的父类

使用工厂设计模式快速设计边框，隐藏创建细节。

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);

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.

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());

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)

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.

建立一个复合边界，并可以指定它的内外边界
