ＵＤＰ编程例子．采用ＪＡＶＡ 网络编程．

public class mulUdpRecv
{
	public static void main(String[] args) throws Exception
	{
		System.out.println("\n");
		while (true)
		{
			DatagramSocket ds=new DatagramSocket(5000);
		    byte[] buf=new byte[1024];
		    DatagramPacket dp=new DatagramPacket(buf,1024);
		    ds.receive(dp);
			System.out.println(new String(dp.getData(),0,dp.getLength()));
			ds.close();
		}
	}
}
