Question

Write an application that queries the user for the following information about a stock transaction and then displays the net gain or loss on the transaction.

1. Number of shares bought and sold (this is one number not two)
2. Purchase price per share
3. Purchase commission as a double (for example, 2% commission would be 0.02)
4. Sale price per share
5. Sale commission as a double (for example, 2% commission would be 0.02)

You must allow the user to enter the values. However you can use the following numbers to check your lab

Shares = 1000

Purchase price = $45.2

Purchase commission = 2% or 0.02

Sale price = $46.5

Sale commission = 2% or 0.02

Net loss of $534

import java.util.Scanner;

public class Stock {
   public static void main(String[] args) {
       int sharesOfStock;
       double salePrice;
       double pricePerShare;
       double commissionRate;
       double saleCommision;
       double purchaseTotal = 0;
       double sellingTotal = 0;
       double total;
       Scanner sc = new Scanner(System.in);
       System.out.println("Enter number of shares: ");
       sharesOfStock = sc.nextInt();
       System.out.println("Enter purchase price : ");
       pricePerShare = sc.nextDouble();
       System.out.println("Enter purchase commission : ");
       commissionRate = sc.nextDouble();
       commissionRate = commissionRate / 100;
       System.out.println("Enter sales price");
       salePrice = sc.nextDouble();
       System.out.println("Enter sale commission");
       saleCommision = sc.nextDouble();
       saleCommision = saleCommision / 100;
       // finding the amount paid only to the stock
       double totolStock = (sharesOfStock * pricePerShare);
       // finding the commission
       double commission = totolStock * commissionRate;
       // finding purchase total
       purchaseTotal = totolStock + commission;
       //finding selling price
       sellingTotal = sharesOfStock * salePrice;
       //finding selling price after commission
       sellingTotal = sellingTotal - (sellingTotal * saleCommision);
       //finding profits and losses
       total = sellingTotal - purchaseTotal;
       // if total is negative than it is loss
       System.out.println("Shares = "+sharesOfStock);
       System.out.println("Purchase price = "+pricePerShare);
       System.out.println("Purchase commission = "+(commission*100));
       System.out.println("Sale price= "+salePrice);
       System.out.println("Sale commission= "+(saleCommision*100));
      
      
       if (total < 0) {
          
           total=total*-1;
           System.out.println("Net loss $" + total);
       } else {
           System.out.println("Net profit $" + total);
       }
   }
}
