Shuffling Elements of a two-dimensional array

Problem:

In a java program, create random numbers in a two-dimensional array, then shuffle them!

Output:

Original array:
24 38 15
19 63 7
87 76 57

Shuffled array:
24 38 19
63 87 15
76 57 7

Solution:

public class twoDimentionalArrays
{
  public static void main (String[] args)
  {
    int[][] list = new int[3][3];
    for (int i =0;i<list.length;i++)
    {
      for (int j=0; j<list[0].length;j++)
      {
        list[i][j] = (int) (Math.random()*100);
      }
    }
    System.out.println("Original array:");
    for (int i =0;i<list.length;i++)
    {
      for(int j =0;j<list[0].length;j++)
      {
        System.out.print(list[i][j] + "\t");

      }
      System.out.println();
    }
    
    for (int i =0;i<list.length;i++)
    {
      for(int j =0;j<list[0].length;j++)
      {
        int i1 = (int) (Math.random()*list.length);
        int j1 = (int) (Math.random()*list[j].length);
        
        int temp = list[i][j];
        list[i][j] = list[i1][j1];
        list[i1][j1] = temp;
      }
    }
    System.out.println();
    System.out.println("Shuffeled array:");
    for (int i =0;i<list.length;i++)
    {
      for(int j =0;j<list[0].length;j++)
      {
        System.out.print(list[i][j] + "\t");

      }
      System.out.println();
    }
  }
}
