Question

In Java:

(1) Create two files to submit:

• ItemToBuy.java - Class definition
• ShoppingCartDriver.java - Contains main() method

Build the ItemToBuy class with the following specifications:

• Private fields
  • String itemName - Initialized in the nor-arg constructor to "none"
  • int itemPrice - Initialized in default constructor to 0
  • int itemQuantity - Initialized in default constructor to 0
• No-arg Constructor (set the String instance field to "none")
• Public member methods (mutators & accessors)
  • setName() & getName()
  • setPrice() & getPrice()
  • setQuantity() & getQuantity()
  • toString()

(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.

Ex:

Item 1

Item = Chocolate Chips, Price = 3, Quantity =  1

Item 2

Item = Bottled Water, Price = 1, Quantity = 10

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

TOTAL COST Chocolate Chips 1 @ $3 = $3

Bottled Water 10 @ $1 = $10

Total: $13

Answer 1

package items;
import java.util.*;
public class ItemToBuy//public class
{
    public String itemName ;//data members
    public int itemPrice;
    public int itemQuantity;
    Scanner sc=new Scanner(System.in);
    public ItemToBuy()//functions
    {
        itemName="none";
        itemPrice=0;
        itemQuantity=0;
    }
    public void setName()
    {
        
        itemName=sc.nextLine();
    }
    public String getname()
    {
        return itemName;
    }
    public void setprice()
    {   
      
        itemPrice=sc.nextInt();
    }
    public int getprice()
    {
        return itemPrice;
    }
    public void setquantity()
    {
        itemQuantity=sc.nextInt();
    }


    public int getquantity()
    {
        return itemQuantity;
    }
}

save this file make it a packge by

javac -d . ItemToBuy.java

this above command in command prompt

import items.ItemToBuy;//imporing the class 
class ShoppingCartDriver
{
    public static void main(String[] args) {
        ItemToBuy obj=new ItemToBuy();//making the 2 objects
        ItemToBuy obj1=new ItemToBuy();
        System.out.println("item 1");//input from the user
        System.out.println("enter name");
        obj.setName();
        System.out.println("enter price");
        obj.setprice();
        System.out.println("enter quantity");
        obj.setquantity();
        System.out.println("item 2");
        System.out.println("enter name");
        obj1.setName();
        System.out.println("enter price");
        obj1.setprice();
        System.out.println("enter quantity");
        obj1.setquantity();
        System.out.println("Total cost"+obj.getname()+obj.getquantity()+"@ $"+obj.getprice());
        int i1=obj.getprice()*obj.getquantity();
        System.out.println(i1);
        System.out.println("Total cost"+obj1.getname()+obj1.getquantity()+"@ $"+obj1.getprice());
        int i2=obj1.getprice()*obj1.getquantity();
        System.out.println(i2);
        int total=i1+i2;//total price calculation
        System.out.println("total= $"+total);
        



    }
}

output:

item 1
enter name
Chocolate Chips
enter price
1
enter quantity
3
item 2
enter name
Bottled Water
enter price
1
enter quantity
3
Total costChocolate Chips3@ $1
3
Total costBottled Water3@ $1

total= $6
