Credit Card Validator Demo

Checks for valid credit card numbers using Luhn algorithm. This is an example of how identical code can be used to improve server side security and user experience on the client.

The algorithm is implemented in CreditCardValidator.java. It validates a list of hard-coded credit card numbers, or any number passed as command line arguments. For example, try CreditCardValidator.html?myNumber=4417-1234-5678-9113

Here and with the Java 5 Features Demo you see that the values of URL query parameters are passed to the declared onLoad-method.
