ArrayList listOfLists = new ArrayList();
                    for (int ix = 0; ix < numBehaviors; ix++) {
                    listOfLists.add(new LinkedList());
STUFF FOIR ADDING
                         ((java.util.List) listOfLists.get(0)).add("hi");
                         ((java.util.List) listOfLists.get(1)).add("this");
                         ((java.util.List) listOfLists.get(2)).add("is");
                         ((java.util.List) listOfLists.get(2)).add("a");
                         ((java.util.List) listOfLists.get(2)).add("test");

prints "[[hi], [this], [is, a, test]]" for me. the problem has to be in the code you haven't posted.

I have sync'd my new ipad with my itunes library on my computer and it says the sync is complete and everything dandy. However, when I launch itunes on the ipad and select the music tab, all I see is the new stuff that is avaiable for sale and download.

Where is my actual library of music on my Ipad? Its right here in my face on my computer (hundred's of songs) but nowhere to be found on the ipad despite syncing the device. *** ? SUPER-frustrating !!

If your ipad music bought via iTunes that you can transfer the music back to computer.It supports all apple device included ipad.You need exchange a new hard-disk drive,and sync music files again.
Besides what mentioned above, you also refer this article about how to transer or sync iPad contents to computer.
Hope that it can do your a favor.

Where can I download fcp rescue for 4.5 or need help with crashing

Hi guys,
I'm still running 4.5 and haven't had a lot of problems with it in the past 2 years. I can't get the program to open today however. It keeps getting stuck on "profiling for rt extreme". I've trashed all the preferences, rebooted, and searched this forum for answers, but am still having problems.
In one post I found a link for fcp rescue, but it looks like they've taken off old versions of the program. I can only download for fcp 5.
Does anyone know where I could still download this program from FCP 4.5? or Can anyone suggest trying something other than trashing preferences or reinstalling?

FCP Rescue for Four and 4.5 are the same program.
As to your issue, I'd make sure you don't have any errant USB/FW devices plugged in. And I believe you get the Profiling for RT Extreme when there are no preferences, so it would seem that you've done that part right...

Hard drive crash... need help with i Tunes....

Hello all,
Here is the problem. A couple of weeks ago my girlfriend's hard drive crashed. I was able to pull her hard drive out and slave it to mine, in order to save her docs/pics/I-tunes. I got everything off and burned it to a couple of DVDs.
My question is how do I get those music files (the ones I recovered) back on to her new computer?
Thanks,
Jason
Windows XP
PS. Her i-Pod does have all of her music files... If that matters...

There's a program called PodUtil (http://www.kennettnet.co.uk/software/podutil.php)-the trial works, you don't have to buy it. And you can get all of the songs/videos from your girlfriend's iPod and move it to a designated folder, once you do that, simply add folder to iTunes. Hope I helped...post questions if you have any.

I found a download of Cascade Menu with files from 2001. I also found a discussion thread as of 2006 indicating problems with the script in Firefox as of that time ([http://www.webdeveloper.com/forum/archive/index.php/t-94019.html Menubar Script problem in FireFox [Archive] - WebDeveloper.com]). The web and web browsers have changed a lot during the past decade, so you might find it more efficient to get a new menu script than to fix this old one. (It might not even work in IE9 any more...)

I Recently got a used iPod touch, version 3.1.3. I do not know how to reset everything. First I have tried to reset all settings, but it asks for restriction code. Also, my iTunes does not recognize it. Please help!

I just purchased this movie on Thursday, May 15, so just a few days ago. I have never had any trouble whatsoever since I have been in Vietnam. I have downloaded several movies and even music and they have all synced to my respected Apple products except for this purchase.
Sorry, I don't quite understand what you mean by studios and different versions. Could you please explain?
I checked my purchased list in my purchase history under my account and there are no hidden items.

Need help with duplicate print jobs over network that I can't cancel

I have the Photosmart Premium All-in-One on my home network. My kids who each have laptop running Windows 7 and are connected via wireless to the printer via a DLINK DIR-655.
They hit the print button too many times and it keeps printing over and over again.
Is there a way to get the printer to stop printing these duplicates. I tried turning off/on but they just keep printing.
We're wasting paper/ink and I need help with a solution.
Please let me know. Thanks.
Angelo

There should be a button with a red 'X' on it on the front of the printer. This is the print cancel button.
Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.

I need help with re installing my apple account for itunes.

Had problems with my itune account, so I uninstalled and now need help with re-installing the program with the songs I have already purchased.

Your iTunes account is something at the iTunes Store online. It is not possible to uninstall it. Do you mean the iTunes application? Even if you delete the application and restore it, it should not have deleted your iTunes library (essentially the contents of the iTunes folder in Music) on your computer unless you did a separate steep and specifically deleted that too. You need to tell us what it was you deleted.

I have the latest version of Apple TV. I buy videos off iTunes. I subscribe to iCloud. Yet so many times when I try and access the stuff that I paid for via the device that I paid through the cloud that I paid for - I can't

I only get the message that I can't access iTunes and to try again later. Every time I try later I get the sam message. What am I doing wrong? Why buy all this stuff if it doesn't work? Apple has an incredible reputation, but you stuff that doesn't work, and how do you get someone to sort it for you as per any company who sold you a series of stuff that didn't work. Who do I call? What do I do? I just want the stuff that I paid for to work. Is this unreasonable? Is there a consumer regulatory group that anyone can recommend that could approach about stuff that you buy that doesn't work?

you dont need computer. go to settings > icloud and turn off what you dont want like photostream/calendars/contacts. for itunes 11.1 you need to go to itunes.com and download it then install it.

I need help with circular linked list

Hi,
I need help with my code. when I run it I only get the 3 showing and this is what Im supposed to ouput
-> 9 -> 3 -> 7
empty false
9
empty false
3
-> 7
empty false
Can someone take a look at it and tell me what I'm doing wrong. I could nto figure it out.
Thanks.This is my code

I'm not going thru all the code to just "fix it for you". But I do see one glaringly obvious mistake:
for(int i = 0; i < -999; i++)That says:
1) Initialize i to 0
2) while i is less than -999, do something
Since it is initially 0, it will never enter that loop body.

Does anyone know of a simple to do list app that syncs between an iPhone and a Mac?

Does anyone know of a simple to do list app that syncs between an iPhone and a Mac?

Not sure exactly what you are going for...
You're aware you need to use iTunes to sync apps between your iPhone and Mac unless you are running V10.7.2 and have iCloud setup.
BTW... apps that are optimized for an iPhone will not run on the Mac OS X and vice versai, two different operating systems.
It really helps to tell us which Mac OS X you have installed when you post for help. Thanks!
