I am creating a Inventory in Java. It needs the following things. A Salable Class, Shopping Cart class, and Store Front class (main program). In the main program I need to hardcode different products in a array so that I can add it to the cart and checkout.. Each Salable Product should have a name, a description, a price and a quantity. So two strings and two ints. So far I have created the different calluses and hard coded an array list. But I need to allow the user to choose a number for an option. For example System.out.println(" (1) to display inventory (2) to add a inventory to cart (3) to checkout); I need something like that but am having trouble with adding and ckecouet methods. Also my display inventory comes out null.
