java如何通过tcp发送指令

以下是一个展示java使镇含用tcp通胡岁讯裤旅睁的简单例子，包括服务器和客户端代码：

/**

*TCPServer

*/

import java.io.*

import java.net.*

class TCPServer{

public static void main(String[] args)throws IOException{

ServerSocket listen = new ServerSocket(5050)

Socket server = listen.accept()

InputStream in = server.getInputStream()

OutputStream out = server.getOutputStream()

char c = (char)in.read()

System.out.println("收到:" + c)

out.write('s')

out.close()

in.close()

server.close()

listen.close()

}

}

/**

*TCPClient

*/

import java.io.*

import java.net.*

class TCPClient{

public static void main(String[] args)throws IOException{

Socket client = new Socket("127.0.0.1" , 5050)

InputStream in = client.getInputStream()

OutputStream out = client.getOutputStream()

out.write('c')

char c = (char)in.read()

System.out.println("收到:" + c)

out.close()

in.close()

client.close()

}

}

以派基下是一个展示java使用tcp通讯的简亩闷单例子，包括尘耐谨服务器和客户端代码：\x0d\x0a\x0d\x0a/**\x0d\x0a *TCPServer\x0d\x0a */\x0d\x0aimport java.io.*\x0d\x0aimport java.net.*\x0d\x0aclass TCPServer{\x0d\x0apublic static void main(String[] args)throws IOException{\x0d\x0aServerSocket listen = new ServerSocket(5050)\x0d\x0a\x0d\x0aSocket server = listen.accept()\x0d\x0aInputStream in = server.getInputStream()\x0d\x0aOutputStream out = server.getOutputStream()\x0d\x0achar c = (char)in.read()\x0d\x0aSystem.out.println("收到:" + c)\x0d\x0aout.write('s')\x0d\x0a\x0d\x0aout.close()\x0d\x0ain.close()\x0d\x0aserver.close()\x0d\x0alisten.close()\x0d\x0a}\x0d\x0a}\x0d\x0a\x0d\x0a/**\x0d\x0a *TCPClient\x0d\x0a */\x0d\x0aimport java.io.*\x0d\x0aimport java.net.*\x0d\x0aclass TCPClient{\x0d\x0apublic static void main(String[] args)throws IOException{\x0d\x0aSocket client = new Socket("127.0.0.1" , 5050)\x0d\x0aInputStream in = client.getInputStream()\x0d\x0aOutputStream out = client.getOutputStream()\x0d\x0a\x0d\x0aout.write('c')\x0d\x0achar c = (char)in.read()\x0d\x0aSystem.out.println("收到:" + c)\x0d\x0aout.close()\x0d\x0ain.close()\x0d\x0aclient.close()\x0d\x0a}\x0d\x0a}
