This code is how to randomize the sequence of numbers. Code: 1 package random.sort; 2 3 import java.util.Arrays; 4 import java.util.Random; 5 6 public class RandomSort { 7 public static int [] generate ( int num) { 8 int [] result = new int [num]; 9 Random rand= new Random(); 10 int i = 0; 11 while (i < num) { 12 int a=rand.nextInt(num); 13 boolean exist= false ; 14 for ( int j = 0; j < i; j++) { 15 if (result[j] == a) { 16 exist= true ; 17 break ; 18 } 19 } 20 if (!exist){ 21 result[i]=a; 22 i++; 23 } 24 } 25 return result; 26 } 27 28 public static void main (String[] args) { 29 //how library work 30 int [] randomIndex=RandomSort. generate (10); 31 System. out .println( " RandomIn...
