Although there are other solutions to this, using java's builtin Arrays.sort method won't cut it. I put together this code to be called as a private method within your application. Enjoy!
This works great when using a String[][] compare. If you are trying to sort integers, simply change your array and take out the if (...compareTo...) business and just check which is greater.
private String[][] bubbleSortMulti(String[][] MultiIn, int compIdx) {
String[][] temp = new String[MultiIn.length][MultiIn[0].length];
boolean finished = false;
while (!finished) {
finished = true;
for (int i = 0; i < MultiIn.length - 1; i++) {
if (MultiIn[i][compIdx].compareToIgnoreCase(MultiIn[i + 1][compIdx]) > 0) {
for (int j = 0; j < MultiIn[i].length; j++) {
temp[i][j] = MultiIn[i][j];
MultiIn[i][j] = MultiIn[i + 1][j];
MultiIn[i + 1][j] = temp[i][j];
}
finished = false;
}
}
}
return MultiIn;
}
