本文通过Java实现了一个简单的TCP客户端和服务端程序，演示了如何利用TCP进行文件的发送与接收。客户端读取本地文件并将其内容发送到指定的服务器地址及端口；服务器接收文件内容并保存为新文件，同时向客户端反馈上传成功的信息。

import java.net.*;
import java.io.*;

class TextClient {		//客户端
	public static void main(String[] args) throws Exception {
		Socket s = new Socket("172.16.41.154", 10003);
		InputStream in = s.getInputStream();
		OutputStream out = s.getOutputStream();

		BufferedReader bufr = new BufferedReader(new FileReader("IPDemo01.java"));
		PrintWriter pw = new PrintWriter(out, true);
		String line = null;
		while((line = bufr.readLine()) != null) {
			pw.println(line);
		}
		s.shutdownOutput();

		BufferedReader skBufr = new BufferedReader(new InputStreamReader(in));
		String str = skBufr.readLine();
		System.out.println(str);

		s.close();
		bufr.close();
	}
}

class TextServer {		//服务端
	public static void main(String[] args) throws Exception {
		ServerSocket ss = new ServerSocket(10003);
		Socket s = ss.accept();

		String ip = s.getInetAddress().getHostAddress();
		System.out.println(ip + "....connecting");
		InputStream in = s.getInputStream();
		OutputStream out = s.getOutputStream();

		BufferedReader skBufr = new BufferedReader(new InputStreamReader(in));
		PrintWriter pw = new PrintWriter(new FileWriter("IPDemo01_copy.txt"), true);
		String line = null;
		while((line = skBufr.readLine()) != null) {
			pw.println(line);
		}
		//PrintWriter skPw = new PrintWriter(s.getOutputStream(),true);
		//skPw.println("上传成功");
		BufferedWriter skBufw = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
		skBufw.write("上传成功");
		skBufw.newLine();
		skBufw.flush();
