Question

Write a program to keep track of the inventory of grocery store.

Write a test program that prompts the user to enter how many items of inventory the store has. After that enter item name, quantity and price of each item in three different arrays called Itemname, Quantity and Price.

Than calculate the Total=Quantity*Price of items in store and FinalTotal of all the items and print in following exact format using array:

Sample run of program:
Enter number of items to store in array: 3
Enter quantity of item: 10
Enter price of item: 5.0
Enter item name: Mouse
Enter quantity of item: 20
Enter price of item: 10.0
Enter item name: Keyboard
Enter quantity of item: 5
Enter price of item: 20.0
Enter item name: Usb
ItemName       Quantity       Unit Price       Total

Mouse       10.00           $5.00           $50.00
Keyboard       20.00           $10.00       $200.00
Usb            5.00           $20.00       $100.00

FinalTotal                               $350.00

Answer 1

The answer to this question is as follows:

The code is as follows:

import java.util.*;
public class MyClass {
public static void main(String args[]) {
int number_of_items;
double quantity,price_per_item,total=0.0;
String item_name;
Scanner sc=new Scanner(System.in);
System.out.print("Enter the number of items to store in array:");
number_of_items=sc.nextInt();
ArrayList<Double> quantity_list = new ArrayList<Double>(number_of_items);
ArrayList<Double> price_list = new ArrayList<Double>(number_of_items);
ArrayList<String> item_list = new ArrayList<String>(number_of_items);
for(int i=0;i<number_of_items;i++)
{
System.out.print("\nEnter quantity of item:");
quantity=sc.nextDouble();
  
System.out.print("\nEnter price of item:");
price_per_item=sc.nextDouble();
  
System.out.print("\nEnter item Name:");
item_name=sc.nextLine();
  
quantity_list.add(quantity);
price_list.add(price_per_item);
item_list.add(item_name);
}
System.out.print("\n ItemName\t\t Quantity\t\t\t Unit Price \tTotal\n");
for (int i=0; i<number_of_items; i++)
{
System.out.print(item_list.get(i)+"\t\t\t");
System.out.print(quantity_list.get(i)+"\t\t\t\t");
System.out.print("$"+price_list.get(i)+"\t\t\t ");
System.out.print("$"+quantity_list.get(i)*price_list.get(i)+"\t\t\t\t");
System.out.println();
total=total+quantity_list.get(i)*price_list.get(i);
}
System.out.print(" FinalTotal\t\t\t$"+total);
}
}
