자바 BufferedReader, Writer 순서

게시물 수정 , 삭제는 로그인 필요

SampleClient 코드를 보면 OutputStream을 먼저 작성하고 BufferedOutputStream 다음줄에 OutputStreamWriter을 작성하잖아요 근데 SampleServer 코드를 보면 InputStream 다음 InputStreamReader 다음 BufferedReader을 작성하는데 왜 클라이언트 쪽과 서버 쪽 순서가 다른 건가요?? 설명 부탁드립니다.. ㅜㅜ

그리고 저 코드들을 한줄로 표현해 봤는데 맞게 작성했는지 한 번만 봐주세요 ㅠㅠ 각각 코드 아래에 첨부하겠습니다

SampleClient 코드는 29번째줄부터 SampleServer 코드는 24번째줄부터 입니다!

- SampleClient 코드

public class SampleClient implements Runnable {

private InetAddress destination; 

private int port; 

public SampleClient(InetAddress dest, int port) {

this.destination = dest;

this.port = port;

}

public void run() {

try {

Socket link = new Socket(destination, port);

System.out.println("Client : Connected!");

OutputStream toServer = link.getOutputStream();

toServer = new BufferedOutputStream(toServer);

Writer toServerWriter = new OutputStreamWriter(toServer);

Scanner scanner = new Scanner(System.in);

while(true) {

System.out.print("CLIENT >> ");

String msg = scanner.nextLine();

toServerWriter.write(msg);

toServerWriter.write('\n');

toServerWriter.flush();

if(msg.equals("종료")) {

break;

}

}

toServer.close();

link.close(); 

} catch (IOException e) {

System.out.println(e);

}

}

}

- SampleServer 코드

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.net.ServerSocket;

System.out.println("Server : Accepted!");

InputStream fromClinet = linkToClient.getInputStream();

Reader fromClinetReader = new InputStreamReader(fromClinet);

BufferedReader bR = new BufferedReader(fromClinetReader);

while(true) {

String msg = bR.readLine();

if(msg.equals("종료")) {

break;

} else {

System.out.println("SERVER RECEIVED\n" + msg);

}

}

bR.close();

linkToClient.close();

link.close();

} catch (IOException e) {

System.out.println(e);

}

}

}
