title: DatagramPacket to string
body: <p>Trying to convert a received DatagramPacket to string, but I have a small problem. Not sure what's the best way to go about it. </p>
  
  <p>The data I'll be receiving is mostly of unknown length, hence I have some buffer[1024] set on my receiving side. The problem is, suppose I sent string "abc" and the do the following on my receiver side...</p>
  
  <pre><code>buffer = new byte[1024]; 
  packet = new DatagramPacket(buffer, buffer.length);
  socket.receive(packet);
  buffer = packet.getData();
  System.out.println("Received: "+new String(buffer));
  </code></pre>
  
  <p>I get the following output: abc[][][][]][][][]..... all the way to the buffer length.
  I'm guessing all the junk/null at the end should've been ignored, so I must be doing something wrong." I know the buffer.length is the problem because if I change it to 3 (for this example), my out comes out just fine.</p>
  
  <p>Thanks.</p>
