Hey there, one more question, if you have time. Let's say I am the user and
I want to enter a name "Alex" and then I sold 5 of Product 2 and I also sold
4 of Product 3. Is there a way I can enter in Alex the number and the
product amount then hit salesman entry done and then put his name in again
Alex but then a different product and amount and when it displays still only
have his name listed once with everything added together?

Thank you so much for your reply. Everything is running great!! I
appreciate your help very much!!

Sure.. Just added a Number_of input field or better yet use a JSpinner for user to select the number_of. I can pass you code if you have a hard time with that.

I would not use a switch on product for subtotals. In your sample, I would have an array of 2 dimensions call it 'ProductCostArray'. The first Dim is your product code (index++), since this is what the numbers are now. The second dim would be [0]cost_product and [1]sales_amt you multiply. This way you can just loop thru and calculate in three lines of code.

Good place to look for examples is at "The Java Developers Almanac 1.4":
http://javaalmanac.com Just search for the object to see examples.

Take a peek at the JTextComponent. You can do some really neat things with this, it in respect to formating.

Take a look at JGoodies Forms and L&Feel Libs at https://jgoodies.dev.java.net for a layout manager. I find it to have more power than GridBagLayout but with a tenth of the headaches.

Hope this make sense. Not sure where you are going with this but you should start thinking about persistence.

Thanks in Advance...
