BasicStroke的类声明中的颜色默认sRGB颜色空间或颜色的任意颜色空间中的颜色确定。
类的声明
以下是声明的java.awt.BasicStroke类：
public class BasicStroke extends Object implements Stroke
字段域
以下是java.awt.geom.Arc2D类字段：
-
static int CAP_BUTT -- 结束未封闭的子路径和虚线线段与不加装饰。
-
static int CAP_ROUND -- 结束未封闭的子路径和虚线线段与一个圆形的装饰，有一个半径等于一半的笔宽。
-
static int CAP_SQUARE -- 结束未封闭的子路径和虚线段的具有方形的突起，伸出的端部的线宽度的一半的距离等于的段。
-
static int JOIN_BEVEL -- 加入通过其广泛的轮廓用直线段连接外眼角的路径段。
-
static int JOIN_MITER -- 加入路径段延伸的外边缘，直到他们满足。
-
static int JOIN_ROUND -- 加入路径段，通过舍入的拐角处的半径处的线宽度的一半。

类方法
| S.N. | 方法和说明 |
|---|---|
| 1 |
Shape createStrokedShape(Shape s) Returns a Shape whose interior defines the stroked outline of a specified Shape. |
| 2 |
boolean equals(Object obj) Tests if a specified object is equal to this BasicStroke by first testing if it is a BasicStroke and then comparing its width, join, cap, miter limit, dash, and dash phase attributes with those of this BasicStroke. |
| 3 |
float[] getDashArray() Returns the array representing the lengths of the dash segments. |
| 4 |
float getDashPhase() Returns the current dash phase. |
| 5 |
int getEndCap() Returns the end cap style. |
| 6 |
int getLineJoin() Returns the line join style. |
| 7 |
float getLineWidth() Returns the line width. |
| 8 |
float getMiterLimit() Returns the limit of miter joins. |
| 9 |
int hashCode() Returns the hashcode for this stroke. |

BasicStroke 实例
选择使用任何编辑器创建以下java程序 D:/ > AWT > com > zaixian > gui >
AWTGraphicsDemo.javapackage com.zaixian.gui; import java.awt.*; import java.awt.event.*; import java.awt.geom.*; public class AWTGraphicsDemo extends Frame { public AWTGraphicsDemo(){ super("Java AWT Examples"); prepareGUI(); } public static void main(String[] args){ AWTGraphicsDemo awtGraphicsDemo = new AWTGraphicsDemo(); awtGraphicsDemo.setVisible(true); } private void prepareGUI(){ setSize(400,400); addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent windowEvent){ System.exit(0); } }); } @Override public void paint(Graphics g) { Graphics2D g2 = (Graphics2D)g; g2.setStroke(new BasicStroke(3.0f)); g2.setPaint(Color.blue); Rectangle2D shape = new Rectangle2D.Float(); shape.setFrame(100, 150, 200,100); g2.draw(shape); Rectangle2D shape1 = new Rectangle2D.Float(); shape1.setFrame(110, 160, 180,80); g2.setStroke(new BasicStroke(1.0f)); g2.draw(shape1); Font plainFont = new Font("Serif", Font.PLAIN, 24); g2.setFont(plainFont); g2.setColor(Color.DARK_GRAY); g2.drawString("TutorialsPoint", 130, 200); } }
编译程序，使用命令提示符。进入到D:/> AWT，然后键入以下命令。
D:AWT>javac comzaixianguiAwtGraphicsDemo.java
如果没有错误出现，这意味着编译成功。使用下面的命令来运行程序。
D:AWT>java com.zaixian.gui.AwtGraphicsDemo
验证下面的输出
