上传txt文本 通过socket向服务端发送数据 然后用serversocket 接收socket 通过流读取数据保存 服务端在发送确认信息并在客户端输出

客户端

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
import java.net.UnknownHostException;


public class txtClient {

	 * @param args
	 * @throws IOException 
	 * @throws UnknownHostException

		Socket s = new Socket("10.64.130.51", 10002);
		
		BufferedReader br =
			new BufferedReader(new FileReader("F:\\fd.txt"));
		
		PrintWriter pw = new PrintWriter(s.getOutputStream(), true);
