TCP协议实现数据传输的简单案例

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(); } }
