Question

A variable like userNum can store a value like an integer. Extend the given program to print userNum values as indicated.(1) Output the user's input.Enter integer: 4You entered: 4(2) Extend to output the input squared and cubed. Hint: Compute squared as userNum * userNum. (Submit for 2 points, so 4 points total).Enter integer: 4You entered: 44 squared is 16 And 4 cubed is 64!! (3) Extend to get a second user input into userNum2. Output sum and product. (Submit for 1 point, so 5 points total).Enter integer: 4You entered: 44 squared is 16 And 4 cubed is 64!!Enter another integer: 54 + 5 is 94 * 5 is 20LABACTIVITY1.16.1: Basic output with variables (Java)0 / 5OutputWithVars.javaLoad default template...import java.util.Scanner;public class OutputWithVars {public static void main(String[] args) {Scanner scnr = new Scanner(System.in);int userNum = 0;System.out.println("Enter integer: ");userNum = scnr.nextInt(); return;}}import java.util.Scanner;public class OutputWithVars {public static void main(String[] args) {Scanner scnr = new Scanner(System.in);int userNum = 0;System.out.println("Enter integer: ");userNum = scnr.nextInt();return;}}Develop modeSubmit modeRun your program as often as you'd like, before submitting for grading.

Answer:

The program in Java is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

 int userNum;

 Scanner input = new Scanner(System.in);

 System.out.print("Enter integer: ");

 userNum = input.nextInt();

 System.out.println("You entered "+userNum);

 System.out.println(userNum+" squared is "+(userNum*userNum));

 System.out.println(userNum+" cubed is "+(userNum*userNum*userNum));

 int userNum2;

 System.out.print("Enter another integer: ");

 userNum2 = input.nextInt();

 int sum= userNum + userNum2; int product = userNum2 * userNum;

 System.out.println(userNum+" + "+userNum2+" = "+sum);

 System.out.println(userNum+" * "+userNum2+" = "+product); } }

Explanation:

This declares userNum

 int userNum;

 Scanner input = new Scanner(System.in);

This prompts the user for input

 System.out.print("Enter integer: ");

This gets user input from the user

 userNum = input.nextInt();

Number (1) is implemented here

 System.out.println("You entered "+userNum);

Number (2) is implemented here

 System.out.println(userNum+" squared is "+(userNum*userNum));

 System.out.println(userNum+" cubed is "+(userNum*userNum*userNum));

This declares another variable userNum2

 int userNum2;

This prompts the user for another input

 System.out.print("Enter another integer: ");

This gets user input from the user

 userNum2 = input.nextInt();

This calculates the sum and the product

 int sum= userNum + userNum2; int product = userNum2 * userNum;

Number (3) is implemented here

 System.out.println(userNum+" + "+userNum2+" = "+sum);

 System.out.println(userNum+" * "+userNum2+" = "+product);
