Chapter 3, Problem 22C

Explanation of Solution

Implementation of the shuffle() method:

// Define the shuffle() method

public static void shuffle(int[] arr)

{

// Declare variable to assign the array length

int n = arr.length;

// Create an object for Random class

Random r = new Random();

/* Call nextInt() method using "r" Random object to return the next pseudorandom integer value */

r.nextInt();

// Loop executes until array length

for (int i = 0; i < n; i++)

{

/* Call nextInt() method by passing "n-i" to return the next pseudorandom integer value in range from 0 to "n-i" and add the result with "i" and then assign it */

int j = i + r.nextInt(n - i);

/*Declare temporary variable to hold the array elements...
