ok i have version of t code, please tell me what i need to do when i need to get out of program The INDEX NUMBER OF COLUMN IN WHICH ARE LEAST ZEROS?

class Uzd{
public static void main(String args[]){
 int mas[][]= {{3,4,7,5,0},
      {4,5,3,0,1},
      {8,2,4,0,3},
      {7,0,2,0,1},
      {0,0,1,3,0}}; 
 int nul_mas[] = new int[5];
 int nul=0;

 for(int j=0;j<5;j++){// 
  nul=0;
  for(int i=0;i<5;i++){
   if(mas[i][j]==0){ 
    nul++;
   }
  }
  nul_mas[j]=nul;
 }
 for(int i=0;i<5;i++){ 
  for(int j=0;j<5;j++){
   System.out.print(mas[i][j]);
  }
  System.out.println();
 }

 System.out.println();// atstarpe
 System.out.println("///zeros in each column///");

 for(int i=0;i<5;i++){System.out.print(nul_mas[i]);}
 System.out.println();
}}

and after running it shows:

34750
45301
82403
70201
00130

///zeros in each column/// But i need not in each column but i need to get out index of column in which zeros are least! in this situation it is column nubmer 2!!
