Hi i just to want to know when we use object casting..

sorry about this newbie question i ve already asked to my tutor but
didn't get it...
i just wonder what will happen if we cast object..
i just can't imagin..coz im just bit slow on creative thinking...
my currently writing code is like this..
Integer nextCustID = new Integer("123456");
Customer customer = new Customer(nextCustID, "Fred");
customers.put("First", customer);
customer = (Customer) customers.get("First");
System.out.println(customer);i don't know about object casting...............................

You don't cast objects. You just cast references - widening or narrowing their "scope" along the inheritance hierarchy.
String s = new String("Hello");
Object o = (Object) s; // Explicit cast not necessary, just for clarification
String s = (String) o;While "hello" might appear as a String, then as an Object, then again as a String, it is always a String. Only the reference type to it changes.

Hi, I just want to know when will be available the new ipod touch

Hi, I just want to know when will be available the new ipod touch

October, as had been said here already literally dozens of times, and stated on Apple's web pages and in the Apple Store quite clearly. If you're asking for a specific date, then again as has been said here multiple times, Apple has not yet announced a specific release date.
Regards.

Ask your government and the wireless providers what is the holdup.
Apple is ready to sell but has not yet gotten approval.

i just want to know when the new ipod touch 5th generation will come out

Apple has not announced any new iPod models. When they do, we'll all find out at the same time, I would guess, since the announcement will be prominent on every Apple-related web site and will probalby be posted in multiple threads in these forums.
Forum Tip: Since you're new here, you've probably not discovered the Search feature available on every Communities page, but next time, it might save you time (and everyone else from having to answer the same question multiple times) if you search a couple of ways for a topic, both in the relevant forums and in the Apple Knowledge Base before you post a question.

You need to find out who the carrier was in Switzerland and see if they will unlock the device. The carrier with the lock is the only one that can authorize the unlock. You may need to check with the original owner and see if they can get it unlocked by the carrier if you do not qualify.

I want to know when I am eligible for an upgrade?

I want to know when I am eligible for an upgrade?

Hi RJ1950. I'm delighted that you're looking into your upgrade. It's an exciting time waiting for a new phone! Both tikibar1 and jimfitzgerald were right, you can log into My Verizon http://bit.ly/xB4iTc and see your phone's upgrade eligibility from the home screen under the usage section. Is there something I can help with while you look into your upgrade?
Thank you

I want to know when my plan is done

I want to know when my plan is up and I want to change my minutes

You should be able to login to My Verizon and there is a link for contract end date. You can also change the minutes on your plan at any time, without extending your contract. You have the choice to backdate the change to the beginning of the current billing cycle (if you are nearing your limit), doing it today or doing it at the start of the next billing cycle. Doing it today is often a bad idea because of the complex pro-ration rules....

I want to know when a sql-query was excuted in DBA_HIST_SQL_PLAN !!

Hi, all.
I want to know when a sql query wqas excuted in past 3 month.
select * from DBA_HIST_SQL_PLAN
where plan_hash_value='1844343569'
is working?
The plan_hash_value is from v$sql_plan of current instance.
There ware 3times database shutdown/startup.
When a oracle instance is initiated, is the plan_hash_value of the same query changing?
Thanks in advance.

You can't go back 3 months unless your retention period is set to that length of time.
select retention from DBA_HIST_WR_CONTROL;
If you want to retain data for longer then you need to modify you snapshots settings, but this can impact your DB if it grows too large.
BEGIN
DBMS_WORKLOAD_REPOSITORY.MODIFY_SNAPSHOT_SETTINGS( retention => 100800);
END;
Then you could get the details out by using something like
select a.SNAP_ID, begin_interval_time, end_interval_time, SQL_ID, PLAN_HASH_VALUE,VERSION_COUNT, FETCHES_TOTAL, EXECUTIONS_DELTA , EXECUTIONS_TOTAL
from DBA_HIST_SQLSTAT a, DBA_HIST_SNAPSHOT b
where b.snap_id=a.snap_id
and b.instance_number=a.instance_number
and sql_id='&sql_id'
;

I saw in my bank account you charge me $ 2.11 just i want to know why?

i saw in my bank account you charge me $2.11 just i want to know why?

These are user-to-user forums, you aren't talking to Apple here and they don't monitor these forums. Is there anything in your purchase history for that amount ?
If you don't recognise the charge then you can contact iTunes support here : http://www.apple.com/support/itunes/contact/ - click on Express Lane, then iTunes > iTunes Store

I have just bought a car with bluetooth and want to know how to use my iphone with it

I bought a car with bluetooth facility and want to know how to use use iphone with it

First, you will need to navigate to the bluetooth interface in your car. Generally, this is something built into the navigation system/entertainment system. Look for an item that says either settings or communication, or bluetooth. If you are having trouble, refer to your car's manual. Next, go to settings, general, bluetooth and change the switch to on. Follow the onscreen instructions in your car until you see something like waiting for device or this is now discoverable or something like that. Your car or some sort of weird name should now appear under the devices list in the bluetooth settings. Now, the car should give you a passcode to type into the phone (it may or may not do this). Type this in and/or follow the rest of the onscreen instructions.
