该楼层疑似违规已被系统折叠 隐藏此楼查看此楼

java代码如下，UDP 客户端 utf-8编码

package xj.ne;

/**

* UDP客户端 UTF-8编码

*/

import java.io.*;

import java.net.*;

public class UDPClient{

public static void main(String[] args)throws IOException{

DatagramSocket client = new DatagramSocket();

System.out.println("请输入内容");

BufferedReader wt = new BufferedReader(new InputStreamReader(System.in));

String sendStr = wt.readLine();

byte[] sendBuf;

sendBuf = sendStr.getBytes("UTF-8");

InetAddress addr = InetAddress.getByName("127.0.0.1");

int port = 27015;

DatagramPacket sendPacket

= new DatagramPacket(sendBuf ,sendBuf.length , addr , port);

client.send(sendPacket);

byte[] recvBuf = new byte[100];

DatagramPacket recvPacket

= new DatagramPacket(recvBuf , recvBuf.length);

client.receive(recvPacket);

String recvStr = new String(recvPacket.getData() , 0 ,recvPacket.getLength());

System.out.println("收到:" + recvStr);

client.close();

}

}
