网络编程【六】Tcp服务端与客户端互相通信

客户端代码：

package com.zzl.tcp;

import java.net.*;
import java.io.*;
public class TcpClient {

	public static void main(String[] args)throws Exception {
		Socket s = new Socket("192.168.0.124",10003);
		InputStream in = s.getInputStream();
		OutputStream out = s.getOutputStream();
		
		out.write("服务端，你好，我是客户端，收到请回答".getBytes());
		
		byte[] buf = new byte[1024];
		int len = in.read(buf);
		System.out.println(new String(buf,0,len));
	}

}

服务端代码：

import java.net.*;
import java.io.*;
class TcpServer {

	public static void main(String[] args)throws Exception {
		ServerSocket ss = new ServerSocket(10003);
		Socket s = ss.accept();
		InputStream in = s.getInputStream();
		OutputStream out = s.getOutputStream();
		
		byte[] buf = new byte[1024];
		int len = in.read(buf);
		System.out.println(new String(buf,0,len));
		
		out.write("哈哈，客户端你也好，我收到了".getBytes());
	}

}

首先运行服务端，然后运行客户端。

服务端打印如下：

客户端打印如下：
