Subject: Re: Sorting using servlets
Hi take a look at java.util.Arrays method (since 1.2)
public static void sort(Object[] a,
int fromIndex,
int toIndex,
Comparator c)
For your purpose you must store each output line into an array of objects.
Each
of these objects
represents a row of your output. Each row-objects has individual data
members
which
represent the columns of your output.
Then build a comparator for each column-sort. The comparator 'knows' which
of
the rows data-members it's supposed to concider for sorting and then let the
sort method do the rest!
