　　 i use Java udp socket write a program today.
　　classes used:
　　DatagramScocket(int port);
　　DatagramPacket(byte[] buf, int length, InetAddress address,int port); //for send
　　DatagramPacket(byte[] buf, int length); //for receive
　　implements:
　　first, construct a DatagramSocket object with a specified port.
　　then construct a DatagramPacket with a buffer, length, InetAddress and port to send you message,
　　the message is stored in the buffer which is a byte array.
　　also you can construct a DatagramPacket with a buffer and length to recieve message from the port blinded with you socket.
　　note:
　　if you send message to a server that not recieve you message , the message is lost. this future is differnet to tcp connetion.
　　so to make udp program , you must deal with package lost!!!
　　udp为不可靠传送，必须处理包丢失的问题
