At page 557 :
If the collection/array you want to search was sorted using a Comparator, it must be searched using the same Comparator, which is passed as the second argument to the binarySearch() method. Remember that Comparators cannot be used when searching arrays of primitives.
Is comparator 2nd or 3rd argument to binarySearch() ?

Third argument.
Simple API questions are answerable using the Javadoc for the Java API at
http://java.sun.com/j2se/1.5.0/docs/api/. The signature for the binarySearch
that takes a comparator is:
static <T> int binarySearch(T[] a, T key, Comparator<? super T> c)
