Question

TO DO in JAVA: The program that runs is TrackInsurance. Open this up and add five instances of your ArtInsurance class at the noted location in the main method. Use whatever data you like.

TrackInsurance(below)

package itp120mod6;

import java.util.*;

public class TrackInsurance extends Object {

public static Scanner scan = new Scanner(System.in);

// method that runs first

public static void main(String[] args) throws Exception {

// make an ArrayList of customers and insurance policies

ArrayList cust = new ArrayList();

// note - the ArrayList below can hold Insurance objects

// but with inheritance, that includes Auto, Health, Life and Art

ArrayList ins = new ArrayList();

// create some fake customers (used for testing the program)

Customer c = new Customer("Duck", "Donald");

Customer c1 = new Customer("Mouse", "Minnie");

Customer c2 = new Customer("Mouse", "Mickey");

// add the customers to the array list

cust.add(c2);

cust.add(c1);

cust.add(c);

// make and add some insurance policies to the ArrayList

ins.add(new AutoInsurance(c, 2));

ins.add(new AutoInsurance(c1, 3));

/*ins.add(new HealthInsurance(c, 5));

ins.add(new HealthInsurance(c2, 1));
