大寫伺服器的執行個體：

package com.core.net;import java.io.BufferedReader;import java.io.BufferedWriter;import java.io.InputStreamReader;import java.io.OutputStreamWriter;import java.io.PrintWriter;import java.net.ServerSocket;import java.net.Socket;class TransClient{public static void main(String[] args) throws Exception {Socket socket = new Socket("localhost", 10005);//鍵盤輸入BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));//socket輸入資料流BufferedReader bufin = new BufferedReader(new InputStreamReader(socket.getInputStream()));//socket輸出資料流//BufferedWriter bufout = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));PrintWriter bufout = new PrintWriter(socket.getOutputStream(),true);String line = null;while((line = reader.readLine())!=null){if("over".equals(line))break;bufout.println(line);//bufout.write(line);//bufout.newLine();//***要注意 "\r\n"//bufout.flush();String str = bufin.readLine();System.out.println("server:"+str);}reader.close();socket.close();}}class TransServer{public static void main(String[] args) throws Exception {ServerSocket ss = new ServerSocket(10005);     Socket s = ss.accept();     String ip = s.getInetAddress().getHostAddress();     System.out.println(ip+"......connection"); BufferedReader reader = new BufferedReader(new InputStreamReader(s.getInputStream()));// BufferedWriter out = new BufferedWriter(new OutputStreamWriter(s.getOutputStream())); PrintWriter out = new PrintWriter(s.getOutputStream(),true);  String line = null; while((line = reader.readLine())!=null){  System.out.println(line); out.println(line.toUpperCase());// out.write(line.toUpperCase());// out.newLine();// out.flush(); } s.close(); ss.close();}}public class TransDemo {public static void main(String[] args) {}}

檔案上傳執行個體：

package com.core.net;import java.io.BufferedReader;import java.io.FileReader;import java.io.FileWriter;import java.io.InputStreamReader;import java.io.PrintWriter;import java.net.ServerSocket;import java.net.Socket;/* *將檔案上傳  * */class TextClient{public static void main(String[] args) throws Exception {Socket s = new Socket("localhost", 10006);//注意這裡的檔案路徑非常重要，找了好久的錯誤BufferedReader reader = new BufferedReader(new FileReader("src/com/core/net/IPDemo.java"));PrintWriter bufout = new PrintWriter(s.getOutputStream(),true);String line = null;while((line = reader.readLine())!=null){bufout.println(line);}s.shutdownOutput();//關閉資料流，輸出結束標誌BufferedReader bufin = new BufferedReader(new InputStreamReader(s.getInputStream()));String str = bufin.readLine();System.out.println(str);reader.close();s.close();}}class TextServer{public static void main(String[] args) throws Exception {ServerSocket ss = new ServerSocket(10006);Socket s = ss.accept();String ip = s.getInetAddress().getHostAddress();System.out.println(ip+".....connection");BufferedReader bufin = new BufferedReader(new InputStreamReader(s.getInputStream()));PrintWriter out = new PrintWriter(new FileWriter("server.txt"),true);String line = null;while((line =bufin.readLine())!=null){out.println(line);}PrintWriter pw = new PrintWriter(s.getOutputStream(),true);pw.println("上傳成功");out.close();s.close();ss.close();}}public class UploadText {public static void main(String[] args) {}}
