Hi Friend,

Try the following code:

import java.util.*;
public class ShuffleMultiDimensionalArray {

  static final int size = 5;
  private int[][] array = new int[size][size];
  private List<Integer> list = new ArrayList<Integer>();

  public ShuffleMultiDimensionalArray()  {
     for (int i = 0; i < size*size; i++){
      list.add(i);
    }
    for (int i = 0; i < size; i++){
      for (int j = 0; j < size; j++){
        array[i][j] = list.get(j + i * size);
      }
    }
  }
  public void shuffle(){
    Collections.shuffle(list);
    for (int i = 0; i < size; i++){
      for (int j = 0; j < size; j++){
        array[i][j] = list.get(j + i * size);
      }
    }
   }
    public String toString(){
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i < array.length; i++){
      for (int j = 0; j < array[i].length; j++){
        sb.append(String.format("%4s", array[i][j]));
      }
      sb.append("\n");
    }
    return sb.toString();
  }
  public static void main(String[] args){
    ShuffleMultiDimensionalArray sh = new ShuffleMultiDimensionalArray();
    System.out.println(sh);
    sh.shuffle();
    System.out.println(sh);
    }
}

Thanks
