JSR 380

JSR 380, also known as Bean Validation 2.0, is a Java specification that provides a standardized way to define and enforce validation rules on object properties, such as ensuring a user's email is valid or a number falls within a specific range. It helps developers specify constraints directly on data models, making applications more reliable by catching invalid data early. This framework simplifies validation logic, promotes consistency across applications, and integrates smoothly with Java-based systems, enhancing data integrity and reducing errors without extensive custom coding.
