Pattern matching

I am writing a class to do pattern matching for checking whether the user entered pan number is valid or not.This pan number is a field of a custom object.Please help me how should I fetch this object and perform pattern matching.

Thanks in advance!!!

Hi Revati,

You don't need to create an Apex class to validate a pattern, you can use just a validation rule and a REGEX expression.
This link [1] should be helpful for you.

Also, check this link [2] in order to learn more about Validation Rules, you'll find some common examples in it.
