Java: How to sort part of a 3d array? -

i have array: array[2][7][2].

for (int = 0; < 2; i++) {     (int j = 0; j < 7; j++) {         syso(array[i][j][0] + " ");     }     syso("/n"); } 

currently above code prints out:

4 1 2 5 9 0 1

2 3 1 9 9 3 1

is there way have these sorted somehow? don't care array[i][j][1], array[i][j][0].

i wrote myself quicksort function random piece of code doesn't work:

for (int = 0; < array.length; i++) {     quicksort(array[i][0], 0, array[i].length - 1);      } 

edit:

here's quicksort function well:

static int partition(int a[], int l, int r) {     int pivot = a[r];     int k=l-1;      for(int i=l; <= r; i++) {         if (a[i] <= pivot) {             k++;              int w = a[i];             a[i] = a[k];             a[k] = w;         }     }     return k; }  static void quicksort(int [] a, int l, int r) {     if (l>=r) {         return ;     }      int k = partition(a, l, r);     quicksort(a, l, k-1);     quicksort(a, k+1, r); } 

int[][] = int[2][7]; (int = 0; < array.length; i++) {    (int j = 0; j < array.length; j++) {       anotner[i][j] = array[i][j][0];    } } (int[] : anotner) {     arrays.sort(a); } 

then print anotner using syso().
