Question

Basic output with variables (Java). (1) Output the user’s input Enter integer: 4 You entered: 4. (2) Extend to output the input squared and cubed. HINT: Compute squared as userNum * userNum (Submit for 2 points, so a total of 4 points). Enter integer: 4 You entered: 4, 4 squared is 16 and 4 cubed is 64!! (3) Extend to get a second user input userNum2. Output sum and product. Enter integer: 4 You entered: 4, 4 squared is 16 and 4 cubed is 64!! Enter another integer: 5, 4+5 is 9 and 4 multiplied by 5 is 20. ​

Answer 1

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

// Read first integer

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

int userNum = sc.nextInt();

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

// Compute squared and cubed

int squared = userNum * userNum;

int cubed = userNum * userNum * userNum;

System.out.println(userNum + " squared is " + squared + " and " + userNum + " cubed is " + cubed + "!!");

// Read second integer

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

int userNum2 = sc.nextInt();

System.out.println(userNum + "+" + userNum2 + " is " + (userNum + userNum2) + " and " + userNum + " multiplied by " + userNum2 + " is " + (userNum * userNum2));
