Java开发实现的Socket双向通信功能示例

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();

}
