Question

5.13 LAB: Output numbers in reverse Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a space, including the last one. Assume that the list will always contain fewer than 20 integers. Ex: If the input is: 5 2 4 6 8 10 the output is: 10 8 6 4 2 To achieve the above, first read the integers into an array. Then output the array in reverse.
How do I add the space that this Zybooks code keeps asking me to add?

Answer 1

import java.util.Scanner;

public class LabProgram {

    public static void main(String[] args) {
        Scanner scnr = new Scanner(System.in);
        int numElements = scnr.nextInt();
        int[] userList = new int[numElements];
        for (int i = 0; i < userList.length; ++i) {
            userList[i] = scnr.nextInt();
        }
        for (int i = numElements - 1; i >= 0; --i) {
            System.out.print(userList[i] + " ");
        }
        System.out.println();
    }
}

Answer 2

if (i==0) {

System.out.println();

}
