        for (int i = 0; i < arr.length; i++) {
            int index = (int) (Math.random() * arr.length);
            int temp = arr[i];
            arr[i] = arr[index];

import java.util.Random;
public class Example {
   public static void main(String[] args) {
      Random rd = new Random(); // creating Random object
      int[] arr = new int[5];
      for (int i = 0; i < arr.length; i++) {
         arr[i] = rd.nextInt(); // storing random integers in an array
         System.out.println(arr[i]); // printing each array element
      }
   }
