Objects As Return Types

You can write methods that return objects. For example, findCenter takes a Rectangle as an argument and returns a Point that contains the coordinates of the center of the Rectangle:

  public static Point findCenter (Rectangle box) {
    int x = box.x + box.width/2;
    int y = box.y + box.height/2;
    return new Point (x, y);
  }

Notice that you can use new to create a new object, and then immediately use the result as a return value.
