Im new to java and hope somebody can help me with my question
Hi!
Im quite new to java and I just have some simple questions..
can someone please tell what kinds of error are considered as language violation for java? where can I find more info about these errors?
can someone give me a simple example on a kind of error that cannot be caught in both compilation and runtime? I hope someone can help me out. Thanks in advance!!

Im just asking about errors that might go against the language definition but cant be detected.. If it "goes against the language defintion," it will be detected by the compiler. That's half of the compiler's job is to tell you what you've done that violates the language spec.
because it confuses me when they say that such errors might occur so I just want to know what might these errors be.. sorry for that..Who's "they"? What exactly* did "they" say about "such errors"? It sounds to me like you're just confused, and you think there's something mysterious and inexplicable going on but you don't know what and don't even know what you're asking.
I would suggest not worrying about hypothetical problems that you can't even put into words and focussing on learning Java. Along the way, if you encounter real, specific, actual problems, ask about them, and you'll probably get answers about the problems themselves and the language or theory behind them.

Hi hope somebody can help? i have acrobat 6 pro, worked well for last two years but then just stopped working. Have reinstalled but still will not open, ronning windows 7. Help please!! Janice
Hey janicem42177174,
Adobe no longer supports the installation and use of Acrobat 6 as it is a very old version which is not compatible with Windows 7.
I would suggest you to please use the latest version of Acrobat i.e. 11.0.10 which is fully compatible with your OS with its enhanced features and functions.
You might download a free 30-day trial version of Acrobat from here:
Download Adobe Acrobat free trial | Acrobat XI Professional
Let me know how it goes

My iPhone stolen and I download find my iPhone on it also I can sea it online but I can't locate it so please help me .. What should I do . I heard apple support can activate the GBS and send it to my e_mail . So I hope they can help me with that ...
Best wishes ..
<Email Edited by Host>These are user-to-user forums, I've asked the hosts to remove your email address from your post.
Apple and/or iTunes support can't locate it for you, only you can potentially locate it via http://icloud.com on a computer or Find My iPhone / Find My iPad on another device - but that will only work if it's connected to a network and the device hasn't already been wiped and/or Find My iPhone disabled on it.
If it was stolen then you should report it to the police. You should also change your iTunes account password, your email account passwords, and any passwords that you'd stored on websites/emails/notes etc. -
I have 2 problems I hope someone can help me with.
As the title says, I problems I hope someone can help me with as I don't know who else to ask for this.
1. I tried to pre-order Dying Light for the Xbox One and during checkout the system cancelled my order saying that the store stock had been spoken for. However, I went in once the game released to the same store and was able to purchase the game no problem so in effect I just missed out on my $10 pre-order certificate.I wanted to pre-order but it wouldn't let me - I have never seen this error before.
2. I took advantage of the $39.99 12+1 month Xbox Live Gold gift card you had on sale yesterday. Only the Halo one was abailable at my local store so I ordered 2 of those for pickup. I got home and used the cards and it was only for 12 months not 12+1 as it still says on the website here:
http://www.bestbuy.com/site/searchpage.jsp?st=3878002,+8972116&_dyncharset=UTF-8&id=pcat17071&type=p...
Is there a way to get the extra month advertized?
Thank you!
Solved!
Go to Solution.Hello also_nadrag,
Thanks for writing in, and thanks too for being a My Best Buy member. We appreciate your loyalty. I'll be happy to talk to you about your recent online experiences.
From the sound of things you may have waited too long to attempt a pre-order for in-store pickup for Dying Light. As the order was not able to be processed, I'm afraid we will not be issuing the $10 certificate.
The product description on the Xbox Live Halo card is incorrect in labeling this item as including 1 extra month. As the image online and packaging indicates, this card has an extra bonus for Halo: The Master Chief Collection. We have reported the description error and I hope it is corrected soon. I am sorry for any confusion this may have caused.
Please visit us any time with questions or concerns.
Sincerely,
Mike|Social Media Specialist | Best Buy® Corporate

hi, i can't see anymore the subtitle when i watching a movie on my iPad, somebody can help me with that ?
As has been discussed on these forums thousands of times, Adobe does not make a flash player for iphone/ipad/ipod and likely never will.
You can do a forum search and find countless posts on this. -
Hi I hope somebody can help me.
i had an iphone which was locked to 3 network in UK. after unlocking through network provider, i gave it to my brother to use in india. But unfortunately its not picking up any network availiable in india. When i checked in internet it shows that the phone is unlocked; but the problem persists. he has all the network sims availiabe in my state. I hope somebody can get me out of this trouble..
Could well be that the phone was not unlocked. I would contact 3 http://www.three.co.uk/Store/Phones/iPhone
Failing that you could contact Apple and ask them if the phone has been unlocked

Is there really no one who can help me with my question postet 3 days ago!?
I have a problem with blurry images after publishing -Am I really the only one who thinks this is a big problem -I tried to get some help 3 days ago? Is there other forums that can help me on this topic?
It looks fine in iweb, but not in the browser after publishing... I'ts only with small logo images with hard graphichs in jpeg, its not my compression, it looks fine before publishing...dear wyodor, I thought that I explained my problem all right in my post? well,
when I put a logo in the corner of my site -in my case a jpg file with some text, it looks good in iweb, but after publishing its not possible to read the small text because of the way iweb compress photos - my question is -can I do anything to keep the jpeg-compression i made i photoshop? Is there no way in iweb to control the compression? Its really frustrating -and the only really problem I have with iweb
se how my logo looks im my site:
http://web.mac.com/pierrienevoldsen/24x36.dk/om_24x36.dk.html
I have the same logo twice now just to check different advises, but still its impossible to read the small lettes -but not in iweb -
My Preview opens all my pics at time instead of open one by one. It occurs when I open any JPG FILE. What should I do to fix it? Thanks
First use JPanel not Panel.
Panel panels[]=new Panel[4];becomes
JPanel panels[]=new JPanel[4];Then refactor your code so that you use arrays correctly:
panels=new Panel();
panels.setLayout(new FlowLayout(FlowLayout.LEFT));becomes
panels=new JPanel();
panels[i].setLayout(new FlowLayout(FlowLayout.LEFT));
I did the above changes to your code and it worked fine.

Hello all
i'm a first time user with java...my editor is Visual J++ (trial ed)...i'm testing out java to see if i want to use this for my company. for the past 4 days i've been trying to figure out how to connect to a database (i'm using MS SQL SERVER 2K) i've already posted in the JDBC Fourm...but found no answer...I apologize if I'm posting in 2 different forums at same time...but you gotta feel me on this, over 4 days on just trying to connect is not healthy LOL....
I already downloaded the driver from MS. Installed it followed the user guide (acrobat pdf file) on how to implement it...but i'm still stuck and haven't reached no where....what i want to do is a simple select statement but i can't do that without connecting first....maybe one of you out there has a sample code who uses MS SQL SERVER 2K...or someone can just be a miracle and help out on my code....the code will be attached below

You can try one of these.
By holding down modifier keys while you open the application, you can put Logic Pro or Logic Express into one of several troubleshooting modes. To do this, go to your Applications folder, double-click the Logic icon, then hold down the respective modifier key(s) from the table below until a dialog appears or Logic is fully loaded.
Modifier key(s)
Description
Purpose
Control
Start without Audio
This can be helpful to rule out issues with a specific Core Audio driver. In some cases, Logic may stop responding or quit unexpectedly while initializing the Core Audio driver. In these cases, start Logic Pro or Logic Express without Audio. If needed, turn on Built-In Audio for the troubleshooting.
Shift-Control
AU-Safe Mode
This will only load Audio Units that have passed the Audio Units Validation Tool which is automatically launched on the very first startup of Logic. If you have enabled Audio Units that did not pass this test, you may experience unexpected quitting or misbehavior. With this option, you may revert Logic Pro or Logic Express to a stable state.
Option
Start without Autoload/Template/LastRecent
This will start Logic Pro or Logic Express without loading a Template, Autoload, or last-opened project. This can be useful for troubleshooting any kind of issue since it excludes the possibility that an issue is specific to or caused by the currently loaded project. Choosing File > New with the Option Key held down will load an empty default project for troubleshooting. -

Hi there, hope somebody could help me with this little issue I am having
Hi there,
First of all I want to say that I am very pleased to be part of this community, my name is Juan and I got the following problem:
When my father tries to dial a mobile phone number (from his blackberry) starting with 32, phone adds a plus sign like if he was actually dialing an international number.
I mean, if he dials 321 815 5634, we get the following result: +321 815 5634
Hope someone could give me a clue on how to solve this.
Thanks in advance,
