Question

Look at Stock and StockDriver. Get these programs to run. We will be keeping track of both our cost and the fair market value of our shares of stock.

import java.text.*;

public class Stock {

   // this line is used to output money but this is NOT considered a field
   NumberFormat money = NumberFormat.getCurrencyInstance();

   // create five fields - a String called stockName, a integer called custID
   // a integer called numShares, a double named costPaid,and a double called currentValue
   // Do not forget the access modifier
   public String stockName;
   public int custID;
   public int numShares;
   public double costPaid;
   public double currentValue;
       // create an empty and full constructor
  
   public Stock()
   {
   }
  
   public Stock(String s, int c, int n, double co, double cv)
   {
       stockName = s;
       custID = c;
       numShares = n;
       costPaid = co;
       currentValue = cv;
   }
   public String toString() {
       return custID + " owns " + numShares + " shares of " + stockName
               + " worth " + money.format(currentValue) + " per share. You paid "+
               money.format(costPaid) + " per share.";
   }

   // write a calcCost method that takes no parameters and returns a double
   // Have it return the total cost you paid for the stock
  
   // write a method named calcCurrentValue that takes no parameters and returns a double
   // that is the current value of the stock.

   // write your getters and setters. You should at least once try to create
   // these by hand so you understand them
   // (even though Eclipse will write these for you)
   // (DO NOT create one for money - it really is not a field)

}

Sample output:

Customer id: 1234

Name of stock: IBM

Number of shares: 200

Price paid per share: 60.00

Current value per share: 65.00

1234 owns 200 shares of IBM worth $65.00 per share. You paid $60.00 per share.

The total cost of the stock is $12,000.00 and the current value is $13,000.00

More stocks to calculate? (true or false)

true

Customer id: 3434

Name of stock: GOOG

Number of shares: 120

Price paid per share: 45.00

Current value per share: 120.00

3434 owns 120 shares of GOOG worth $120.00 per share. You paid $45.00 per share.

The total cost of the stock is $5,400.00 and the current value is $14,400.00

More stocks to calculate? (true or false)

false

The above is the complete code to the problem. It consists of two files Stock.java and StockDriver.java which should be kept int the same directory.

Output of the above code:

note: In my case it is showing currency as rupees because I am from India. However it will show the currency according to the region\country where you live.
