A possible typo

[Yikai-Cao]

The output of the following statements in topics W3.2c may be wrong

public static void printPoint(Point p) {
    System.out.println("(" + p.x + ", " + p.y + ")");
}

public static void main(String[] args) {
    Point spot = new Point(3, 4);
    printPoint(spot);
}

It may be

(3, 4)

But shown as

3, 4
