Why its not a good idea to have a return statement in a finally block?
deepak
Finally executes after the try block has finished doing its work--either successfully or not. Finally is only for cleanup that has to be run after try finishes, regardless of how try completes. It's up to the try block to handle the business logic, the real work.
If the real work in the try block says, "return x," then it is not appropriate for finally--the cleanup code--to alter that with "return y" or "throw new Exception()".
If the real work in the try block throws an exception, it is not appropritae for the cleanup code to throw a different exception, or change that to a return.
Remember, if you throw or return from within finally, that will superceded whatever your mode of completion in the try block was.

Hi I think its not a good idea to have "airplane mode" in Control center because if you lost your iphone person who find it could active it easy and you never find it
You can leave Apple your feedback here.
You can disable Control Center on the lock screen here:

I like the new iOS 7 for iphone... But i think it's not a good idea to allow switch the iphone on flight mode when it is locked.. What happens if your iphone is stolen or lost? You couldn't be able to locate it using find my iphone... Can i remove this from the bottom menu?
And have your phone set to require a passcode before it can be accessed.

Plz help why its not compiling ,
hello all i am trying to make the tutorial http://developers.sun.com/mobility/midp/articles/tutorial2/
i have made all the steps once i try to compile it it shows the folowing error:
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
javax.servlet.ServletException: Wrapper cannot find servlet class HitServlet or a class it depends on
at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:836)
at org.apache.catalina.core.StandardWrapper.allocate(StandardWrapper.java:613)
at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:164)
at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:596)
at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:433)
etc.....
i believe the error has something to do with my classpath thats why its not compiling the HitServlet.java
if anybody can show me plz how to make this following step :
Compiling the Servlet
Compiling servlet code is pretty much the same as for other Java development, except for an important twist. Because the servlet API is not a core part of the Java SE platform, you'll need to add it to your CLASSPATH before you can compile servlets.
The servlet API is contained in common/lib/servlet.jar under the Tomcat root directory. Simply add this file to your CLASSPATH and you will be able to compile HitServlet.java using javac. You can edit the CLASSPATH in the system properties or do it on the command line, as this Windows example demonstrates:
C:\>set CLASSPATH=\jakarta-tomcat-4.1.31\common\lib\servlet.jar
C:\>javac HitServlet.java
i have installed the tomcat and its working fine but i dont understand how to set the classpath , i tried to make it in control panel / system / envirement and put the classpath but its still doesnt work
please help on what i should make in my classpath and how to set it to work if not please notify me where am i making mistake thank you

Use of flash buttons - not a good idea?
Hi guys
I've been advised in an earlier post against the use of flash
buttons. As someone relatively new to Adobe products I'm interested
to know how flash buttons don't seem to be supported but flash
moves or indeed flash websites are in abundance and seemingly have
no problems, or personally speaking I've not had problems viewing
such websites in the past. I'm not contending the opinion I was
given but as someone on a learning curve I think it would be
invaluable to learn how one works and not the other.
Also, what would be a suitable alternative to flash buttons,
I'm considering using jpg images which change on mouse-over using
javascript.
Mikesigh - i was trying to be nonjudgemental. one may have a site
where seo is a nonissue and they know that their audience has the
latest flash-equipped browser (like mine, for example. while i
choose to not use flash for different reasons, i don't rely on
search engines as a meaningful source of business and/or leads.)

I have restored my new replacement iPhone from my latest iCloud back up. However my camera roll pictures are not displaying. Its not saying I don't have any pictures in my camera roll, it has all the spaces for them, but it just shows empty white squares? How do I get my pictures back? Thanks!
It's difficult to say whether it's stuck or not as the time to restore a backup can depend on many factors. You'll have to decide when you think it's just not continuing. You could try turning the phone off (hold the power button until you see the red off slider, then slide to turn off), then back on to see if that would get it going again.
When you're convinced it's just hung, you can go back to settings and tap Stop Restoring iPhone to stop the restore. You'll then have to try restoring it again (Settings>General>Reset, tap Erase All Content and Settings, go through the setup screens and when given the option, choose Restore from iCloud Backup). Be sure it's connected to your charger and wifi while it's restoring the backup.
You might also try the approach posted here by ezjules: https://discussions.apple.com/message/19518589#19518589. This seems to have worked for some people who had trouble restoring their photos from an iCloud backup. -

can i change apple id to update a game? if its possible how i can change it? if its not possible why in this generation why its not possible?
You can't. All apps, and any other content from the store, are tied to the account that downloaded them, and they will remain tied to that account - so only the account that bought/downloaded an app can download updates to an app. Are you having problems downloading an app update via the app's own account ?

I'm having problems with Siri on my iPhone 6. It worked briefly yesterday and now its not doing anything. I have turned phone off and on and made sure everything is on in settings. Please help!
Do you have an active data connection (wifi or cellular)? Have you tried resetting the phone by pressing and holding the Home and power buttons until the apple appears (this is different than just turning it off and back on).

Hello, my mail is gone and I can't find it anywhere. Its not in library and I have not configured Time Machine yet. Help please?!
Use Find Any File, if the old messages might have been in a specific mailbox, to look for a file by the name of the mailbox to see if there are any larger versions of that mailbox.
http://apps.tempel.org/FindAnyFile/
If your Mail is indeed gone, you may be able to recover it with one of the data recovery tools here:
https://discussions.apple.com/docs/DOC-1689
But act quickly. Every action while the computer is turned on weakens its chances of recovery. There is a slim chance also your email provider may have tape backup from before you checked your messages and after it arrived at their server for certain messages. You may want to ask them if that might have happened. -

Why are flash buttons not a good idea?
I'm trying to figure out a problem I'm having with flash
buttons (mainly that I don't want users to have to click twice to
make them work), and I keep seeing posts (particularly by Murray)
asking if the poster knows that flash buttons aren't a good idea.
However, I was unable to find an explanation as to
why they are a bad idea. Can anyone explain this to me in
layman's terms? I'm very new to Dreamweaver and web development in
general. I'm developing an intranet site for a specific group of
users where accessibility is not a huge concern.
Thanks!Consider these scenarios -
1. I don't have Flash installed. I don't get the benefit of
your Flash
navigation element.
2. I am a search engine spider. I don't get the benefit of
your Flash
navigation element.
Need I say more? 8)
