Question
Below is my ItemToPurchase.java that needs modified.
7.20 Ch 7 Program: Online shopping cart (continued) (Java) Note: Creating multiple Scanner objects for the same input stream yields unexpected behavior. Thus, good practice is to use a single Scanner object for reading input from System.in. That Scanner object can be passed as an argument to any methods that read input. This program extends the earlier Online shopping cart" program. (Consider first saving your earlier program (1) Extend the Item ToPurchase class per the following specifications Private fields string itemDescription - Initialized in default constructor to none . Parameterized constructor to assign item name, item description, item price, and item quantity (default values of 0). (1 pt) Public member methods setDescription mutator & getDescription0 accessor (2 pts) printltemCost0 Outputs the item name followed by the quantity, price, and subtotal printitemDescription0-Outputs the item name and description Ex. of printitemCost0 output: Bottled Water 10 @ $1 = $10 Ex. of printltemDescription0 output: Bottled Water Deer Park, 12 oz.Explanation / Answer
