用Graphics 中的drawLine()方法可以画出"粗"一点的线吗?

Question

能：
Graphics2D gg = (Graphics2D)g;
    gg.setStroke(new BasicStroke(2.0F,BasicStroke.CAP_ROUND,BasicStroke.JOIN_ROUND));
//2.0F是笔的粗细
//CAP_ROUND是线条端点
//JOIN_ROUND是点划线模式
    gg.drawLine((int)x0,(int)y0,(int)x1,(int)y1);
    gg.setStroke(new BasicStroke());
    //设回原来的

fillRect 或 fill3DRect 不就可以划出任意寬度的先嗎
