Which of the two ways of naming the thread is safer to use? And Why?

Two ways of naming the thread in java
1)
class MyThread extends Thread{public MyThread(String name){super(name)}}
MyThread t = new MyThread("MyThread");
2)
MyThread t = new MyThread();
t.setName("MyThread");

The first example allows you to ensure the thread is given a name, in the second case, the name change is optional.
The difference is a design choice.
IMHO, If you are ever are wondering if some small change will make a big difference to performance then 99/100 times the answer is it wont. In the cases where is makes a difference you are just as likely to get the choice the wrong way around in any case.

HT4341 which of the power adapters can i use in Peru, South America?

Hello:
I'll be travelling down to Peru next month and I need to know which of the power adapters I can use there to charge my laptop. The electricity is 220v in Peru and not 110v like the U.S.

Most Mac equipment these days adapts to 110 Volt 208 Volt or 220 Volt power, 50 or 60 Hz, automatically. For a MacBook, you would need a power cord that ends in the local plug or an adapter from local plug to US standard "parallel two prong, U-ground".
For advice on specific equipment, you would need to post the model, and Readers will try to look it up for you.

When I try to buy something, I get an Apple-ID which is not the one I want to use, and I don't know how to get rid of it either, so that I can use my ID, which is in Mail, Contacts etc. The ID I get, I can't find, so that I can delete it. What to do?

When I try to buy something, I get an Apple-ID which is not the one I want to use, and I don't know how to get rid of it either, so that I can replace it with my ID in Mail, contacts etc. The ID I get without wanting it, I can't find anywhere. I have to delete it. How do I solve this problem, anyone?

My content was obtained through another ID, which popped up earlier. Now this one doesn't pop up, and my current ID doesn't pop up either, but another one. How do you find an ID which is not in the store, and not in Mail, contacts etc. either?
Or is it possible to write the ID yourself when you want to buy something, not only to have it popped up being unable to be changed?

I set up my new computer using the apple ID i always use, and then later migrated all my files from my old mac book to the same new one, but under a different user (same ID). how do i consolidate the two users on my new mac book?

Well if you use the Finder Go menu to Computer, a window opens up double click on your boot drive and then on Users folder, open the other user folder and open Public and drop your files into DropBox
When you do this it will copy them and change the permissions and user assigned to it, so log into the other user and place them into your respective normal folders.
Once you have all your files over and don't need the old user, use System Preferences > Accounts to delete it if you wish, however it's good two Admin accounts on the machine in case something bad happens in the other. Some people for security reasons on use a Standard account for most uses and a emergency Admin account.
One can still do most Admin things in Standard user.

Hi
You need to find the format of the drive by looking at its info, my guess would be you are currently in NTFS (windows only) mac can use any mac os journaled or non journaled, or you can use fat32 which is usable on both pc and mac but is unable to move files over 4GB so no good for large file transfers. You will need to re format at some point but this will delete everything currently on the drive.
Hope this helps

But now , the hole process of sign uping is changed , please remove the wrong guide its not working , and why apple not let to access the free app .!!!

Try going to https//appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Tap edit next to the primary email account, tap Edit, change it back to your old email address and save the change. Then edit the name of the account to change it back to your old email address. You can now use your current password to turn off Find My iPhone on your device, even though it prompts you for the password for your old account ID. Then go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud). Next, go back to https//appleid.apple.com and change your primary email address and iCloud ID name back to the way it was. Now you can go to Settings>iCloud and sign in with your current iCloud ID and password.

Download the updated version of the software can not use and why?

Download the updated version of the software can not use and why?

It will help if you tell us what model of iPod touch you have, how and from where you downloaded the update, what version of iOS this update is, and details about the problem; "can not use" doesn't give us anywhere near enough information on which to base a diagnosis and offer suggestions.

Did you select "Sign In with an Apple ID" as opposed to "Create a free Apple ID" when setting it up?

installing Master collections cs 5.5, the Photoshop failed to install twice and why?

You need to tell us more about your system. We don't even know what operating system you are using, so this is slightly pointless... Also have a look at the install logs and pick out the information we may need.

I just downloaded Firefox 6.0. The web page asked if I wanted to upgrade. What is the most recent version of Firefox and why can't I get it denoted in the propperties link? Also why is it not compatible with AVG Tool Bar?

I just downloaded Firefox 6.0. The web page asked if I wanted to upgrade. What is the most recent version of Firefox and why can't I get it denoted in the propperties link? Also why is it not compatible with AVG Tool Bar?

Firefox 6.0 is the current version.
Get what denoted in what properties link.
You can get the version number in Help -> About Firefox,
and in '''about:support''' typed into the Location bar, and you can use JavaScript to list the user agent -- javascript:navigator.userAgent
I'm not aware of any version of Firefox from Fx 2 on up to Fx 6 where "AVG Safe" is not a problem. Crashes aren't the only failures caused.
