示例1: writeShape

/** Overloaded to provide a number format. */
public String writeShape(Shape shape, NumberFormat nf) {
  if (shape instanceof Point) {
    Point point = (Point) shape;
    return nf.format(point.getX()) + " " + nf.format(point.getY());
  } else if (shape instanceof Rectangle) {
    Rectangle rect = (Rectangle) shape;
    return nf.format(rect.getMinX()) + " " + nf.format(rect.getMinY()) + " " + nf.format(rect.getMaxX()) + " "
        + nf.format(rect.getMaxY());
  } else if (shape instanceof Circle) {
    Circle c = (Circle) shape;
    return "Circle(" + nf.format(c.getCenter().getX()) + " " + nf.format(c.getCenter().getY()) + " " + "d="
        + nf.format(c.getRadius()) + ")";
