when posting code here, you'll want to use correct code tags so that your code will retain its formatting and thus will be readable -- after all, your goal is to get as many people to read your post and understand your code as possible, right?

To do this, highlight your pasted code (please be sure that it is already formatted when you paste it into the forum; the code tags don't magically format unformatted code) and then press the code button, and your code will have tags.

Another way to do this is to manually place the tags into your code by placing the tag [cod&#101;] above your pasted code and the tag [/cod&#101;] below your pasted code like so:

[code]
  // your code goes here
  // notice how the top and bottom tags are different
[/code]

Also, you've appeared to have corrected the error in your import statement What is your current question?

Put each class into its own file.

Interesting how this exact same program has made the rounds, several posts months apart. I mean it is word for word the same program. Look here:

Java Programming - I need help with this inventory program

It even has the same question and requires the same answer. Strange.
