I can't figure out, why casting to a subclass causes an unchecked cast
warning, when a wildcard type is involved, but seems to work in any other
case:
Example:

What  does the operator:
^=
do?
I have it used in code I am working with as:

I have just discovered that joda does not parse datetimes that contain
timezones. Hence I am forced to use the date parsing routines in
java.util. But they do not seem to handle bad dates. For example,
2008-13-01 parses as if it was 2008-01-01. I can even give it the 30th

Is it OK to call Cipher.getInstance() before each decrypt/encrypt
operation, or is it better to reuse an instance (or, in a
multi-threaded environment, have a pool of them)?
This came up because I'm working on something that uses nCipher's JCE

I was hoping someone could help me with a simple regular expression
dilemma.  I'm using Java 1.5.  I have this code:
       String regex = accountid;                   // value is
9998698989898

Is there in java class or method to get Physical Address of computer
for Windows, Linux, Unix based system?
And if you can, please write example.

Hi every one
Good Day
How can I change Date format in DateChooser from default format
7/24/09 (m/d/yy) to 2009-07-24 (yyyy-mm-dd)

I'm running NetBeans 6.7 on an elderly ADM 64-bit box running Ubuntu.
I'm having trouble reloading the plug-in catalog. I am getting the error
Unable to connect to the NetBeans because of
java.net.UnknownHostException: updates.netbeans.org

I have a string that seems to be truncated at around 900 chars (due to
how the output is used it is hard to tell exactly how many [println a
length would break half a dozen programs])... if this a real limit or
dis something weird just happen...

I stayed "connected" with this thread of the Jumble algorithm and its
complexity. I was curious mainly on how well (or bad) my implementation
would
perform compared to that of Matthews and how a similar algorithm to

Folks
Are there any advantages in speed in passing a List or an Iterator as a method parameter, or as a method return value?
Any runtime reasons why one should be preferred over the other?
Thanks - Adam

Hi, I have a C/C++ background and I'm learning a bit
of java now and I was curious if, for the purpose of
returning a value from a funcion, it was possible to
do the following:
