TCP与UDP编程在java项目中有哪些区别-创新互联

这篇文章给大家介绍TCP与UDP编程在java项目中有哪些区别，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。

TCP

客户端：

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

public class MyClient {

  public static void main(String[] args) throws Exception{
    
    Socket socket = null;
    BufferedReader in = null;
    PrintWriter out = null;
    
    BufferedReader input = null;
    // 请求指定ip和端口号的服务器
    socket = new Socket("127.0.0.1",3333);
    
    while(true){

      in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
      
      out = new PrintWriter(socket.getOutputStream(), true);
      // 接收控制台的输入
      input = new BufferedReader(new InputStreamReader(System.in));
      // out.println("this is client info!");
      String info = input.readLine();
      
      out.println(info);
      
      String str = in.readLine();
      
      System.out.println("客户端显示--》服务器的信息：" + str);
    }
    //in.close();
    //out.close();
  }
