推荐答案

// this line is a method call, not a definition.
main(String[] args);
// it should be just
main(args);

你的意思是某些像

Do you mean somehting like

import java.util.Scanner;
import java.util.*;
import java.time.*;
import java.time.format.*;

public class Game
{
  public static void main(String[] args)
  {
    Scanner scan = new Scanner(System.in);
    String name, birthday;
    long age;
    String answer;

    do
    {
      System.out.println("To get started, enter your name.");

      name = scan.nextLine();

      System.out.println("Enter your Date Of Birth. (YYYY MM DD)");

      birthday = scan.nextLine();

      //CALCULATING AGE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
      DateTimeFormatter formatter = DateTimeFormatter.ofPattern("uuuu MM dd", Locale.ENGLISH);
      LocalDate dateofbirth = LocalDate.parse(birthday, formatter);
      LocalDate now = LocalDate.now();
      age = java.time.temporal.ChronoUnit.YEARS.between( dateofbirth , now );
      // DONE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

      System.out.println("Are you " + age);
      answer = scan.nextLine();
    } while ( ! answer.toUpperCase().equals("YES") );

    System.out.println("Goodbye " + name );
  }
}
