here is my running project from the beginning to now. I have chosen to use a dvd inventory: I need to get caught up. -Choose a product that lends itself to an inventory (for example, products at yourworkplace, office supplies, music CDs, DVD movies, or software). Create a product class that holds the item number, the name of the product, the numberof units in stock, and the price of each unit. Create a Java application that displays the product number, the name of the product, thenumber of units in stock, the price of each unit, and the value of the inventory (thenumber of units in stock multiplied by the price of each unit). Pay attention to the goodprogramming practices in the text to ensure your source code is readable and welldocumented. -Modify the Inventory Program so the application can handle multiple items. Use an arrayto store the items. The output should display the information one product at a time,including the item number, the name of the product, the number of units in stock, theprice of each unit, and the value of the inventory of that product. In addition, the outputshould display the value of the entire inventory. -Modify the Inventory Program by creating a subclass of the product class that uses oneadditional unique feature of the product you chose (for the DVDs subclass, you could usemovie title, for example). In the subclass, create a method to calculate the value of theinventory of a product with the same name as the method previously created for theproduct class. The subclass method should also add a 5% restocking fee to the value ofthe inventory of that product. Modify the output to display this additional feature you have chosen and the restockingfee. -Modify the Inventory Program to use a GUI. The GUI should display the information oneproduct at a time, including the item number, the name of the product, the number ofunits in stock, the price of each unit, and the value of the inventory of that product. Inaddition, the GUI should display the value of the entire inventory, the additional attribute,and the restocking fee.
