1.问题：在学习Java的Socket编程，写了一些代码练习，但是又不知道是否规范，是否有优化的空间？

2.代码：

package com.nekolr.socket;

import com.google.common.util.concurrent.ThreadFactoryBuilder;

import java.io.*;

import java.net.ServerSocket;

import java.net.Socket;

import java.util.concurrent.*;

/**

public class TcpSocket {

static class TcpServer implements Runnable {

private int port = 8888;

@Override

public void run() {

try (

//创建服务端Socket，监听端口

ServerSocket serverSocket = new ServerSocket(port)

) {

//打开监听，等待客户端的连接(在连接到来之前一直阻塞)

Socket socket = serverSocket.accept();

try (

//获取输入流(获取客户端的消息)

InputStream is = socket.getInputStream();

InputStreamReader isr = new InputStreamReader(is, "utf-8");

BufferedReader reader = new BufferedReader(isr)

) {

String line;

while ((line = reader.readLine()) != null) {

System.out.println("客户端" + socket.getInetAddress().getHostAddress() + "发送消息：" + line);

}

} catch (IOException e) {

e.printStackTrace();

}

} catch (IOException e) {

e.printStackTrace();

}

}

}

static class TcpClient implements Runnable {

private String host = "localhost";

private int port = 8888;

@Override

public void run() {

try (

//创建客户端Socket，指定主机名和端口号

Socket socket = new Socket(host, port)

) {

try (

//获取输出流(向服务端发送消息)

OutputStream os = socket.getOutputStream();

OutputStreamWriter osw = new OutputStreamWriter(os, "utf-8");

BufferedWriter writer = new BufferedWriter(osw)

) {

int i = 0;

while (true) {

i++;

writer.write("hello" + i);

writer.newLine();

}

} catch (IOException e) {

e.printStackTrace();

}

} catch (IOException e) {

e.printStackTrace();

}

}

}

public static void main(String[] args) {

TcpServer tcpServer = new TcpServer();

TcpClient tcpClient = new TcpClient();

ThreadFactory factory = new ThreadFactoryBuilder().setNameFormat("thread-pool").build();

ExecutorService executor = new ThreadPoolExecutor(2, 2,

0L, TimeUnit.MILLISECONDS,

new LinkedBlockingQueue<>(1024), factory, new ThreadPoolExecutor.AbortPolicy());

executor.execute(tcpServer);

executor.execute(tcpClient);

}

}
