是否可以在GeneralPath上使用BasicStrokes连接类型？

Question

我有一个用GeneralPath制作的多边形，我做了一个基本的笔触，线条粗细为8，并将连接类型设置为JOIN_MITER。当我尝试绘制这样的形状时：

g2d.setStroke(stroke);
g2d.draw(generalPath);

它使用正确的线条粗细绘制形状，但它会像处理自己的线条一样处理每条线条，给出它在笔划中定义的任何类型的端盖。 CAP_ROUND看起来最好，但我更喜欢if行与JOIN_MITER正确连接。可以这样做吗？我使用GeneralPath时是否使用了正确的类？任何帮助或建议将不胜感激。

对于上下文，这里的类被剥离到相关信息。 paintComponent方法是从我正在绘制的JPanel的paintComponent方法调用的，它有一个这样的arrayList，它迭代通过并一次调用它们的paintComponent方法：

public class RShape extends RComponent{
    GeneralPath linkedLines;
    Stroke stroke;
    public RShape(int x, int y, int sides, Stroke stroke, int defaultLineLength) {
        this.stroke = stroke;
        linkedLines = new GeneralPath();
        double angle = ((double)360)/sides;//find what the angles would need to be to make a shape with that many sides
        double dStartX = x;
        double dStartY = y;
        double nextAngle;
        for(int i=0;i<sides;i++) {
            nextAngle = angle*i;
            nextAngle = nextAngle * Math.PI / 180;//convert to radians
            double dEndX = dStartX + defaultLineLength * Math.sin(nextAngle);//find where the end of the line should be for the given angle and line length
            double dEndY = dStartY + defaultLineLength * Math.cos(nextAngle);
            int endX = (int) Math.round(dEndX);//round to the nearest int
            int endY = (int) Math.round(dEndY);
            int startX = (int) Math.round(dStartX);
            int startY = (int) Math.round(dStartY);
            linkedLines.moveTo(startX, startY);//add the next segment of the GeneralPath
            linkedLines.lineTo(endX, endY);
            dStartX = dEndX;//move the starting point to the end point so it's ready for the next loop
            dStartY = dEndY;
        }
        linkedLines.closePath();//close the last gap.
    }
    public void paintComponent(Graphics2D g2d) {
        g2d.setStroke(stroke);
        g2d.draw(linkedLines);
    }
}

这就是这样的：

ComponentList components = new ArrayList<RComponent>();
components.add(new RShape(50,50,5,new BasicStroke(8,BasicStroke.CAP_BUTT,BasicStroke.JOIN_MITER),60));
