TCP通信之客户端开发 客户端发送信息
import java.io.*;
import java.net.*;public class TCPClient {public static void main(String[] args) {final String serverAddress 127.0.0.1; // 服务器地址final int serverPort 8080; // 服务器端口try {// 连接到服务器Socket socket new Socket(serverAddress, serverPort);System.out.println(Connected to server.);// 发送消息到服务器sendMessage(socket, Hello, Server!);// 接收服务器的响应String response receiveMessage(socket);System.out.println(Response from server: response);// 关闭连接socket.close();} catch (IOException e) {e.printStackTrace();}}private static void sendMessage(Socket socket, String message) throws IOException {PrintWriter out new PrintWriter(socket.getOutputStream(), true);out.println(message);}private static String receiveMessage(Socket socket) throws IOException {BufferedReader in new BufferedReader(new InputStreamReader(socket.getInputStream()));return in.readLine();}
