Usage

public class Test {

    /**
     * Example operations using an Estonian personal code.
     */
    public static void main(String[] args) {
        // Generate personal code.
        EstonianPersonalCodeGenerator generator = new EstonianPersonalCodeGenerator();
        String personalCode = generator.generateRandomPersonlCode(); // 37209030023
        // Validate personal code.
        EstonianPersonalCodeValidator validator = new EstonianPersonalCodeValidator();
        boolean isValidFormat = validator.isValidFormat(personalCode); // true
        boolean isValid = validator.isValid(personalCode); // true
        // Extract data from personal code.
        EstonianPersonalCodeParser parser = new EstonianPersonalCodeParser();
        LocalDate dateOfBirth = parser.getDateOfBirth(personalCode); // 03.09.1972
        Gender gender = parser.getGender(personalCode); // MALE
        int birthOrderNumber = parser.getBirthOrderNumber(personalCode); // 2
    }
