getAllByName()
.
It should read
public static InetAddress InetAddress.getByName(String hostname)
public static InetAddress[] InetAddress.getAllByName(String hostname)
public static InetAddress InetAddress.getLocalHost()
p. 65: In Example 4-7 "helios" should be
"spacecadet". In other words
import java.net.*;
class macfaq {
public static void main (String args[]) {
try {
InetAddress macfaq = InetAddress.getByName("www.macfaq.com ");
InetAddress spacecadet = InetAddress.getByName("spacecadet.cnet.com");
if (macfaq.equals(spacecadet)) {
System.out.println
("www.macfaq.com is the same as spacecadet.cnet.com");
}
else {
System.out.println
("www.macfaq.com is not the same as spacecadet.cnet.com");
}
}
catch (UnknownHostException e) {
System.out.println("Host lookup failed.");
}
}
}
Furthermore, since the book was written, www.macfaq.com has moved off of
spacecadet.cnet.com onto a new host. Thus if you run this you
won't get the results shown in the book.
p. 68, first paragraph: Change
"polymorphic newInetAddressFactory()
methods."
to "... overloaded newInetAddressFactory()
methods."
p. 68, Example 4-8: Change
// Use a byte array like {199, 1, 32, 90} to build
// an InetAddressObject
to
// Use a byte array like {(byte) 199, (byte) 1, (byte) 32, (byte) 90}
// to build an InetAddressObject
p. 74: In the last paragraph "11:53 PM" should be "10:53 PM"
p. 75: The last item in the date brackets is the difference between Coordinated Universal Time (CUT, essentially Greenwich Mean Time) and the local time zone. For instance in "[01/Jan/1996:22:53:58 -0500]" the "-0500" says the logal time zone is five hours earlier than CUT.
p. 76, Ex. 4-11 around line 26: Change
java.net.InetAddress.getByName(thisIP);
to InetAddress.getByName(thisIP);
The java.net
prefix is not explicitly necessary,
though it is not incorrect.
p. 77: Change "Finally the hostname, a space, and everything else on the line (theRest
) is printed on System.out
." to "Finally the hostname and everything else on the line (theRest
) is printed on System.out
."
