【服务端】

import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java.net.ServerSocket;import java.net.Socket;//服务端public class MyServer {        public static void main(String[] args) {        ServerSocket serverSocket = null;        Socket socket = null;        try {            //创建监听1515端口的ServerSocket对象            serverSocket = new ServerSocket(1515);            //堵塞等待客户端的请求，当收到请求就返回Socket对象            socket = serverSocket.accept();            //从Socket对象获取输入流和输出流            InputStream in = socket.getInputStream();            OutputStream out = socket.getOutputStream();            //通过输入流读取客户端发送的数据            byte[] bt = new byte[1024];            int len = in.read(bt);            String data = new String(bt, 0, len);            System.out.println(data);            //通过输出流向客户端返回数据            out.write("服务器已收到！！！".getBytes());        } catch (IOException e) {            e.printStackTrace();        } finally {            //关闭资源            if (socket != null) {                try {                    socket.close();                } catch (IOException e) {                    e.printStackTrace();                }            }            if (serverSocket != null) {                try {                    serverSocket.close();                } catch (IOException e) {                    e.printStackTrace();                }            }        }    }}

 

【客户端】

import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java.net.Socket;import java.net.UnknownHostException;//客户端public class MyClient {    public static void main(String[] args) {        Socket socket = null;        try {            //创建连接服务端的Socket对象            socket = new Socket("127.0.0.1", 1515);            //从Socket对象获取输入流和输出流            InputStream in = socket.getInputStream();            OutputStream out = socket.getOutputStream();            //通过输出流向服务端发送数据            out.write("来自客户端！！！".getBytes());            //通过输入流读取服务端返回的数据            byte[] bt = new byte[1024];            int len = in.read(bt);            String data = new String(bt, 0, len);            System.out.println(data);        } catch (UnknownHostException e) {            e.printStackTrace();        } catch (IOException e) {            e.printStackTrace();        } finally {            //关闭资源            if (socket != null) {                try {                    socket.close();                } catch (IOException e) {                    e.printStackTrace();                }            }        }    }}
