Question

Define global variables called highestNum, userInput and sumOfNums and initialize them. In Main call 2 methods: 1) UserData() 2) DisplayResults()
Task #1:In the UserData() method ask the user to give you a number between 9 and 20, exclusive. Validate this input Then, create a loop that will loop THAT amount of times. Inside that loop generate a random number between 1-100. In that loop check each generated number in order to find the highest number generated. Accumulate all numbers to sumOfNums
Task #2: In the displayResults() method print the following: "There were x numbers generated" "the highest number generated is x" "The sum of the numbers is x" "The average of these numbers is x"

Answer 1

Answer:

Explanation:

The following code is written in Java. It creates the two methods as requested using the Scanner and Random built-in classes in Java. Once the loop is completed and the highestNum is calculated, then the displayResults method is called to print out all the information in the correct format. The output of the program can be seen in the attached image below.

import java.util.Random;

import java.util.Scanner;

class Brainly {

   static int highestNum = 0;

   static int userInput;

   static int sumOfNums = 0;

   public static void main(String[] args) {

       userData();

       displayResults();

   }

   private static void userData() {

       Scanner in = new Scanner(System.in);

       Random rand = new Random();

       System.out.println("Enter a number between 9 and 20: ");

       userInput = in.nextInt();

       if ((userInput >= 9) && (userInput <= 20)) {

           for (int i = 0; i < userInput; i++) {

               int num = rand.nextInt(100);

               if (num > highestNum) {

                   highestNum = num;

               }

               sumOfNums += num;

           }

       }

   }

   public static void displayResults() {

       System.out.println("There were " + userInput + " numbers generated");

       System.out.println("The highest number generated is " + highestNum);

       System.out.println("The sum of the numbers is " + sumOfNums);

       int average = sumOfNums / userInput;

       System.out.println("The average of the numbers is " + average);

   }

}
