Question

LunchOrder

The goal of this is to:

Create an object which supports the Comparable, Serializable, and Cloneable interfaces.

Be able to sort an ArrayList of objects implementing the Comparable interface.

Be able to clone LunchOrder objects and to understand the difference between a reference copy and a “full” copy.

Explore how to save and restore Objects to/from a file.

Create and use multiple Iterators.

ArrayList

Modify the ArrayList class in staticArray:

implement Iterable<T>

private Iterator class

implement Serializable

add clear() : set all elements to null and reset the next field.

implement a sort() method

selection sort (Sorting method will fall later in the semester)

LunchOrder

Create a LunchOrder class with the following fields:

String name

int orderNumber

int number of burgers

int number of fries

int number of sodas

Date created; reference to a java.util.Date object.

static int nextOrderNumber

static int comparisonMethod

In addition, define constants for the cost of a burger (2.75), fries (.75), and soda (1.50).

Note: all fields should be defined as private or protected unless there is a good reason to do otherwise.

The LunchOrder will implement the following interfaces: Comparable, Cloneable, and Serializable.

We will be able to support sorting LunchOrders based on 3 different criteria: order number, customer’s name, and cost of the order. To do so, the LunchOrder will need the following constants to support different ways to compare LunchOrders:

based on ID

based on customer’s name

based on the cost of an order

LunchOrder methods

double computeOrderCost(): you will be passed two doubles for the tax and tip rates. Compute the cost based on the Cost per item, the number of items, the tax and tip based on the subtotal.

int compareTo(): LunchOrder objects will be compared based on the comparison indicator (ID, name, cost of order). This method is defined in the Comparable interface.

clone(): copy of item using the Object’s clone method and then make of a copy of the Date object reference by the dateCreated field. This method is defined in the Cloneable interface.

toString(): display the name, id, number of items, order cost, and the date Created field.

a static method to display the header for the toString() method.

accessors where needed.

Restaurant application.

Modify Restaurant.java, this is the application code.

Complete the following test methods:

testIterators(): create 2 Iterators. Display the first 3 orders of the 1st iterator, then display all the orders of the 2nd iterator, and then display the rest of the elements with the 1st iterators. This is to show the independence of each iterator.

testCloneMethod(): first implement the LunchOrder’s clone method to just call the Object’s clone method. After cloning a specific object, verify when you modify the Date field (using getTime() and setTime()), it changes both the original and cloned objects. Then modify the LunchOrder’s clone method so that it creates a new Date object with the same value of the original order. Verify when you modify the clone’s Date field, it does not change the original object’s Date field.

In addition, you will modify code within the mainMenu() to:

save and restore all LunchOrder objects to a file called lunchOrder.dat

save and restore the ArrayList of LunchOrder objects to a filed called arrayLunchOrderObjects.dat.

Display of Application:

1 ..create new Array of LunchOrders

2 ..add 10 entries to the Array of LunchOrders

3 ..display array

4 ..sort on order#

5 ..sort on customer

6 ..sort on cost

7 ..save individual objects to a file

8 ..restore individual objects from a from file

9 ..save ArrayList object to a file

10 ..restore ArrayList object from a from file

11 ..test clone

12 ..test iterators

20 ..exit

1 ..create new Array of LunchOrders

2 ..add 10 entries to the Array of LunchOrders

3 ..display array

4 ..sort on order#

5 ..sort on customer

6 ..sort on cost

7 ..save individual objects to a file

8 ..restore individual objects from a from file

9 ..save ArrayList object to a file

10 ..restore ArrayList object from a from file

11 ..test clone

12 ..test iterators

20 ..exit

NOTE: We created 10 LunchOrders after we created the array. Each element is displayed via a call to the toString() method. The static method, getHdr() returns the corresponding header for the display.

ArrayList is restored from a file, therefore we go back to the original 10 items we saved in the order that they were in (based on order number).

Note: you need to repeat the save/restore saving the ArrayList as an object. 1 call to writeObject, as opposed to 10 calls above.
