I am having some trouble with zybooks. The code works in netbeans.
Here are the directions:
And here is the code im using:
ItemToPurchase.java

System.out.println("OUTPUT SHOPPING CART");
s.printTotal();
}
else if(ch == 'q' || ch == 'Q'){
break;
}
}
}
}
And this is the error im getting in zybooks:
9.15 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 & getDescription() accessor (2 pts) • printltemCost() - Outputs the item name followed by the quantity, price, and subtotal • printitemDescription() - Outputs the item name and description Ex. of printltemCost() output: Bottled Water 10 @ $1 = $10 Ex. of printitemDescription() output: Bottled Water: Deer Park, 12 oz. (2) Create two new files: • Shopping Cart.java - Class definition • Shopping CartManager.java - Contains main() method Build the ShoppingCart class with the following specifications. Note: Some can be method stubs (empty methods initially, to be complete in later steps. • Private fields • String customerName - Initialized in default constructor to 'none • String currentDate - Initialized in default constructor to *January 1, 2016" • ArrayList cartitems • Default constructor • Parameterized constructor which takes the customer name and date as parameters (1 pt) • Public member methods • getCustomerName() accessor (1 pt)Explanation / Answer
Try it out it should work, PROBLEM IS The names, The names of the function should match excatly as ZYBOOKS
F1) FIRST Run in NETBEANS , Then Submit in ZYBOOKS
