Question

"Using the printf method, print the values of the integer variables bottles and cans so that the output looks like this: Bottles: 8 Cans: 24 The numbers to the right should line up. (You may assume that the numbers have at most 8 digits.)"

Answer 1

Answer:

import java.util.Scanner;

public class Main

{

public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       

       System.out.println("Enter the number of bottles and cans:");

       int numberOfbottles = in.nextInt();

       int numberOfcans = in.nextInt();

       System.out.printf("Bottles: %8d\n", numberOfbottles);

       System.out.printf("Cans:    %8d\n", numberOfcans);

}

}

Explanation:

Ask user to input the number of bottles and cans using Scanner class

Print the results so that the numbers to the right line up (Since we know that the numbers have at most 8 digits, we can use %8d in printf. Also, be aware that how printf statements are written so that the numbers line up)
