public static void main(String[] args)

{

Scanner scnr = new Scanner(System.in);

String item ="";

int price = 0;

int quantity = 0;

int item1Cost = 0;

int item2Cost = 0;

ItemToPurchase firstItem = new ItemToPurchase(item, price, quantity);

ItemToPurchase secondItem = new ItemToPurchase(item, price, quantity);

System.out.println("Please enter information for two items.");

System.out.println("Item 1: ");

System.out.println("Enter the item name: ");

item = scnr.nextLine();

firstItem.setItemName( item);

System.out.println("Enter the price: ");

price = scnr.nextInt();

firstItem.setItemPrice(price);

System.out.println("Enter the quantity: ");

quantity = scnr.nextInt();

firstItem.setItemQuantity(quantity);

System.out.println("Item 2: ");

scnr.nextLine();

System.out.println("Enter the second item name: ");

item = scnr.nextLine();

secondItem.setItemName( item);

System.out.println("Enter the price: ");

price = scnr.nextInt();

secondItem.setItemPrice(price);

System.out.println("Enter the quantity: ");

quantity = scnr.nextInt();

secondItem.setItemQuantity(quantity);

System.out.println("Total Cost"); // calculating total cost

item1Cost = firstItem.getItemQuantity() * firstItem.getItemPrice();

System.out.print( firstItem.getItemName());

System.out.print(" " + firstItem.getItemQuantity());

System.out.print(" @ $" + firstItem.getItemPrice());

System.out.print(" = $" + item1Cost);

System.out.println("");

item2Cost = secondItem.getItemQuantity() * secondItem.getItemPrice();

System.out.print( secondItem.getItemName());

System.out.print(" " + secondItem.getItemQuantity());

System.out.print(" @ $" + secondItem.getItemPrice());

System.out.print(" = $" + item2Cost);

System.out.println("");

System.out.print("Total Cost = $" + (item1Cost+item2Cost));

}

}
