Jakarta Bean Validation

Jakarta Bean Validation is a technology that helps ensure data in an application meets specific rules or standards. For example, it can check if a user’s email is valid, if a password is strong enough, or if a required field isn’t empty. It works by attaching these rules to data fields in a program, and then automatically verifying they’re correct before processing. This makes applications more reliable and reduces errors, while also providing clear feedback when data doesn’t meet expectations. Essentially, it helps maintain data quality and consistency in software systems.
