While loops

First of all, I can confidently say that me and loops (of ANY kind)
don't go well together. The program I am working on keeps giving me
errors (and when I fix them, there is yet ANOTHER error waiting for
me....maybe Java just isn't my forte). I was to make a program that
would data from a file and then output (into a new file): month count,
starting balance, interest (6% annual), amount deposited, and then
ending balance. It could be that it is 9 am and I am not thinking
straight, but here is my code (don't laugh at me T.T):

/**
 * @(#)Try2.java
 *
 * Try2 application
 *
 * @author
 * @version 1.00 2008/3/6
 */
 import java.util.*;
 import java.io.*;
public class Try2 {

    public static void main(String[] args)throws FileNotFoundException
{
     Scanner in = new Scanner (new FileReader("Annuities.txt"));
     float n = in.nextFloat();
     PrintWriter out = new PrintWriter("Try2.txt");
     int count;
     float sbal;
     float interest = (sbal*.06)/12;
     float deposit = 200.00;
     float ebal = sbal + interest + deposit;
     while(in.hasNext()){
     count = 1;
     System.out.println(count + " " + sbal + " " + interest + " " +
deposit + " " + ebal);
     count++;
     }
     in.close();
     out.close();
    }
}

RESULTS:

--------------------Configuration: Try2 - JDK version 1.6.0_03
<Default> - <Default>--------------------
java.lang.NoClassDefFoundError: Try2
Exception in thread "main"
Process completed.

I KNOW that the input file is there and in the right spot...is it not
finding it?
