Default Logic error in Exercise answers (chapter 5, ex.1)

Hello
I have had this book for an embarrassingly long time but I finally got round to reading it.
Did exercise 1 for chapter 5, rectangle class (page 267 in my copy), then d/l ans from wrox site
However you have the logic wrong in your Rectangle constructor quoted below...
Code:
public Rectangle(double x1, double y1, double x2, double y2) {
    // Ensure topleft uses the smaller of x1,x2 and y1,y2
    // and topright uses the larger of x1,x2 and y1,y2
    topLeft = new Point(Math.min(x1,x2),Math.min(y1,y2));
    bottomRight = new Point(Math.max(x1,x2),Math.max(y1,y2));
Top left is minX maxY
and bottom right is maxX and MinY
I just thought I would let you know, someone might have "given up" when they got it right!
