import java.util.Set;

public class ValidatorExample {
    public static void main(String[] args) {
        ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
        Validator validator = factory.getValidator();
        
        // Create objects to validate
        User user = new User();
        user.setCpf("123.456.789-09"); // Insert your CPF for testing

        clientP.setDocument("123.456.789-09"); // Insert your CPF for testing
        
        // Validate objects
        Set<ConstraintViolation<User>> userViolations = validator.validate(user);
        Set<ConstraintViolation<Company>> companyViolations = validator.validate(company);
        Set<ConstraintViolation<Client>> clientCOViolations = validator.validate(clientCO);
        Set<ConstraintViolation<Client>> clientPViolations = validator.validate(clientP);
        
        // Handle violations as needed
        if (!userViolations.isEmpty()) {
            userViolations.forEach(violation -> System.out.println(violation.getMessage()));
        }

            companyViolations.forEach(violation -> System.out.println(violation.getMessage()));
        }

        if (!clientCOViolations.isEmpty()) {
