Java网络编程实例---------------------------------基本HTTP客户端及服务端多线程

HTTP 1.0客户端

package com.bq;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.InetAddress;
import java.net.Socket;

public class Client {
    public Client() throws Exception {
        Socket server = new Socket(InetAddress.getLocalHost(), 8000);
        BufferedReader in = new BufferedReader(new InputStreamReader(
                server.getInputStream()));
        PrintWriter out = new PrintWriter(server.getOutputStream());
        BufferedReader wt = new BufferedReader(new InputStreamReader(System.in));
        while (true) {
            String str = wt.readLine();
            out.println(str);
            out.flush();
            if (str.equals("end")) {
                break;
            }
            System.out.println(in.readLine());
        }
        server.close();
    }

    public static void main(String[] args) throws Exception {
        new Client();
    }
}

HTTP Server

package com.bq;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;

public class Server {

    public Server() throws IOException {

        BufferedReader in = new BufferedReader(new InputStreamReader(
                client.getInputStream()));
        PrintWriter out = new PrintWriter(client.getOutputStream());
        while (true) {
            String str = in.readLine();
            System.out.println(str);
            out.println("Receive from Client...." + str.toUpperCase());
            out.flush();
