import java.util.Scanner;

public class License {

    public String firstUpperCase(String word){
        if(word == null || word.isEmpty()) return ""; //или return word;
        return word.substring(0, 1).toUpperCase() + word.substring(1);
    }

    public void Check(Scanner in, License license){

        System.out.print("Enter your age: ");
        int age = in.nextInt();

        if(age < 18) {
            System.out.println("Please, wait " + (18 - age) + " years");
        }

        if(age >= 19){

            System.out.print("Enter your first name: ");
            String firstName = in.next();

            System.out.print("Enter your last name: ");
            String lastName = in.next();


            firstName = license.firstUpperCase(firstName);
            lastName = license.firstUpperCase(lastName);



            System.out.println("Your first name: " + firstName + "\nYour last name: " + lastName);
        }
    }
    
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        License license = new License();
        license.Check(in, license);
