我在DatagramPacket的问题，我也说不清楚，大家帮我看看
程序如下：
import java.io.*;
import java.net.*;
import java.util.*;
public class UDPClient {
public UDPClient() {
}
public static void main(String[] args) throws IOException {
try{
args = new String[4];
args[0] = "192.168.5.103";
DatagramPacket packet = null;
DatagramSocket socket = new DatagramSocket();
Byte buf[] = new Byte[265];
InetAddress address = InetAddress.getByName(args[0]);
System.out.print(buf.length);
packet = new DatagramPacket(buf, buf.length, address, 4445);
socket.send(packet);
packet = new DatagramPacket(buf, buf.length);
socket.receive(packet);
String re = new String(packet.getData());
System.out.print(re);
} catch (UnknownHostException e){
System.out.print(e);
}
}
} 抱错：
Lession/lesson1/UDPClient.java [35:1] cannot resolve symbol
symbol : constructor DatagramPacket (java.lang.Byte[],int,java.net.InetAddress,int)
location: class java.net.DatagramPacket
packet = new DatagramPacket(buf, buf.length, address, 4445);
^
Lession/lesson1/UDPClient.java [39:1] cannot resolve symbol
symbol : constructor DatagramPacket (java.lang.Byte[],int)
location: class java.net.DatagramPacket
packet = new DatagramPacket(buf, buf.length);
^
