This is code I am working with for a class, and I am unable to get the desired Output required.  I am attaching screenshots of the output that needs to take place.  please comment on what you are doing so I can learn, I am still a novice at java.  Also,the program needs to be able to run exactly as the instructor says.

package asi7123;

import java.util.*;

public class Asi7123 {

public static void main(String[] args) {

Scanner keyboard = new Scanner(;

String name;

int age;

String answer;

Person person;

do {

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

name = keyboard.nextLine();

while ("".equals(name)) {

System.out.println("ERROR: Please enter a name");

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

name = keyboard.nextLine();


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

age = keyboard.nextLine();

// integer lineEntered;

// lineEntered = keyboard.nextLine();

// age = Integer.parseInt(lineEntered);


while (age System.out.println("ERROR: age must be 0 or higher");

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

//lineEntered = keyboard.nextLine();

//age = Integer.parseInt(lineEntered);


person = new Person(); = name;

person.age = age;


System.out.print("Another (Y/N): ");

answer = keyboard.nextLine();

if (!"Y".equals(answer)) {

System.out.print("ERROR: Enter Y or N: ");

answer = keyboard.nextLine();


if (!"N".equals(answer)) {

System.out.print("ERROR: Enter Y or N: ");

answer = keyboard.nextLine();

} while (answer.equals("Y"));

System.out.println("You entered " + person.size() + " names:");

for (Person elt : people) {
