在applet中创建一个三角形多边形

Question

        int size = RNG.randomNum(0, ((1000/numOfShapes)*10));
        int xOrigin = RNG.randomNum(0, 2000);
        int yOrigin = RNG.randomNum(0, 1080);

        int[] xPoints = null;
        int[] yPoints = null;
        Polygon p = new Polygon(xPoints, yPoints,3);
        //g2.draw(new Line2D.Double(xOrigin, yOrigin, xOrigin+size, yOrigin+size));
        //g2.draw(new Line2D.Double(xOrigin+size, yOrigin+size, xOrigin + size, yOrigin));
        //g2.draw(new Line2D.Double(xOrigin, yOrigin, xOrigin+size, yOrigin));
        g2.fillPolygon(p);

使用3次g2.draw使我成为一个很好的直角三角形，但我想让它充满一种颜色。我应该如何将这些点转换为三角形多边形，以便可以填充？

Answer 1

    int xpoints[] = {xOrigin, xOrigin+size, xOrigin + size};
    int ypoints[] = {yOrigin , yOrigin+size, yOrigin};

    g2.fillPolygon(xpoints, ypoints, 3);
