Question

for the following JAVA program

Deals of the grocery store. The infomations on the flyer:

1.By buying  items under $250, the client will get a  10% off in total and get double point

2.By buying items between $250-500 (both included),the client will get 15% off in total and get double points.

3.By buying items over 500, the client will get 20% off in total and get triple points.

Fish  is not included in the total discount price.

The calculation of the points is the following:

You need to have a membership in order to get the points

double points = 2*total price (fish included)

triple points = 3*total price ( fish included).

The total of the points will be an integer that is rounded up. (you can use Math.round())

_Item No.	Item Name	Price per item
1	Vegetables	$26.99
2	Cheese	$22.99
3	Eggs	$13.99
4	Meat	$56.99
5	Fish	$38.99

Example :

Please enter the quantities for each item in the list? 1 2 0 1 1

Do you have the membership of the store? (Yes or no) Yes

The total of your shopping is $155.954. You accumulated 312 points for your purchase today.

Thank you

Program:

import java.util.Scanner;

class GroceryStore
{
   //main method
   public static void main(String[] args)
   {
       //create instance
   Scanner kb = new Scanner(System.in);
   //array of prices
   double itemPrice[] = {26.99, 22.99, 13.99, 56.99, 38.99};
  
   int n = itemPrice.length;
   //prompt to enter the quantities for each item in the list
   System.out.print ("Please enter the quantities for each item in the list? ");
  
   double totalCost = 0;
   double fishAmount = 0;
   for(int i=0; i<n; i++)
   {
       //read the quantities for each item in the list
       int items = Integer.parseInt(kb.next());
       //check for fish item
       if(i==4)
           fishAmount = itemPrice[i]*items;
       else
           totalCost = totalCost + itemPrice[i]*items;
   }
       
        //prompt and read if yo have membership of the store
        System.out.print ("Do you have the membership of the store? (Yes or no) ");
   String res = kb.next();
  
   //calculate off amount
   double off;
   if(totalCost<250)
       off = totalCost*0.1;
   else if(totalCost<=500)
       off = totalCost*0.15;
   else
       off = totalCost*0.2;
  
   totalCost = totalCost + fishAmount - off;
  
   //calculate points
   long points = 0;
   if(res.equalsIgnoreCase("yes"))
   {
       if(totalCost<=500)
           points = Math.round(totalCost*2);
           else
           points = Math.round(totalCost*3);
   }
  
   //display the totalCost and points
   System.out.print ("The total of your shopping is $" + totalCost + ".");
   if(res.equalsIgnoreCase("yes"))
       System.out.println ("You accumulated " + points + " points for your purchase today.");
   System.out.println ("Thank you");
   }
}

Output:

Please enter the quantities for each item in the list? 1 2 0 1 1
Do you have the membership of the store? (Yes or no) yes
The total of your shopping is $155.954.You accumulated 312 points for your purchase today.
