Part-1 (Only 20% of your total course grade) E-TechMart store in Oman sells different electronics products such as Smart Devices, Home Appliances and Games. The store Management requires an automated software to keep track of items in stock and prices. You as a software designer and developer are asked to develop a system for the store. The first task you should carry out is to design and code a class related to stocked Items. You can name this class as Item_in_Stock. The class should consist of the following: A data member Item_code to store an item code eg. MIO, a data member to store item name, a data member to store item description, a data member to store quantity of items in stock and a data member item_price to store price of an item. You must use the appropriate data types and access specifier for each data member . Class should have a constructor that initialises class objects with specified item_code, quantity and price of items. . Getter and setters methods for all the data members including getItemCato method which returns "Unknown Item Category": getItemName() method which returns the "Unknown Item Name" and getItem Description which retums "Unknown Item Description". These methods will be overridden in later tasks of the assignment to set and display information related to specific items. An add_Item method to add items in stock with a check that item stock does not exceed 120. An appropriate message should be displayed if inserted item exceeds the limit. An item_Sell member method to sell items, method should ask for quantity of selling item and then reduces the stock level accordingly. A tax_on_Item method gives tax on items (Tax is fixed at 5%) A method to set item price without tax and get method to get item price both with and without tax A method named get_Item_Details() that provides Item code, Item Category, Item name, Item description, quantity in stock, and price with and without tax. Task 1.1 Graphically represent above mentioned class in UML by drawing class diagram. Task 1.2. Implementation of the class using Java language. Write a program called Stocked_Item with main () method to test the Item_in_Stock class. Testing is an integral part of development. Write suitable test cases in the given format below for your class. Test Case Purpose Expected result Example OUTPUT: Creating a stock with 10 units Unknown item, price R.O 100 per item, and item code M10 Printing item stock information: Item Category: Unknown Item Category Item Name: Unknown Item Name Description: Unknown Item Description StockCode: M10 Price Without Tax: R.O 100 Price With Tax: R.O 105 Total quantity in store: 10 Adding 10 more items Printing item stock information: Item Category: Unknown Item Category Item Name: Unknown Item Name Description: Unknown Item Description StockCode: M10 Price Without Tax: R. O 100 Price With Tax: R.O 105 Total quantity in store: 20 Sold 2 items Printing item stock information: Item Category: Unknown Item Category Item Name: Unknown Item Name Description: Unknown Item Description StockCode: M10 Price Without Tax: R. O 100 Price With Tax: R.O 105 Total quantity in store: 18 Changing price to R.O 120 Printing item stock information: Item Category: Unknown Item Category Item Name: Unknown Item Name Description: Unknown Item Description StockCode: M10 Price Without Tax: R. O 120 Price With Tax: R. O 126 Total quantity in store: 18 Adding 120 more Items The error: Item stock must not exceed 120 items Part-11 (Only 30% of your total course grade) In this part of the course work, you are required to design and implement a class called Sony TV with instance variables specific to this type of items, a constructor with parameters which initialises class data members and invokes the Item_in_Stock constructor when it is invoked using inheritance concept in java and initialises data members of Item_in_stock class as well. This class should be designed and implemented in a way that it overrides getItemCategory that returns the category of the item, getitemName that returns Sony TV and getItemDescription() that returns "Sony Smart TV 45"". The Class should also override the get_item_details() method to display the complete details of an item. Task 2.1. Re-draw UML class diagram which was drawn in part 1 of the course work with this new class "Sony_TV". Relationships should also be represented. Task 2.2. Implement a class called Item_check with a main method to test Sony TV class by defining object of the class and invoking methods. Testing is an integral part of development. Write suitable test cases in the given format below for your classes. Test Case Purpose Expected result OUTPUT: Refer to output in part 1. item category, item name and item description should be according to the Items
