TCP协议学习简单案例

1.在TCP协议中，不用关闭流对象，关闭Socket和ServerSocket对象就可以了2.传输中都是以字节输入输出流实现的

Client.java

import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java.net.Socket;/** * 客户端 * Created by Aongi on 2017/5/4. * Version 1.0 */public class Client {    //main方法    public static void main(String[] args) throws IOException {        Socket socket = new Socket("127.0.0.1",8888);        //发送数据给服务器端        OutputStream os = socket.getOutputStream();        os.write("服务器你收到了吗？".getBytes());        //接受服务器端返回的数据        InputStream is = socket.getInputStream();        byte[] bytes = new byte[1024];        int i =  is.read(bytes);        System.out.println(new String(bytes,0,i));        //关闭socket对象        socket.close();    }}

Server.java

import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java.net.ServerSocket;import java.net.Socket;/** * Created by Aongi on 2017/5/4. * Version 1.0 */public class Server {    //main方法    public static void main(String[] args) throws IOException {        ServerSocket serverSocket = new ServerSocket(8888);        Socket socket = serverSocket.accept();        //接收客户端发送的消息        InputStream is = socket.getInputStream();        byte[] bytes = new byte[1024];        int i = is.read(bytes);        System.out.println(new String(bytes,0,i));        //返回消息给客户端        OutputStream os = socket.getOutputStream();        os.write("我收到了！".getBytes());        //关闭socket对象，关闭serverSocket对象        socket.close();        serverSocket.close();    }}
