Java

In this case study, you are tasked with creating an online store application in Java. The store will sell products such as books, electronics, and clothing. Step 1: Define the class structure To start, you will create a class for each type of product the store sells. You'll start with a Book class, Electronics class, and a Clothing class. Each class should have the following attributes: Book: - Title - Author - ISBN - Price - Electronics: Electronics - Name - Brand - Model - Price - Clothing: Clothing - Name - Brand - Size Step 2: Define the class methods Next, you will define the methods for each class. Book: getTitle(): Returns the title of the book. getAuthor(): Returns the author of the book. getISBN(): Returns the ISBN of the book. getPrice(): Returns the price of the book. Electronics: getName(): Returns the name of the electronics item. getBrand(): Returns the brand of the electronics item. getModel(): Returns the model of the electronics item. getPrice(): Returns the price of the electronics item. Clothing: getName(): Returns the name of the clothing item. getBrand(): Returns the brand of the clothing item. getSize(): Returns the size of the clothing item. getPrice(): Returns the price of the clothing item. Step 3: Create instances of the classes Once you have defined the classes and their methods, you can create instances of each class and test them. Book book1 = new Book("The Great Gatsby", "F. Scott Fitzgerald", "123456789", 19.99); Electronics electronics1 = new Electronics("Laptop", "Dell", "Inspiron", 999.99); Clothing clothing1 = new Clothing("T-Shirt", "Nike", "Large", 24.99); System.out.println("Book Title: " + book1.getTitle()); System.out.println("Electronics Name: " + electronics1.getName()); System.out.println("Clothing Name: " + clothing1.getName()); Step 4: Create a store class Finally, you can create a Store class that will hold a list of products. The store class should have the following methods: addProduct(Book aNewBook): Adds a book to the list of book items addProduct(Electronics aNewElectronic): Adds an electronic object to the list of electronic items addProduct(Clothing aNewClothing): Adds a new piece of clothing to the list of clothing item getTotalInventoryValue(): Returns the total value of the products in the store. To test the store class, you can create instances of the Book, Electronics, and Clothing classes and add them to the store. Store store = new Store() store.addProduct(book1); store.addProduct(electronics1); store.addProduct(clothing1); System.out.println("Total Inventory Value: " + store.getTotalInventoryValue())
