java barcode reader

Question

anyone have any idea about how to create java program that can read barcode

Answer 1

The main focus would be to understand how bar code readers provide the information for the host PC. Therefore, you should try to learn how Java Programs can read from ports, typically USB port.

Answer 2

You have to understand how barcode readers work, then you need to sort all the information you have gathered and create neat UML diagrams so that you could organize everything you'll need.

But I think this will need more than Java to work, it needs some computer engineering skills as well.

Answer 3

ZXing provides Java source code that reads most any common format (UPC, EAN, QR codes, etc.). It provides source to a complete Android and J2ME app, and source for a basic Java-based app.

Answer 4

Look at the open source Java libraries to generate barcodes such as Barbecue and Barcode4J

http://barcode4j.sourceforge.net supports most formats like Code 39, UPC-A, UPC-E, EAN-13 etc
