How to fully sort 2d array in java? -

i want sort 2d array in java. example suppose have matrix

1    5    4 3    7    8 2    9    6 

after sorting, result should like

1    2    3 4    5    6 7    8    9 

please me this.

i have written following code problem

class sort2darrayfull{ public static void sort(int el[][]){     int m=0;     int n=0;     int temp=0;     int k1=1;      for(int i=0; i<el.length; i++){         for(int j=0; j<el[i].length; j++){             system.out.print(el[i][j]+" ");         }         system.out.print("\n");     }      system.out.print("\n");      for(int i=0; i<el.length; i++){         for(int j=0; j<el[i].length; j++){             for(int k=j+1; k<el[m+n].length; k++){                 if(el[i][j]>el[m+n][k1]){                      temp=el[i][j];                     el[i][j]=el[m+n][k1];                     el[m+n][k1]=temp;                  }                  k1++;                  if(k1==el[m+n].length){                     k1=0;                 }                 if(k==el[m+n].length){                     m++;                  }                  if(m==el.length){                     m=0;                     n++;                 }              }         }     }      for(int i=0; i<el.length; i++){         for(int j=0; j<el[i].length; j++){             system.out.print(el[i][j]+" ");         }         system.out.print("\n");     } } public static void main(string... args){     sort(new int[][]{{1,5,7,2},{55,44,11,77,33},{15,19,16,14,12,13}}); } 

}

and output of program

//before sorting

1 5 7 2

55 44 11 77 33

15 19 16 14 12 13

//after sorting

19 15 44 55

1 7 5 77 33

2 11 16 14 12 13

but want result this

1 2 5 7

11 12 13 14 15

16 19 33 44 55 77

if u, i'll follows:

public static void sort(int el[][]){     for(int i=0; i<el.length; i++){         for(int j=0; j<el[i].length; j++){             system.out.print(el[i][j]+" ");         }         system.out.print("\n");     }     arraylist<integer> arraytosort = new arraylist<integer>();     (int x = 0; x < el.length; x++)     {         (int y = 0; y < el[x].length; y++)         {             arraytosort.add(el[x][y]);         }     }     integer[] sortedarray = new integer[arraytosort.size()];     sortedarray = arraytosort.toarray(sortedarray);     arrays.sort(sortedarray);     int sequence = 0;     (int x = 0; x < el.length; x++)     {         (int y = 0; y < el[x].length; y++)         {             el[x][y] = sortedarray[sequence++];         }     }     system.out.println("\nafter:");     for(int i=0; i<el.length; i++){         for(int j=0; j<el[i].length; j++){             system.out.print(el[i][j]+" ");         }         system.out.print("\n");     } }
