Create a list with 5 numbers and find the smallest and largest number in the list and also the sum and product of the numbers in the list, Additionally, find the sum and product of the largest and the smallest number.

Explanation:

The following code is written in Java. It creates 5 random integers and saves them to a list called myList. Then it loops through that list and checks each one until the largest and smallest values are obtained. Finally, it uses these values to calculate the sums and products as requested. The program has been tested and the output can be seen in the attached image below.

import java.util.ArrayList;

import java.util.Arrays;

import java.util.Random;

import java.util.Scanner;

class {

   public static void main(String[] args) {

       Random rand = new Random();

       ArrayList<Integer> myList = new ArrayList<>();

       for (int i = 0; i< 5; i++) {

           int mynum = rand.nextInt(20);

           myList.add(mynum);

       }

       int largest = myList.get(0);

       int smallest = myList.get(0);

       int sum = 0;

       int product = 1;

       int sumLargestandSmallest, productLargestandSmallest;

       for (int x : myList) {

           if (x > largest) {

               largest = x;

           }

           if (x < smallest) {

               smallest = x;

           }

           sum += x;

           product *= x;

       }

       sumLargestandSmallest = largest + smallest;

       productLargestandSmallest = largest * smallest;

       System.out.println("List" + Arrays.toString(myList.toArray()));

       System.out.println("Smallest: " + smallest);

       System.out.println("Largest: " + largest);

       System.out.println("Sum: " + sum);

       System.out.println("Product: " + product);

       System.out.println("Sum of Smallest and Largest: " + sumLargestandSmallest);

       System.out.println("Product of Smallest and Largest: " + productLargestandSmallest);

   }

}

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).
