Java Program to shuffle a given array

In this program, we are going to share Java Program to shuffle a given array with the output. If you are a Java beginner and want to start learning the Java programming, then keep your close attention in this tutorial as I am going to share how to write a java program to shuffle a given array.

Java Program to shuffle a given array with the output

Copy the below Java program and execute it with the help of Javac compiler. At the end of this program, We have shared the output of this program.

import java.util.Random;
import java.util.Arrays;
public class ShuffleRand 
{
    static void randomize( int arr[], int n)
    {
        Random r = new Random();        
        for (int i = n-1; i > 0; i--) {
             
            int j = r.nextInt(i);
             
            int temp = arr[i];
            arr[i] = arr[j];
            arr[j] = temp;
        }
        System.out.println(Arrays.toString(arr));
    }
     
    public static void main(String[] args) 
    {
         
         int[] arr = {1, 2, 3, 4, 5, 6, 7, 8};
         int n = arr.length;
         randomize (arr, n);
    }
}

import java.util.Random;

import java.util.Arrays;

public class ShuffleRand

{

static void randomize( int arr[], int n)

{

Random r = new Random();

for (int i = n-1; i > 0; i--) {

int j = r.nextInt(i);

int temp = arr[i];

arr[i] = arr[j];

arr[j] = temp;

}

System.out.println(Arrays.toString(arr));

}

public static void main(String[] args)

{

int[] arr = {1, 2, 3, 4, 5, 6, 7, 8};

int n = arr.length;

randomize (arr, n);

}

Output:

7 8 4 6 3 1 2 5
