I compiled the code and it works

just declare your variables as doubles and
A_Invest   =  Double.parseDouble(initString)

should work



import java.io.*;

 public class Investment {

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

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


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

     System.out.print ("Enter the amount to invest: ");
     initString      =   stdin.readLine();
     A_Invest   =  Double.parseDouble(initString) ;
     System.out.print ("Enter the amount to invest: " +  A_Invest );
     System.out.print (" ");

     System.out.print ("Enter the Interest Rate:");
     initString    =   stdin.readLine();
     Interest_Rate   = Double.parseDouble(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 (" ");
    }
  }
}
