服务器未正确读取发送的UDP数据包

Question

I'm sending two packets from a client to server. The issue I'm having is the data being read on the server makes both strings the same length with regards to the longest string sent. For example:

if string 1 was : 1234
and string 2 was: abcdefghi

the server would read

1234efghi
abcdefghi

It should just display

1234
abcdefghi

My code is:

byte[] toSendUser = new byte[1024];
byte[] toSendPass = new byte[1024];

String name = "1234";
String password = "abcdefghi"; 

    toSendUser = name.getBytes();
        toSendPass = password.getBytes();
        DatagramPacket packSend = new DatagramPacket (toSendUser, toSendUser.length, ipConn, 9876); 
        connection.send(packSend);

        DatagramPacket packSendtwo = new DatagramPacket (toSendPass, toSendPass.length, ipConn, 9876); 
        connection.send(packSendtwo);

Could it be a server issue or is my code wrong in my client?

DatagramPackets in Java keep shrinking to the size of the smallest one received so far. You have to either create a new one per receive(), or at least reset the length every time before the next receive().
