Question

Use this method:

In a program that calculates the total profit or loss from the saleof multiple stocks. The program should ask the user for the numberof stock sales, and the necessary data for each stock sale. Itshould accumulate the profit or loss for each stock sale and thendisplay the total.

import java.util.Scanner;       //Needed for Scanner class

public class StockProfit
{
   public static void main(String[] args)
   {
       int sale;                
       double NS, PP, PC, SP,SC;
       double profit;
      
       // Create a Scanner objectfor kb input.
       Scanner kb = newScanner(System.in);
      
  
       // Get answers from theuser
       System.out.print("Enter thenumber of Shares: ");
       NS = kb.nextDouble();
      
       System.out.print("Enter thePurchase Price per share: ");
       PP = kb.nextDouble();
      
       System.out.print("Enter thePurchase Commission paid: ");
       PC = kb.nextDouble();
      
       System.out.print("Enter theSale Price per share: ");
       SP = kb.nextDouble();
      
       System.out.print("Enter theSale Commission paid: ");
       SC = kb.nextDouble();
      
       // Calculation
// You could have used test = caculate_Profit_or_Loss( NS, SP, SC,PP, PC) ;   i.e define only one method
// In that method you could have used you formula and returned theresult to test variable

       profit = ((NS * SP) - SC) -((NS * PP) + PC);
       //----------------------------------------------
       // Determine whether thecalculation yields a
       // positive value or negativevalue.
       //----------------------------------------------
       if (profit >0)      // if(test > 0) yougained a profit
       {
           // CallProfit method
           doubleans1 = prof(NS, SP, SC, PP, PC);
           //Display
       }
       else if (profit <0)   // else you incurred a loss
       {
           // CallLoss method
           doubleans2 = loss(NS, SP, SC, PP, PC);
       }
   }
  
   // Profit method
   public static double prof(double ns, double sp,double sc, double pp, double pc)
   {
       double result;
      
       result = ((ns * sp) - sc) -((ns * pp) + pc);
       System.out.println("Theamount of the profit: "
                         + result);
       return result;
   }
   public static double loss(double ns, double sp,double sc, double pp, double pc)
   {
       double result;
      
       result = ((ns * sp) - sc) -((ns * pp) + pc);
       System.out.println("Theamount of the loss: "
                         + result);
       return result;
   }
}
