title: Some java Datagram Socket questions
body: <p>I have recently nose dived into socket programming using java, and I have a few general sort of questions.</p>
  
  <p>There is a bind() method, as well as a connect() and disconnect(). There is no unbind(). Is this because upon disconnecting the socket is unbound? Does garbage collection take care of this once the program exits? Or is this not even a valid question?</p>
  
  <p>Also, upon creating a DatagramSocket, how is it different if I only provide the port and the address? I am creating a program to collect data off a network, as the data floats around and log it. Should I just use the local address? Could not using the address when I create the socket cause me to not be able to collect packets?</p>
  
  <p>I am just trying to get a stronger understanding on the inner-workings of these things. </p>
