Answer 1

import java.util.Scanner;

public class Listing {

    private String name;
    private int age;

    public Listing() {
        name = " ";
        age = 0;
    }

    public Listing(String name, int age) {
        this.name = name;
        this.age = age;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return "name='" + name + '\'' + ", age=" + age;
    }

    public void input() {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter name: ");
        name = in.nextLine();
        System.out.print("Enter age: ");
        age = Integer.parseInt(in.nextLine());
    }
}

class ListingTest {

    public static void main(String[] args) {
        Listing[] listings = new Listing[3];
        for (int i = 0; i < listings.length; i++) {
            listings[i] = new Listing();
            listings[i].input();
        }
        for (int i = listings.length-1; i >= 0; i--) {
            System.out.println(listings[i]);
        }
    }
}
