}기능을 루핑 및 자바

나는 현재 서버에서 브로드 캐스트 메시지를 수신하기위한 클라이언트 프로그램을 구축하고 바이트를 수신하는 단계를 포함한다. 일을 분명하게하고 싶다면, startRunning() 메소드가 아무도 호출하지 않고 루핑을 계속한다는 것이 맞습니까? 또한 들어오는 데이터는 바이트 형태로되어 있습니다.이 메시지를 읽거나 저장하기 위해 .read (message) 메서드를 사용할 수 있습니까?

startRunning() 메서드는 아무도 호출하지 않고 루핑 자체를 유지한다는 것이 맞습니까?

코드 실행을 시작하려면 startRunning() 메서드를 적어도 한 번 호출해야합니다. 그 후에 while 블록은 예외가 발생하지 않는 한 무한 루프를 반복합니다.

들어오는 데이터는 바이트 형식입니다. 읽을 수있는 메시지 (message)를 사용하여 메시지 []에 데이터를 저장할 수 있습니까?

예, 가능합니다. 내가 팁을 추가 할 수 있습니다 경우 사양

이 link를 참조하십시오

private boolean Continue = true; 

public void setContinue(boolean b) 
{ 
    Continue = b; 
} 


public void startRunning() throws IOException 
{ 
    DataInputStream in; 
    try 
    { 
     while (Continue) 
     { 
      System.out.println("receive"); 
      InputStream inFromServer = myClient.getInputStream(); 
      in = new DataInputStream(inFromServer); 
      in.read(message); 
      System.out.println(Arrays.toString(message)); 
     } 
    } 
    catch (EOFException eofexception) 
    { 
     System.out.println("error"); 
    } 
    catch(Exception ex) 
    { 
     in.close(); 
     throw ex; 
    } 
}

참고하면서 루프의 상태. 이렇게하면 인터럽트에 대한 응답 성이 향상됩니다. 스트림을 무한히 열어서는 안됩니다.

또한 예외가 발생하면 스트림을 닫아야합니다.
