[Solved] char multidimensional array sorting in java [closed]

by


Assuming you know how to sort a 1d array (otherwise look it up), this is fairly similar.

Instead of swapping two chars (when you use bubble sort or any other sorting algorithm based on swapping items), you swap the two complete rows.
So you get something like this (for bubble sort):

for char1 of each_last_row_char
  for char2 of each_last_row_char_after_char1
    if char2 < char2 then
      swap rows of char1 and char 2
    end
  end
end

Swapping complete rows is not that difficult as well. You iterate over the amount of items in the rows (assuming they have the same amount of chars), and swap the items of both rows:

for index of row_items
  tmp = row1[index]
  row1[index] = row2[index]
  row2[index] = tmp
end

Just like a regular swap implementation, but then for all items.
