Question

Chapter 21.2, Problem 21.2.7CP

Program Plan Intro

Program:

//import util package

import java.util.;

//class definition

public class Test {

// main method

public static void main(String[] args) {

//Create a new Set set1 ofLinkedHash Set type

LinkedHashSet<String> set1 = new LinkedHashSet<>();

/ add NewYork element into the set using the add() method /

set1.add("New York");

/Create a new set set2 which equals set1 /

LinkedHashSet<String> set2 = set1;

//clone set1 and assign it a new set set2

LinkedHashSet<String> set3 =

(LinkedHashSet<String>)(set1.clone());

//add Atlanta to the set1

set1.add("Atlanta");

//print each set

System.out.println("set1 is " + set1);

System.out.println("set2 is " + set2);

System.out.println("set3 is " + set3);

/ Print each element present in set 1 using the ForEach() method */

set1.forEach(e -> System.out.print(e + " "));

}

using System; class Program { publicstaticvoid Main(string[] args) { int number = 1,i; while (number <= 88) { Console.WriteLine(number); number = number + 2; { Random r = new Random(); int[] randNo=newint[3]; for(i=0;i<3;i++) { randNo[i]= r.Next(1,88) Console.WriteLine("Random Number between 1 and 88 is "+randNo); } } } } } how can this program be fixed to choose three random numbers in C# between 1-88 instead of just one random number?
