In the K&B example of Arrays.sort(ArrayTosort,Comparator) [Page 577 of SCJP 1.6 book, Chapter no. 7 same as in SCJP 1.5 book]
what value does ReSortComaprator classes object rs take when its declared by
rs = new ReSortComparator().
Its used with Arrays.sort( ), what role does the comparator play here??
