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();
}
}
}
