UNCONFIRMED  errors and comments from readers: 


{139}  start of 6th paragraph;
"The third possibility, notification, is new."

This is not true. The "notify" and "notifyall"
method calls have been around for ages.  I know they go
back as far as 1.1.8 (as I just checked the API docs
for that) and I suspect they may go back earlier.


[328]  Example 10-1. Look for local ports;
The ServerSocket object created by the line:

ServerSocket server = new ServerSocket(port);

is never closed. The above line should be followed with something like the following
lines of code:

try
{
    server.close();
}
catch (IOException ex)
{
    System.out.println("Error closing socket on port " + port + ".");
}

This extra try/catch is required to distinguish close errors from bind errors that
are picked up by the existing catch block.



[343]  catch (IOException ex) near end of page;
Code example reads:

      } catch(IOException ex) {
         e.PrintStackTrace();
      }

There is no "e" in that Exception...


{368}at the beginning of page;
I think the method public abstract Socket createSocket(InetAddress host, int port,
InetAddress interface, int localPort) shouldn't throw UnknownHostException.

Although the next method public abstract Socket createSocket(Socket proxy, String
host, int port, boolean autoClose) should throw that UnknownHostException.

So I think the two methods should be printed like this:-

public abstract Socket createSocket(InetAddress host, int port, InetAddress
interface, int localPort) throws IOException

public abstract Socket createSocket(Socket proxy, String host, int port, boolean
autoClose) throws IOException, UnknownHostException


{444} in paragraph 3;
It's in the hardcopy on page 444 in paragraph 3.
The title of the paragraph is:-
public InetAddress getRemoteSocketAddress( )
I think the right should be:-
public SocketAddress getRemoteSocketAddress( )
The method getRemoteSocketAddress() is in class SocketAddress not in InetAddress.
