Hi....I am writing this program for my course. I have been mucking around
with doubles and floats...etc. Though I have tried to set the variables to
double, I get compile errors. I have changed Integer.parseInt (initString)
to Double.parseDouble(initString) but this compiles an error and too mention
that double A_Invest; also compiles an error.

What I am asking is, Can someone show me how to change the Integer.parseInt
(initString) so I can accept decimal input from the command line. Here is my
source code:-




import java.io.*;

 public class Investment {

   public static void main (String[] args)
       throws IOException
   {

     BufferedReader stdin   =   new BufferedReader
        (new InputStreamReader (System.in));


     String initString;
     int A_Invest;
     int N_Years;
     int Interest_Rate;
     int Value;
     int j;

     System.out.print ("Enter the amount to invest: ");
     initString      =   stdin.readLine();
     A_Invest   =   Integer.parseInt (initString);

     System.out.print (" ");

     System.out.print ("Enter the Interest Rate:");
     initString    =   stdin.readLine();
     Interest_Rate   =   Integer.parseInt (initString);

     System.out.print (" ");

     System.out.print ("Enter the number of years: ");
     initString      =   stdin.readLine();
     N_Years   =   Integer.parseInt (initString);

     System.out.print (" ");

Value = A_Invest * (1 + Interest_Rate) * N_Years;

j = 1;
for (int i = 0; i < N_Years; i++) {
      System.out.print ("The value of your " + j++);
      System.out.print (" Year return will be: " + Value);
      System.out.println (" ");
    }
  }
}
