Hi!

I'm new to Java programming. I have a program due for class next week
and I'm having some difficulties.

I've done a little programming before, but not very good at it! LOL

One of my biggest problems (and there are many!) is that I'm not
familiar with Java. I downloaded the latest version of Java from SUN.
I'm just not real sure how to use it. The teacher gave an example but
mine doesn't seem to be working.

First, I typed to program (based on a sample from my book) into notepad
and saved it as LoanKEG.java into the bin directory on my java program.
When I go to the command line and bring up the directory and type the
commands that the teacher gave (C:\Documents and Settings\Administrator>cd..
C:\Documents and Settings>cd..
C:\>f:
F:\>path=c:\Program Files\Java\jdk1.5.0\bin
F:\>javac NewFeatures.java (the name of the program is actually LoanKEG)
F:\>java NewFeatures
...

If I'm in that directory and bring up the command line, then the command
line brings me to: C:\Program Files\Java\jdk1.5.0_01\bin.

When I type javac LoanKEG.java it comes back and says "Exception in
thread "main" java.lang.NoclassDefFoundError: LoanKEG

I'm not sure what to do. Here is the code that I wrote for the program:
Any help is appreciated!!!

             // Compute the monthly interest rate, as a fraction

         double rate = (ANNUAL_RATE/100.0)/12.0;

             // principalRemaining will contain the amount of the loan that
             // is not yet paid off.

         double principalRemaining = LOAN_AMOUNT;

             // totalInterest will contain the total amount of interest
paid over
             // the life of the loan.

         double totalInterest = 0.0;

             // Make a counter for the number of months
         int months = 0;

             // Loop as long as the remaining principal is greater than 0

          while (principalRemaining > 0.0)
          {
              months++;

  }

         NumberFormat moneyFormat = NumberFormat.getCurrencyInstance();

         System.out.println("It will take " + months +
             " months to pay off a loan of " +
moneyFormat.format(LOAN_AMOUNT));

         System.out.println(
             "at an annual interest rate of " + ANNUAL_RATE + "%.");

         System.out.println("You will pay a total of " +
             moneyFormat.format(totalInterest) + " in interest.");
     }
