Hi Cathy, you're right, there're static toString() methods to all wrappers. However, I don't think it's an error of K&B. They show common methods in the table (those you should focus on learning for the exam). And, I should admit, that table is perfectly exhaustive as far as the exam is concerned.
Hi Cathy! We are going to change that in the book, and add it to the errata page. Just as an historical FYI, prior to 1.4 those two classes did not contain static toString() methods, they were added into 1.4. Good catch! I would ask that you send us an email if you find any more errata, that way we'll be sure to capture them. Thanks, Bert
