Why Set does not have get() method

Can some one tell me why set does not have get method?...

user12203354 wrote:
ya u are right that designer of this class thought there is no implementation required for get but why he/she thought like this...
there must be some valid reason for the same.Because a Set's purpose is not to keep things in order; it's to ensure there are no duplicate entries. Set would require extra code to be able to keep track of an order.
Note that there is a Set implementation that does keep track of insertion order--LinkedHashSet--but it doesn't have a get() method.

Test after taking each of the following steps. Back up all data before making any changes.
1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved.
2. Follow the instructions in this support article under the heading "Symptom: The network connection drops unexpectedly."
3. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
4. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
5. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
6. In some cases, the problem has been resolved by repairing permissions on the startup volume.
7. Turn off Bluetooth and test.
8. Reinstall OS X.

The old calender iOS6, in the year view, it shows how much busy I am in a day by indicating the color intensity. But the new calendar year view is totally useless!!! also too bright!! Why apple does this?? What is the way to revert the calendar back???

Unfortunately, that's the way the cookie crumbles nowadays. Sir Jony Ive's GUI design for iOS7 has been met with much skepticism (to say the least). But until the company sees the compelling need for an adjustment or reversal, it "ain't happenin' ". So amble over to the feedback page ( http://www.apple.com/feedback/ ) and make your displeasure known to the company, OR make it known by not purchasing its products. Because as long as the iGadgets continue selling as fast as they can make them, they will see no need for change.
BTW, do note you are NOT talking to Apple here. This is just a user-to-user forum.
Edit: for now, you can also try out any of the alternate calendaring apps available in the App Store.

PO creation-ME21n-Why SAP does not check company code and Plant relation

Hi All,
Does someone know, why SAP does not check Plant and company code relation at the time of PO creation or how can we put validation between plant and company code at the time of PO creation.
<b>Example:</b> Suppose i have a company 0001 which is assinged to Plant 0001. when i am creating a PO with another company code 0002(Entering at header level-Org, data) and using Plant 0001 at line item level. SAP does not do this validation.
How can we put this check in place?
Thanks in advance.
Deepak

Hello Deepak,
There are three types of purchasing
- Company code specific :You need to assign company code to Pur organization
- Plant specific : You must assign plant to pur organization
- Cross company purchasing: No assignment between company code and pur organization.
In the case 3, the system will not check company code and plant relationship, but it will check plant and pur organization specific.
The following is the copy of sap help text:
You can assign a purchasing organization to one company code. This is company-specific purchasing.
You can assign a purchasing organization to no company code. This purchasing organization can then procure for all plants assigned to it, irrespective of the company code to which the plant belongs.
Since each plant must be assigned to a company code, the company code can be determined via the plant in each procurement transaction, even if the procuring purchasing organization is not assigned to a company code.
A purchasing organization must be assigned to one or more plants. This is plant-specific purchasing.
Now, check your company-code and purchase organization assignment.
Hope this helps.
Regards
Arif Mansuri

Why condition does not work.

Hi Pros,
in my bex query, there is a CKF OT hours, having a value 30.000, when I set a condition for 'OT hours = 30.000', but get no result out. could you please tell why condition does not work.

HI,
please check the "Characteristic Assignment" Tab in change condition window.
In that tab default selection as "All Characteristic in the drill down independently" change that selection as "Individual characteristic and Char. combinations" and choose the particular characteristic. for ex OT hours against employee means select employee alone.

When I type my email address in the "To:" field, a random name comes up next to it as "Holidays in United States". This just started happening out of the blue and I have no idea why. Does anyone else have any idea?

Just to recap, this is a collection of ports I have collected over time for people who needed this information when setting up the HP ePrint app so that they could view their email from within the app. I am certain other applications also need this information. Although lengthy, I could not find a more comprehensive place to retrieve this information. Feel free to post additional information, faulty information, or other related topics below as this is simply a collection of data and it would be practically impossible to test all of them. Thank you!

Why Oracle does not allow rollback of DDL statements?

I have always been surprised why Oracle does a implicit commit when DDL statements (e.g create table …) are executed. DDL statements simply write information (insert, delete and update) to data dictionary, so why DDL statement cannot be rolled back. Am I missing some thing?
I was learning SQL Server few months ago and I noticed that SQL Server does allow rollback of DDL statements if I am not mistaken. It lloks like there is something in Oracle architecture which prevents rollback of DDL satements. Rollback of all staements should be allowed not just of DML statements.
Appercaite your insight.

If you drop a 500 million row table (and let's assume you're not using the Recycle Bin, which is a different matter entirely), how do you propose to re-insert all 500 million rows if you were to be allowed to rollback the drop command? Same thing goes for a truncate command.
I'm not saying there aren't workarounds (the Recycle Bin is precisely one of those), but it's certainly problematic. You could very well reverse the transaction ('delete from TAB$...') quite easily... but reversing the other consequences of that transaction is a lot more awkward. Therefore, it is certainly logical to declare such transactions irreversible and thus to imply a commit, both before and after.
Or take it from another philosophical angle: a transaction that doesn't commit (or rollback) takes exclusive row-level locks that are held indefinitely and which will prevent other people from doing DML on the same rows, yes? Well, how do you fancy having an 'alter table' statement sitting around, uncommitted, in the data dictionary? Some process (or your users) are wanting to insert rows into this table, but the uncommitted alter command means that they can't acquire the shared table lock they need in order to be able to do so. One uncommitted DDL can seriously gum up the works, in short.
Dictionary tables are not like ordinary user tables, because whilst what I do in INVOICES very likely has no impact on what you do in SALARIES, what I propose to do in TAB$ very definitely impacts what you might need to do in TAB$. Under those circumstances, it's a jolly good thing that Data Dictionary DDL doesn't leave a trail of uncommitted transactions hanging around! And the mechanism to achieve that 'good thing' (i.e., auto-committing) means such transactions must be immediately irreversible.
Fair enough if other databases have chosen to handle things differently: their prerogative, of course. My point is simply that there is logic in NOT being able to roll back DDL statements, too, and it's a legitimate choice to have made to handle things in this way, too.

JDunlop,
thanks for your quick reply to my java.sun.com forum posting! i just got back from vacation, so i didn't get a chance to try your method til now. i pulled your email address off the website to update you on my problem playing an avi file in JMStudio (JMF).
as per your instructions, i downloaded the divx player at www.divx.com and tried to play the avi file. this is the error the divx player gives:
Divx Player 2.1
The file contains unknown video data
The file contains the following type of data:
Video data: FOURCC code "MP42"
You may need to install a new video codec on your computer to watch this video
Some quick questions:
1. Where could I find the "MP42" codec to play my avi file in JMStudio (JMF)? Does java.sun.com have video codecs?
2. You mentioned in your posting "If you don't have the one that was used in the encoding, your out of luck." Does this mean that I need to know how the avi file was originally coded and have the original codec to decode (play) it?
Thanks,
lac410
P.S. If you need more Duke Dollars for your help, I'd be happy to award them to you.

Author: JDunlop Jun 5, 2003 5:00 AM
sounds to me like you are missing a video codecs. If you don't have the one that was used in the encoding, your out of luck. Download the player from divx.com, it will tell you which codecs the video needs (if it won't play). You can then search the net for that particular codecs.

When I charge my ipod, the apple symbol comes up as if it was turning on, then it goes black and repeats the process. Sometimes it gets to where I have to put in my 4 digit code to unlock it then goes black, any suggestions on why it does this?

Does it work OK otherwise?
Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Try another cable and USB port and/or charging source
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.
