Java Hibernate validation return invalid fields

I am working with Validation annotations from Java Hibernate in my projects. I want to validate the data that I receive and return an array of invalid fields. Is that possible?

Let's say I have a Java class named Car:

public class Car {

    @NotNull
    private String manufacturer;

    @NotNull
    @Size(min = 2, max = 14)
    @CheckCase(CaseMode.UPPER)
    private String licensePlate;

    @Min(2)
    private int seatCount;

    public Car ( String manufacturer, String licencePlate, int seatCount ) {
        this.manufacturer = manufacturer;
        this.licensePlate = licencePlate;
        this.seatCount = seatCount;
    }

    //getters and setters ...
}

Let's say I create a new Car: 

Car c = new Car("AUDI", NULL, 1);

This should not be possible because the license plate should be filled in and the number of seats should be greater than or equal to 2. So I want to return an array of two elements saying that license plate and number of seats are invalid (with extra message if possible).

As ElmerCat points out, your constructor should be defined as:

public Car (
  @NotNull String manufacturer,
  @NotNull @Size(min = 2, max = 14) @CheckCase(CaseMode.UPPER) String licensePlate,
  @Min(2) int seatCount) {
    this.manufacturer = manufacturer;
    this.licensePlate = licensePlate;
    this.seatCount = seatCount;
}
