Simple POS System in Java

[amsroxy1125]

I am wondering if anyone has a simple POS system created using Java that I could look at. I am working on creating my own, but I need some help on where to start. If anyone has a sample POS system that I could look at that would be great!

a POS system is?

I know the internet term for POS, but I don't think it applies here :p Although if it does, this is the perfect forum for finding them.

POS - Point of Sale, I need a simple POS display code that shows the item number, the item, and the total of the item. Like when you go shopping and the associate scans the barcode and it populates on the screen. Is that more clear??

Thanks!

yep, but really it depends how simple you want it. I have some old assignments you can use as a basis. You would more than likely still need to include code to scan the barcodes into the system and implement classes/methods for this. and fix a number of odd things.

Really??? That would be great if I could take a look. I am just needing a GUI that displays a box so the associate can input an item code and hit enter. Then the screen should display the item code, the name, and the amount.

Yea probably not going to be any help then... It's all console based, and is low level programming.

But pseudocode for this is pretty easy, just create your driver class with array and constants. perhaps have a product database, which can be simply a text file with values if your not proficient with relational databases. Allow use of user login: when program starts up, you can have boolean variable 'loggedIn' set to false, display login menu, read usernames/passwords from encrypted file and test against the input.
set to loggedIn, which displays main menu, and reads database file to array in background. Product scanning would definitely the code you want at this point. Some samples you may be able to find on the web, but may just lead to more confusion...
store each product in a mini array for each product on the docket, at POS this array would print out for docket. something like that...

allow the use of admins to add new products to database, security level can be included in userName/password file as:

name(string):password(string):securityNumber(int)
