import java.util.*;
public class MyClass {
    public static void main(String args[]) {
    int[] array = { 1, 2, 3, 4, 5, 6, 7 };
    Random rand = new Random();
    for (int i = 0; i < array.length; i++) {
     int randomIndexToSwap = rand.nextInt(array.length);
     int temp = array[randomIndexToSwap];
     array[randomIndexToSwap] = array[i];
     array[i] = temp;
    }
    
    System.out.println(Arrays.toString(array));
    }
}

In this program array element place can't be same.

Output.

[2, 6, 4, 1, 7, 3, 5]
