Hi Author, I'm reading your book 'Murach's Java Servlets and JSP, 3rd Edition' right now. I really enjoy reading it. Please keep the good work. Thanks.
Hi,
In the Comparator example given at the front of page 152, it says return r1.id = r2.id. Shouldn't it be return r1.id - r2.id, since we are using it as a comparator?
