        try {
            DatagramSocket client = new DatagramSocket();
            String sendStr = "Hello! I'm Client";
            byte[] sendBuf;
            sendBuf = sendStr.getBytes();
            InetAddress addr = InetAddress.getByName("127.0.0.1");
            int port = 8088;
            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("服务端说:" + recvStr);
            client.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

import java.net.DatagramSocket;
import java.net.InetAddress;
public class Server {

                    recvBuf.length);
            server.receive(recvPacket);
            String recvStr = new String(recvPacket.getData(), 0,
                    recvPacket.getLength());
            System.out.println("客户端说:" + recvStr);
            int port = recvPacket.getPort();
            InetAddress addr = recvPacket.getAddress();
            String sendStr = "Hello ! I'm Server";
            byte[] sendBuf;
