Programing 实验物联2班 201208080228赵智慧实验题目：利用套接字编程，编写出TCP和UDP的客户机、服务器程序进行交互实验代码：TCP服务器：package TCP;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.net.ServerSocket;import java.net.Socket;public class TCPServer {public static void main(String[] args) throws IOException{ServerSocket server=new ServerSocket(7999);System.out.println(server ok);Socket socket=server.accept();BufferedReader bf=new BufferedReader(new InputStreamReader(socket.getInputStream()));String str=bf.readLine();while(str!=null){System.out.println(str);str=bf.readLine();}}}TCP客户机：package TCP;import java.io.BufferedReader;import java.io.DataOutputStream;import java.io.IOException;import java.io.InputStreamReader;import java.io.OutputStream;import java.io.PrintWriter;import java.net.Socket;import java.net.UnknownHostException;public class TCPClient {public static void main(String[] args) throws UnknownHostException, IOException{String sentence;InputStreamReader isr = new InputStreamReader(System.in);BufferedReader inFromUser = new BufferedReader(isr);Socket clientSocket = new Socket(127.0.0.1,7999);sentence = inFromUser.readLine(); OutputStream os = clientSocket.getOutputStream();PrintWriter oos=new PrintWriter(os);os.write(sentence.getBytes());clientSocket.close();}}UDP服务器：package UDP;import java.net.DatagramPacket;import java.net.DatagramSocket;import java.net.InetAddress;import java.net.SocketException;public class UDPServer {public static void main(String[] args) throws Exception{DatagramSocket serverSocket = new DatagramSocket(9876); //所有发送和接收的数据都将通过该套接字 //因为UDP无连接，所以无需创建一个新的套接字监听新的请求byte[] receive1 = new byte[1024];byte[] receive2 = new byte[1024];byte[] send1 = new byte[1024];byte[] send2 = new byte[1024];byte[] send3 = new byte[1024];while(true){DatagramPacket receivePacket = new DatagramPacket(receive1, receive1.length);serverSocket.receive(receivePacket);String str = new String(receivePacket.getData()); //从分组中提取出数据，并存入str中InetAddress ip = receiv
