It tried to cover a lot of things Java can do, but it did not provide enough details and examples to show us how to do it. I read several Java books from the SUN press, but every time it disappointed me. I like Java programming a lot, don't mistaken me, but SUN's writers are not as good as some other publisher like the Waite group, or SAMS. Take a look at the book from BORDERS or B&N and you will understand.
