How could I write this in java
I have to use a parameter in a statement. I am trying but its giving error. I am trying to write it like ....
fw.write("Object dir/my.dat\n");I substitute my.dat with a variable dat & write like
fw.write("Object dir/+"dat"+\n");dat is a String variable.

thanks,welcome
How could I remove this error.
Unreported exception java.io.IOException; must be caught or declared to be thrown fw.write("#the number of patterns to be recognized\n");
Its for every fw.write statement.read the Sun (Oracle?) [tutorial on exceptions,|http://java.sun.com/docs/books/tutorial/essential/exceptions/index.html] and then either throw the exception or wrap in a try / catch block (the tutorial will explain how).

How could u write this application?
write an application to read an unknown number of integer pairs representing binary numbers from a file redirected input from the command line. do not use sentinel value or prompt.
1. Echo print in colums 1 and 2 the numbers that were read.
2. Convert each number to decimal for columns 3 and 4.
3. Count the number of 1's in the numbers for columns 5 and 6.
4. Find the larger of the decimal versions of the first and second number of each integer pair, and print that number in column 7.
5. Keep separate cumulative sum of the decimal versions of the first and second number of each integer pair, and print that number below the appropriate column after all numbers have been read.
Sample output:
10 11 101 1111 111 10000 101011 0
thanks for your interest> hey young fella, its not a HW or something!! everyone
talks alot here like they know everthing(which they
aint gotta clue), i decided to put an easy
application to c how many people are going to be able
to write this application??
That's a little tough to believe. It's far more likely that you need some help on figuring out how to go about writing such an application. There's nothing wrong with that; just know that most folks who volunteer to help here aren't particularly interested in "proving their skills" by way of programming "challenges". They typically get far more satisfaction by helping others learn Java.
i guess u r one those fellas who dont have a clue about java!!! b/c if u
were not, this would take ur 5-6 mins of time..
So, do you have a specific question regarding those requirements? If you do, please ask. If, on the off chance you've got some special insight regarding an implementation, post your idea and get some feedback from the community.
Also, please make the extra effort to write out words such as "see", "you", "are", "your", and "because". The extra keystrokes won't cost much in the way of time, and the enhanced clarity will be appreciated by those communicating on a forum with international readership. Also, it will give the appearance that you take your question seriously, which will in turn make your question look more interesting to answer.
Thanks!

I am trying to create a shared object that will host a chat
room environment. I will have many of these rooms and I know what I
want to do, just not how to write it in actionscript or if it is
even possible. the underlined portion is what i just don't know how
to code (
(room + roomNumber + _so) ) as it should throught usage
equate to something like
room1_so,
room2_so,
room3_so, and so on. any help would be greatly appreciated.
thanks in advance.
function doJoin(roomNumber) {
(room + roomNumber + _so) = SharedObject.getRemote(
(room + roomNumber + _so) ,_root.clientroom_nc.uri,true);
if(
(room + roomNumber + _so) ).data.seat1 = occupied) {
do this;
}its actually connecting to flash media server remote shared
object as opposed to the local shared object. The code in question
was actually taken nearly word for word from the macromedia sample
file so I know that that portion is correct.
If I replace the shared object name from
tl["room"+roomNumber+"_so"].connect(_root.clientroom_nc);
and change it to
room1_so.connect(_root.clientroom_nc);
everything works fine and the connection is succesful,
however since I hope to have many many rooms that is just not a
feasible way to write it. I have racked my brain trying to think of
an alternative way of writing it but have come up with nothing. I
am well versed in Basic, PHP, and some C, but this damn
actionscript stuff is throwing me for a loop since it is incredibly
different in a lot of ways. -
List v = new Vector() how can i write this ?
List v = new Vector() how can i write this ?
vector does not 'extends' List rather it 'implements' only ......so how can write this way ? ( polymorphism applies only for 'extends' ).my question in a simple way is :
List some_list extends Vector
No, List is an interface; Vector is a concrete class. Read the javadocs.
Vector implements List
>
AND
List some_list implements Vector
are these two same in behaviour
our apart from theoretical differences ?thanks
Interfaces don't have any implementation; they're pure method signatures. When a concrete class implements an interface, it makes a promise that says "I will provide implementations for exactly these methods. Any client can call a method from the interface and I will do something 'sensible' if I'm written correctly."
From the point of view of static and dynamic types, there's no difference between interfaces and classes.
C++ has interfaces, too - they're classes with all pure virtual methods. If you understand how C++ works, the concept shouldn't be hard.
ArrayList is preferred precisely because it isn't synchronized by default. (You can always make it so using java.util.Collections if you wish later on.) If you don't need synchronization, why pay the performance penalty? -

Hi, I upgraded my iphone 4 (4.3.3) to iso 5 beta 6, but now it shows "No Service" at top left, and unable to complete your activation. Also tells that "this device is not registered as part of the iphone developer programme." How could I fix this problem? Please help me...,
I had a similar occurrence with my just activated iPhone 4.
I had been using the phone for three days when an odd occurrence with voice mail caused me to call tech support. After some discussion they decided to push the activation to my phone (even though I had been using it for three days). When I went to power it back up again I repeatedly got the "no service" notification. I got tech support on a land line and we tried hard reboots and so on. No joy. They told me to take it in to the point of sale and either the SIM card or the phone needed (or both) needed replacing.
I tried one last hard reboot after dinner and the phone came up with service, but I took it in to the point of sale in the morning and they swapped the SIM card out and I went to a Genius Bar appointment to get the phone checked out. It is supposedly OK, but I am still having some problems when syncing it so I will have to visit the Genius Bar again tomorrow about that. At least I have not experienced the "no service" problem in the roughly 24 hours since the SIM card was replaced. (Fingers crossed) -

Hii 2 all
How could I change this statement for parameters list,, so the client_name can contain spaces ??
add_parameter(p_id,'p_client_name',TEXT_PARAMETER, '''' || :cntrl.client_name || '''');
cause it couldn't print and give syntax error when the :cntrl.client_name contains any spaces !!!!
please help
thanks:)First I must apologize, I asked you to test something that was not needed... for a moment I thought we were talking about web.show_document, that's why I asked you to test with double-quotes..
Regarding your problem, Manu is right, there is not need to wrap around the parameter in quotes..
add_parameter(p_id,'p_client_name',TEXT_PARAMETER, :cntrl.client_name);I have to ask you the same question that Manu asked you before, where are you using this parameter?
In your Report you must be using in a piece of PL/SQL code, we need you to post that code...

Check the iPhoto preferences:
From the main menu bar: iPhoto > Preferences > General:
"Connecting camera opens" : Set this option to "iPhoto".
If that does not help, disconnect your iPhone and reset your iPhone.
To reset iPhone, press and hold the Sleep/Wake button and the Home button at the same time for at least 10 seconds, until the Apple logo appears. -
My QuickTime player us not playing .avi files and says I need a codec I can't play no .avi files on QuickTime. How could I fix this because I want to play these files with QuickTime.
Hmm . . . comes with a Utility MPEG2 Component ML app with no explanation of what it's for?
The utility app is an "assistant PKG installer." It allows Lion and Mountain Lion users to install the older QT MPEG-2 Playback Component installer PKG file which is not allowed to run on its own under Lion or Mountain Lion since these operating systems already have a QT X only MPEG-2 component embedded in the QT embedded structure. Without this utility you would have to either copy the component from an older system to your Lion or Mountain Lion system, use Pacifist for installation, or manually open the PKG contents and transfer the component to the appropriate component folder.
As to your "discussion" regarding the playback of AVI file types, there are really only two strategies here:
1) You can add component support so that QT can play the files natively or
2) You can convert the file contents to compression formats that are natively compatible with the unmodified QT component configuration.
Each user should decide for his or her own self which approach best suits their needs for a particular source file. In most cases, conforming the system's codec component configuration to play the source file directly results in higher video quality since no transcoding takes place but this strategy will not work if a codec which is required is not available for the user's operating system. On the other hand, converter utilities tend to support more built-in codecs and are easier to use since the user does not have to concern him or herself with the nature of the particular source compression formats but at the risk of some potential loss in visual quality. As to what converter to use, once again this is a matter of personal choice. In the case of commercial converters like iSkysoft, the codecs are built in while MPEG Streamclip accesses the host operating system's QT codec component configuration. I personally prefer the free HandBrake app for AVI, MKV, TS, MTS, and M2TS conversions since it has an exceptionally full-featured X.264 GUI with some user options that 97% of users are likely to never use. -

Unbenannt 11.vi 43 KBWell, at least you tried and got some of it right.
I think this should do what you want, but my C is rusty. Is the increment performed before or after the loop executes? If it's after, then I believe the loop should iterate 11 times, not 10.
In any case, you should note that for a literal translation, you would need to add a sequence structure to guarantee that Y was written to only after the inner loop finished because of the way data-flow works.. Also, note that controls and indicators in LabVIEW are not equivalent to variables. They can be used as such, but they usually should not be.
Another point about this is that you probably want to use the correct data type - the orange terminals are floating point indicators (of double precision, in this case) and you want integers.
To learn more about LabVIEW, I suggest you try looking at some of these tutorials.
Try to take over the world!

I don't know the owner I found an iPhone4 how could I use this???
i don't know the owner how could I use this???
If you found a phone you should take it to the police. You don't have the right to hang onto it. If it's not claimed after a period then you may be able to retain it. But in any case if it is 'Activation Locked' only the original owner can unlock it. There is no way round this, and without being able to contact him (and if you could you should return it) the phone is permanently unusable if locked in this way.
