I tried your applet for the calculation and it worked in java sun but how do I make the calculations work
How would i get this one to work with an applet?
import java.io.*;

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

    BufferedReader stdin = new BufferedReader
      (new InputStreamReader(System.in));
     // declares three integers
    double num1, num2, sum, dollars; // declares a number that can

have decimals

    System.out.print ("What is the amount of your Withdrawl? $");
    System.out.flush();

    // read a line, and then converts it to an integer
   num1=Double.parseDouble(stdin.readLine());

    System.out.print ("What is the amount of your Deposit? $");
    System.out.flush();
    num2 = Double.parseDouble(stdin.readLine());

    sum = num1 - num2; // Adds the two numbers;
    dollars = 1000.09 - sum;
    System.out.println("Your Balance is : $" + dollars);
  } // method main
}
