Java network programming explanation

Question

I have refer to following code, i not so understand, can somebody explain it to me? Thanks
try {
e = NetworkInterface.getNetworkInterfaces();
while (e != null && e.hasMoreElements()) {
NetworkInterface net = (NetworkInterface) e.nextElement();
Enumeration enum = net.getInetAddresses();
while (enum.hasMoreElements()) {
InetAddress inet = (InetAddress) enum.nextElement();
new FileServerThread(inet);
catch (SocketException ex) {
}

Answer 1

try {
    // get an Enumeration of network interfaces
    e = NetworkInterface.getNetworkInterfaces();
    // iterate through the Enumeration
    while (e != null && e.hasMoreElements()) {
        // retrieve the next individual NetworkInterface object from
        // the enumeration
        NetworkInterface net = (NetworkInterface) e.nextElement();
        // get the enumeration of InetAddresses from the
        // NetworkInterface
        Enumeration enum = net.getInetAddresses();
        // iterate through the InetAddresses
        while (enum.hasMoreElements()) {
            // get the next InetAddress object from the enumeration
            InetAddress inet = (InetAddress) enum.nextElement();
            // instantiate a new FileServerThread for the given
            // InetAddress
            new FileServerThread(inet);
// catch any thrown Exception objects
catch (SocketException ex) {
} What questions are you having about this pretty basic piece of code?
