    Hello,

    I have a 2D array of ints that I need to sort independently by columns in descending order.

    For example right now I have:
    0 1 2 3 4
    5 19 7 33 9
    10 11 24 13 14
    15 16 43 30 19
    20 21 22 23 24

    and i want it to have the largest number in each column on top and and descend from there, but I don't know how to write the code.

    any ideas would be great. Thanks!

    I'd use
    Code:
    Arrays.sort(<array name>);
     
    but I can't get it to work for a 2D array.
