本文实例讲述了Java开发实现的Socket双向通信功能。分享给大家供大家参考，具体如下：

服务端

import java.io.BufferedReader;import java.io.BufferedWriter;import java.io.IOException;import java.io.InputStreamReader;import java.io.OutputStreamWriter;import java.net.ServerSocket;import java.net.Socket;import java.util.Scanner;public class Server_1 { public static void main(String[] args) { InputStreamReader isr; BufferedReader br; OutputStreamWriter osw; BufferedWriter bw; String str; Scanner in = new Scanner(System.in); try { ServerSocket server = new ServerSocket(4444);// 在本机的4444端口开放Server Socket socket = server.accept();// 只要产生连接，socket便可以代表所连接的那个物体，同时这个server.accept()只有产生了连接才会进行下一步操作。 System.out.println(socket.getInetAddress());// 输出连接者的IP。 System.out.println("建立了一个连接！"); while (true) { isr = new InputStreamReader(socket.getInputStream()); br = new BufferedReader(isr); System.out.println(socket.getInetAddress() + ":" + br.readLine()); osw = new OutputStreamWriter(socket.getOutputStream()); bw = new BufferedWriter(osw); System.out.print("回复:"); str = in.nextLine(); bw.write(str + "\n"); bw.flush(); } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } }}

客服端

import java.io.BufferedReader;import java.io.BufferedWriter;import java.io.IOException;import java.io.InputStreamReader;import java.io.OutputStreamWriter;import java.net.ServerSocket;import java.net.Socket;import java.util.Scanner;public class Client_1 { public static void main(String[] args) { InputStreamReader isr; BufferedReader br; OutputStreamWriter osw; BufferedWriter bw; String str; Scanner in = new Scanner(System.in); try { Socket socket = new Socket("localhost", 4444);// System.out.println(socket.getInetAddress());// 输出连接者的IP。 System.out.println("成功连接服务器"); while (true) { osw = new OutputStreamWriter(socket.getOutputStream()); bw = new BufferedWriter(osw); System.out.print("回复:"); str = in.nextLine(); bw.write(str + "\n"); bw.flush(); isr = new InputStreamReader(socket.getInputStream()); br = new BufferedReader(isr); System.out.println(socket.getInetAddress() + ":" + br.readLine()); } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } }}
