Sorting a multi-dimensional array

[Bill Brasskey]

Hi

I have a multi-dimensional String array with 3 cols, x rows.
The value in the 3rd col is a number. I want to sort the records (rows)
according to this value. Arrays.sort won't accomodate.
Any nudge in the right direction will be GREATLY appreciated.

Well, remember that a multi-dimensional array acts like (is?) an array of arrays. In a[][], a[2] is an array. Consider iterating through the rows, sorting them.

Your easiest bet to save having to write your own three-column sort routine would be to create a class to hold the three values. Have it either implement Comparable using the number column (or write a separate Comparator). This way you can use Arrays.sort()

Hi:

Thanks much for the replies. I ended up creating a small class that implements
comparable, and was able to achieve the result I was after.

Thanks again,
