Question

I need this code in java.

Task

(1) Create two files to submit:

• ItemToPurchase.java - Class definition
• ShoppingCartPrinter.java - Contains main() method

Build the ItemToPurchase class with the following specifications:

• Private fields
  • String itemName - Initialized in default constructor to "none"
  • int itemPrice - Initialized in default constructor to 0
  • int itemQuantity - Initialized in default constructor to 0
• Default constructor
• Public member methods (mutators & accessors)
  • setName() & getName() (2 pts)
  • setPrice() & getPrice() (2 pts)
  • setQuantity() & getQuantity() (2 pts)

(2) In main(), prompt the user for two items and create two objects of the ItemToPurchase class. Before prompting for the second item, call scnr.nextLine(); to allow the user to input a new string. (2 pts)

Ex:

Item 1
Enter the item name:
Chocolate Chips
Enter the item price:
3
Enter the item quantity:
1

Item 2
Enter the item name:
Bottled Water
Enter the item price:
1
Enter the item quantity:
10

(3) Add the costs of the two items together and output the total cost. (2 pts)

Ex:

TOTAL COST
Chocolate Chips 1 @ $3 = $3
Bottled Water 10 @ $1 = $10

Total: $13

This is the given code so far:

import java.util.Scanner;

public class ShoppingCartPrinter {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int i = 0;
String productName;
int productPrice = 0;
int productQuantity = 0;
int cartTotal = 0;
  
// TODO Create new item1 and new item2

// Prompt for item 1 details from user, create itemToPurchase object
System.out.println("Item 1");
System.out.println("Enter the item name:");
productName = scnr.nextLine();
  
System.out.println("Enter the item price:");
productPrice = scnr.nextInt();
  
System.out.println("Enter the item quantity:");
productQuantity = scnr.nextInt();
System.out.println("");
  
// TODO: Set item1 fields here
  

// Promptr for item 2 details from user, create itemToPurchase object
System.out.println("Item 2");
System.out.println("Enter the item name:");
scnr.nextLine(); // DO NOT OMIT THIS LINE
productName = scnr.nextLine();
  
System.out.println("Enter the item price:");
productPrice = scnr.nextInt();
  
System.out.println("Enter the item quantity:");
productQuantity = scnr.nextInt();
System.out.println("");
  
// TODO set item2 here

  
// Add costs of two items and print total
cartTotal = (item1.getPrice() * item1.getQuantity()) +
(item2.getPrice() * item2.getQuantity());
System.out.println("TOTAL COST");
System.out.println(item1.getName() + " " + item1.getQuantity() +
" @ $" + item1.getPrice() + " = $" +
(item1.getPrice() * item1.getQuantity()));
System.out.println(item2.getName() + " " + item2.getQuantity() +
" @ $" + item2.getPrice() + " = $" +
(item2.getPrice() * item2.getQuantity()));
System.out.println("");
System.out.println("Total: $" + cartTotal);
  
return;
}
}

ItemToPurchase.java :

//Java class
public class ItemToPurchase {
   //private variables
   private String itemName;
   private int itemPrice;
   private int itemQuantity;
   //Constructor
   public ItemToPurchase() {
       itemName = "none";
       itemPrice = 0;
       itemQuantity = 0;
   }
   //getter method
   public String getName() {
       return itemName;
   }
   //setter method
   public void setName(String in) {
       this.itemName = in;
   }
   public int getPrice() {
       return itemPrice;
   }

   public void setPrice(int ip) {
       this.itemPrice = ip;
   }

   public int getQuantity() {
       return itemQuantity;
   }

   public void setQuantity(int iq) {
       this.itemQuantity = iq;
   }

}

ShoppingCartPrinter.java :

package sample;

import java.util.Scanner;//java class

public class ShoppingCartPrinter {
   public static void main(String[] args) {
       Scanner scnr = new Scanner(System.in);
       int i = 0;
       String productName;
       int productPrice = 0;
       int productQuantity = 0;
       int cartTotal = 0;

// TODO Create new item1 and new item2
       ItemToPurchase item1 = new ItemToPurchase();
       ItemToPurchase item2 = new ItemToPurchase();
// Prompt for item 1 details from user, create itemToPurchase object
       System.out.println("Item 1");
       System.out.println("Enter the item name:");
       productName = scnr.nextLine();

       System.out.println("Enter the item price:");
       productPrice = scnr.nextInt();

       System.out.println("Enter the item quantity:");
       productQuantity = scnr.nextInt();
       System.out.println("");

// TODO: Set item1 fields here
       item1.setName(productName);
       item1.setPrice(productPrice);
       item1.setQuantity(productQuantity);
// Promptr for item 2 details from user, create itemToPurchase object
       System.out.println("Item 2");
       System.out.println("Enter the item name:");
       scnr.nextLine(); // DO NOT OMIT THIS LINE
       productName = scnr.nextLine();

       System.out.println("Enter the item price:");
       productPrice = scnr.nextInt();

       System.out.println("Enter the item quantity:");
       productQuantity = scnr.nextInt();
       System.out.println("");

// TODO set item2 here
       item2.setName(productName);
       item2.setPrice(productPrice);
       item2.setQuantity(productQuantity);
// Add costs of two items and print total
       cartTotal = (item1.getPrice() * item1.getQuantity()) + (item2.getPrice() * item2.getQuantity());
       System.out.println("TOTAL COST");
       System.out.println(item1.getName() + " " + item1.getQuantity() + " @ $" + item1.getPrice() + " = $"
               + (item1.getPrice() * item1.getQuantity()));
       System.out.println(item2.getName() + " " + item2.getQuantity() + " @ $" + item2.getPrice() + " = $"
               + (item2.getPrice() * item2.getQuantity()));
       System.out.println("");
       System.out.println("Total: $" + cartTotal);

       return;
   }
}
