錯誤上的PriorityBlockingQueue

Question

我試圖使用PriorityBlockingQueue類的一個實例：

public static PriorityBlockingQueue<Message> messagesQueue = new PriorityBlockingQueue<Message>(); 

public static void EnqueueMessage(Message message) 
{ 
    messagesQueue.add(message); 
} 

和我的編譯器不斷拋出一個奇怪的錯誤：

Description Resource Path Location Type

這裏是給messageManager ：

public class MessageManager extends Thread { 
    @Override 
    public void run() { 
     // TODO Auto-generated method stub 
     while (true) 
     if (!messagesQueue.isEmpty()) 
      { 
       //pull message from queue 
       Message message = messagesQueue.remove(); 

       //dispatch messages according to their type 
       switch(message.mflag) 
       { 
       case EM_BOOTSTRAP: 
        CJournal.Journal(MessageManager.class, "Messaging system working properly."); 
       default: 
        CJournal.Journal(MessageManager.class, "Default Dispatch Message Trashed"); 
       } 
      } 
     } 
    } 


    public static PriorityBlockingQueue<Message> messagesQueue = new PriorityBlockingQueue<Message>(); 

    public static void EnqueueMessage(Message message) 
    { 
     messagesQueue.add(message); 
    } 

     //called upon when object is no longer needed 

     public void Destroy() 
     { 
      //called Destroy 
     } 

     //called every turn. checks messagemanager for message 

     public void ParseMessage() 
     { 

     } 


     public static void Launch() {} 


     //called on object creation 

     public static void Init() {} 



     public static void Render() 
     { 

     } 


     public static void Collision() 
     { 

     } 

     //when the game requires this particular state to be active 

     public static void OnEnter() 
     { 

     } 

     //When the object no longer needs to be attachd to the scene graph 

     public static void OnExit() 
     { 
     } 

     //for exammple, hitting the pause button 

     public static void OnSuspend() 
     { 
     } 


    public static void Train() 
    { 
     //incoming messages are analyzed and sent 
     //to the trainer to record the behavior for the AI 
    } 

}

Answer 1

總而言之，編譯器提供了編譯錯誤，其中包括語法錯誤的列表，以及它們的詳細說明。請仔細查看每個錯誤並正確糾正實施情況。

已發現的一些問題。

IBaseNPC接口

1. 某些字段沒有指定的類型。考慮更新的字段，例如，如下：所分配的值的

   int direct_damage = 0; 
   int energy_damage = 0; 
   

2. 領域缺乏。考慮引入的場的初始化，例如，如下：

   boolean is_stealthing = false; 
   

MessageManager類

1. 大括號不均衡。考慮正確糾正大括號。
