服務(wù)器端的寫法

package com.chinasofti.corejava.ch22;

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

try {

ss=new ServerSocket(5500);

System.out.println("服務(wù)器正常啟動。。。。");

//調(diào)用ServerSocket的accept方法，可以接受客戶端的請求，并返回當(dāng)前的Socket對象

s=ss.accept();//阻塞方法

System.out.println("連接成功"+s.getRemoteSocketAddress());

//獲得基于Socket的輸入流

br=new BufferedReader(new InputStreamReader(s.getInputStream()));

//獲得基于Socket的輸出流

pw=new PrintWriter(new OutputStreamWriter(s.getOutputStream()));

while(true){

String string=br.readLine();

System.out.println("Server讀到："+string);

System.out.println("Server端請輸入：");

String str=scanner.next();

pw.flush();

if(str.equals("exit")){

break;

}

}

客戶端的寫法

package com.chinasofti.corejava.ch22;

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.io.OutputStreamWriter;

import java.io.PrintWriter;

import java.net.InetAddress;

import java.net.Socket;

import java.util.Scanner;

public class Client {

private static PrintWriter pw=null;

private static BufferedReader br=null;

private static Socket s;

static Scanner scanner=new Scanner(System.in);

/**

* @param args

*/

public static void main(String[] args) {

// TODO Auto-generated method stub

try {

s=new Socket(InetAddress.getLocalHost(),5500);

pw=new PrintWriter(new OutputStreamWriter(s.getOutputStream()));

br=new BufferedReader(new InputStreamReader(s.getInputStream()));

while(true){

System.out.println("Client端請輸入：");

String str = scanner.next();

pw.println(str);

pw.flush();

String string=br.readLine();

System.out.println("Client讀到："+string);

if(str.equals("exit")){

s.close();

break;

}

}

}catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

try {

br.close();

pw.close();

} catch (IOException e1) {

// TODO Auto-generated catch block

e1.printStackTrace();

}

}

}
