hi, can someone explain, how creditcard validation is happening in java? Since we may have some application and there we will be entering creditcard details, but creditcards may be from some HSBC or ICICI bank,, So, from our application, how it is validating, is it a valid creditcard?

The Apache Commons library has a class that validates the CC number. If you want to validate whether the card itself is valid, then you need to sign up with a merchant processing service and use its API. That will cost you money for each check. Google for "creditcard merchant processing" to find such companies.
