            i = randomLocation(0, size - 1);

                counter++;
            }
        }
      
    }
    // Function which is display array elements
    public static void display(int[] arr, int size)
    {
        for (int i = 0; i < size; ++i)
        {
            // Disply element value
            System.out.print("  " + arr[i] );
        }

    }
    public static void main(String[] args)
    {
  
        // Define array of integer elements
        int[] arr = {
            1 , 0 , -3 , 8 , 7 , 3 , 9 , 4 , 2 , 5 , 10 , 6
        };
        int size = arr.length;
        // Before shuffling  array elements
        System.out.println(" Initial array elements");
        display(arr, size);
        System.out.println(" After Shuffle array elements");
        shuffleElement(arr, size);
        display(arr, size);
        shuffleElement(arr, size);
        display(arr, size);
        shuffleElement(arr, size);
        display(arr, size);
    }
}

Output

 Initial array elements
  1  0  -3  8  7  3  9  4  2  5  10  6
 After Shuffle array elements
  2  8  0  4  7  3  6  10  9  5  1  -3
  3  10  6  7  4  2  1  9  0  8  5  -3
  2  7  6  5  -3  0  10  9  3  4  8  1

The result can be different result because it is based on random shuffling. Let's look at an example in the image below.
