I need your help:Using Java

You are to write a program to simulate the counter activity at a deli. The actions that can be taken are given by the String[] in the DeliCounter class provided. Only the major components of the classes you are to write will be provided; other requirements will have to be derived and provided based on implied program behavior.

Write the following classes

MenuItem

Write an abstract class MenuItem. The delis menu is, simply, a collection of MenuItem objects. All MenuItems have a name and a price. Well assume that all names are a single word (no embedded spaces) and all prices can be represented as a double value. MenuItem has an abstract method, boolean isInventory(). More on inventory below.

PackagedItem

Some items on the delis menu are pre-packaged and considered inventory; bottles of water, cans of soft drinks, bags of chips are examples. These items, in addition to a name and unit price, have a quantity. For example, the deli may have 50 bags of chips on hand. The quantity must be adjusted as items are sold. (We wont worry about restocking for this program.) The owner of the shop wants to know the total value of his packaged inventory items.

PreparedItem

Some items on the delis menu must be prepared for each order. Such items are not considered to be inventory. In addition to a name and price, PreparedItems have a preparation time that is kept in minutes.

Additional Program Capability

Initially, the deli program starts with an empty menu. It should be able to save and restore the menu on demand. It should be able to offer customers the list of items that may be ordered, sell an item, add new items to the menu, and list the current value of the packaged items.

Grading Elements

MenuItem is an abstract class representing any menu item, it contains the isInventory method.

PackagedItem, PreparedItem are classes that represent specific types of menu items, minimize their local class members, and exploit their superclass as much as possible.

DeliCounter program supports all user operations.

All class members are marked public or private, as appropriate. Code follows the Java naming conventions, is in the default package, submission is a single zip file with no directories.
