import java.io.*;
class Elevator{
  boolean running = true;
  void shutDown(){
    running = false;
  }
class FrontDesk{
  private final int EVENING = 8;
  Elevator NorthElevator, SouthElevator;
  
  FrontDesk() {
    NorthElevator = new Elevator();
    SouthElevator = new Elevator();
  }
  void maintenance(int time){
    if(time==EVENING)
      NorthElevator.shutDown();
    }
  
    
  void displayStatus(){
    System.out.print("North Elevator is ");
    if(!(NorthElevator.running))
      System.out.print("not");
    System.out.println("running.");
    System.out.print("South Elevator is ");
    if(!(SouthElevator.running))
      System.out.print("not");
    System.out.println("running.");
  }
}
}
public class Hotel{
  public static void main(String args[]){
    FrontDesk lobby;
    lobby = new FrontDesk();
    System.out.print("It's 7:00 tTime to check the ");
    lobby.maintenance(7);
    lobby.displayStatus();
    
    System.out.println();
    System.out.println("It's 8:00 Time to cheack the ");
    lobby.maintenance( 8 );
    lobby.displayStatus();
  }
}

这个程序编译出错
显示
D:\rabbit\java\exercise\Hotel.java:35: cannot resolve symbol
  symbol : class FrontDesk
location: class Hotel
   FrontDesk lobby;
^
D:\rabbit\java\exercise\Hotel.java:36: cannot resolve symbol
symbol : class FrontDesk
location: class Hotel
    lobby = new FrontDesk();

难道这里定义方法有错?
