Try jNetPcap. The site is full of examples and tutorials.

There are a few things you can do. If your end goal is to simply monitor the traffic, use an existing application like Ethereal or Wireshark.

Otherwise, if you want to write your own application, have a look the the Jpcap and/or JNetPcap libraries. They allow you to bind to network interfaces and sniff / analyse all the packets that pass through those interfaces.
