01.socket定义
在这里插入图片描述

02.TCP编程

import java.io.IOException;
import java.io.OutputStream;
import java.net.InetAddress;
import java.net.Socket;public class clientSocket {public static void main(String[] args) throws IOException {Socket socket=   new Socket(InetAddress.getLocalHost(),9999);System.out.println("客户端的socket"+socket.getClass());OutputStream outputStream= socket.getOutputStream();outputStream.write("hello ".getBytes());outputStream.close();socket.close();}
}

      ServerSocket server=new ServerSocket(9999);Socket socket= server.accept();InputStream inputStream=socket.getInputStream();byte[] readruf=new byte[1024];int readlen=0;while((readlen=inputStream.read(readruf))!=-1){System.out.println(new String(readruf,0,readlen));}inputStream.close();server.close();、    socket.close();
