Not sure what you mean by the second question, but the answer your first; yes, air 2.6 allows for multitasking. You don't have to do anything to get this to work, it is setup by default.

Please help me in understanding hashcode()

I have some doubt with hashcode(), please help me in understanding.
As it is always advised that whenever you override equals() method, override even hashcode(). As equals() returns the equality of two objects i.e it returns whether two objects are equal or not. The hashcode(), returns int value, i.e if two objects are equal than both hashcode will be same.
Now my question is:
1. When equals() method is comparing 2 objects and returning whethere both are equal or not. Then why we need this hashcode().
2. When this hashcode(), is going to be call?
Please tell me Whatever I understood is right or not....

2. When this hashcode(), is going to be call?
equals() method will implicitly call hashCode() method to compare objects.No it won't. Where did you get that?
Here is the actual code to Strings equals method
    public boolean equals(Object anObject) {
     if (this == anObject) {
         return true;
     if (anObject instanceof String) {
         String anotherString = (String)anObject;
         int n = count;
         if (n == anotherString.count) {
          char v1[] = value;
          char v2[] = anotherString.value;
          int i = offset;
          int j = anotherString.offset;
          while (n-- != 0) {
              if (v1[i++] != v2[j++])
               return false;
          return true;
     return false;
    }Now, where is hashCode called there?

Please help me to understand what is the meaning of Acess point Channel utilization?

       please help me to understand what is the meaning of Acess point Channel utilization? If i want to mange the capacity of my Office Wi-Fi network what are the factor i need to monitor.

Hi Ankit,
Channel Utilization
The 802.11, 802.11b, and 802.11g standards use the same 2.4 GHz band. All must interoperate with each other, which introduces additional overhead reducing channel throughput. Many sites already have products using the Wi-Fi 2.4 GHz band. Additionally, there are many other products that use the same 2.4 GHz frequencies as used by Wi-Fi. Other products include Bluetooth, cordless phones, video game controllers, surveillance cameras, and microwave ovens.
Before the installation of the Cisco Unified Wireless Network, a site can be tested for channel interference and utilization with tools from AirMagnet, Wild Packets, Cognio, and others. The Wireless Control System (WCS) AP On-Demand Statistics Display report provides a spectrum review of the following:
•Noise by channel
•Interference by channel
•Client count versus RSSI
•Client count versus SNR
•Channel radar detection versus time

Please help me to understand Transaction option in SSIS container

Hi experts,
I am confused about Transaction option in SSIS container,
1. Required - Start the transaction. What is mean that start transaction?
2.Supported- join the transaction ..
can you please help me to understand.
Thanks

I think Vaibhav already answered your question but here's more from my end.
1.
Package - Transaction Option - Supported
SEQC - Transaction Option - Supported
3 Execute SQL Tasks - Transaction Option - Supported
So, package / SEQC / SQL 1 / SQL 2 / SQL 3 doesn't involve in a transaction i.e. think of those tasks are not included in
BEGIN TRANSACTION / COMMIT TRANSACTION
Sequence Container
--Execute SQL Task 1
INSERT INTO dbo.t1 (a)
SELECT 10
--Execute SQL Task 2
INSERT INTO dbo.t1 (a)
SELECT 11
--Execute SQL Task 3
INSERT INTO dbo.t1 (a)
SELECT 'aa'
When we execute package, it will insert 10, 11 values into table dbo.t1 and since there's an error in the 3rd statement, it'll fail
2.
Package - Transaction Option - Required
SEQC - Transaction Option - Supported
3 Execute SQL Tasks - Transaction Option - Supported
Now, package will Start a transaction since it's Transaction Option is "Required" , so now the SEQC (3 Execute SQL tasks) will
be inside transaction / join the transaction because their transaction option is "Supported".
Package - Information: Starting distributed transaction for this container. --BEGIN TRANSACTION
(You'll see this statement in Processing / Execution Results tab)
SEQC
--Execute SQL Task 1
INSERT INTO dbo.t1 (a)
SELECT 21
--Execute SQL Task 2
INSERT INTO dbo.t1 (a)
SELECT 22
--Execute SQL Task 3
INSERT INTO dbo.t1 (a)
SELECT 23
Package - Information: Committing distributed transaction started by this container. -- COMMIT TRANSACTION
(You'll see this statement in Processing / Execution Results tab)
When we execute package, it will insert 21, 22, 23 values into table dbo.t1 and also you can see the START TRANSACTION /
COMMIT TRANSACTION in the Exection Results tab are at the Package Level and not at the Sequence Container level.
Without any change, if you change the value from 23 to 'aa' in the 3rd Execute SQL task then you'll see
Information: Aborting the current distributed transaction. statement in the 3rd Executed SQL Task in Execute Results tab
which is at the Sequence container / Execute SQL task 3 level and it's because their Transaction option is Supported and so they
joined the transaction
Please see the screenshot below that under Package, the START TRANSACTION but ABORT TRANSACTION is at Execute SQL task
level
3.
Package - Transaction Option - Supported
SEQC - Transaction Option - Required
3 Execute SQL Tasks - Transaction Option - Supported
Please see the screenshot below that under Sequence Container, the TRANSACTION has started. Since the the Sequence container's
parent (which is package) has not started any transaction and so the it started it's own transaction.
4.
Package - Transaction Option - Required
SEQC - Transaction Option - Required
3 Execute SQL Tasks - Transaction Option - Supported
See the screenshot below which is same as first screenshot.
Since Package's transaction property is set to "Required" and it's Parent to Sequence Container
and so package started the started the transaction, and though Sequence container's transaction option is "Required",
it will not start a new transaction rather it "joins" the transaction that was already opened by it's Parent (Package).
Now, if we see the definitions what Supported and Required means -
Supported - Specifies that this container will not start a transaction.
However, it will participate in a transaction if the parent container started one. This is the default. (4th Example)
Required - Specifies that this container will cause a new transaction to be started unless the parent container already has a transaction,
in which case, the parent’s transaction will be joined. (2nd and 3rd Examples)

SQL*PLUS using START command - please help me to understand

Hello dear friends,
I met one issue that i can't understand. Could you please explain me what is wrong in my logic.
I have created sql file called DUMMY.sql
the file context is:
SELECT dummy
FROM dummy_tbl
WHERE dummy_col=&dummy_var;
I go to SQL*Plus DB version (10.2.0.4.0).
I promt command: START DUMMY 1
and expecting *&dummy_var* to be replaced with *1* and query be executed as it is described in Oracle SQL*PLUS reference ([http://download-west.oracle.com/docs/cd/B12037_01/server.101/b12170/ch6.htm#sthref1058|http://download-west.oracle.com/docs/cd/B12037_01/server.101/b12170/ch6.htm#sthref1058] ).
But instead i'm getting Enter value for dummy_var:
please help me to understand
thanks in advance.

You need to use &1 instead of &dummy_var.
The number references the position of the parameter to use;&1 is the first parameter, &2 would be a second parameter and so on.
SELECT dummy
FROM dummy_tbl
WHERE dummy_col=&1;

Please help me out with something simple.

I know this is simple probably to figure out but I really want to make sure that I do this correctly.
So please if someone could tell me exactly how to get my ipod working.
Do I need to re-install itunes if I had it on here for my old ipod?
And when do I set up my ipod to be charged and all?
Do I launch itunes first and then plugg in my ipod?
I know this must be really an anoying question, but I just want to be safe.
Thanks
? Windows XP ?

Let me take a whack at this and see if I can help at all.
Do I need to re-install itunes if I had it on here for my old ipod?
itunes is not ipod specific. You can update multiple ipods with the same itunes library. Now ipods are itunes library specific though. If you try to sync your ipod with a separate itunes library without having it sync manually, it will erase all your media and replace it with the current library.
And when do I set up my ipod to be charged and all?
Your ipod will charge whenever it senses a viable charge input (usb connection, wall charger, car charger)
Do I launch itunes first and then plugg in my ipod?
You can, but you don't have to. When you open itunes, it will search for any ipods plugged into your computer. There is also a setting in which you can have your ipod automatically open up itunes for you when you plug in your ipod.
I hope this helps

Someone please help me to understand

This was a 'brief' tutorial implementing callbacks in Java, i cant undersand what is going on, can anyone help. Its designed to illustrate interfaces. I know how interfaces work so you dont have to explain that. Thanks so much
public interface InterestingEvent
public void interestingEvent ();
This gives us a grip on any objects of classes that implement the interface. So, we need not concern ourselves with any other extraneous type information. This is much nicer than hacking trampoline C functions that use the data field of widgets to hold an object pointer when using C++ code with Motif.
The class that will signal the event needs to expect objects that implement the InterestingEvent interface and then invoke the interestingEvent() method as appropriate.
public class EventNotifier
private InterestingEvent ie;
private boolean somethingHappened;
public EventNotifier (InterestingEvent event)
ie = event;
somethingHappened = false;
public void doWork ()
// Check the predicate, which is set elsewhere.
if (somethingHappened)
// Signal the even by invoking the interface's method.
ie.interestingEvent ();
In that example, I used the somethingHappened predicate to track whether or not the event should be triggered. In many instances, the very fact that the method was called is enough to warrant signaling the interestingEvent().
The code that wishes to receive the event notification must implement the InterestingEvent
interface and just pass a reference to itself to the event notifier.
public class CallMe implements InterestingEvent
private EventNotifier en;
public CallMe ()
// Create the event notifier and pass ourself to it.
en = new EventNotifier (this);
// Define the actual handler for the event.
public void interestingEvent ()
// Wow! Something really interesting must have occurred!
// Do something...

It looks to me like EventNotifier is a class that detects some event and notifies another object that the event occurred. When an EventNotifier is created, an object that implements the InterestingEvent interface is passed and is referenced thru the ie variable. When EventNotifier detects the event, it calls the interestingEvent() method of the object implementing the interface.
This is similar to how ActionListener/ActionEvent works. It would make more sense to me to call the interface InterestingEventListener.

Creative, please help to figure out something

Hi. Im asking creative support, not forum members, etc...
The story looks like this.
I bought motherboard MSI K8N Diamond with Creative Li've! 24-Bit. Nice chip, nothing to say. But i got one little problem. This kind of platform supports 64-Bit systems. The problem is thats no driver for this. Yes, i know thats this question already asked alot of time on this forum. But this is not the point. I want to know WHERE i need to ask for support, here on Creative site(forum) or at MSI site? Why im asking? Because MSI says go to Creative and ask there. Looks pretty stupid for me, because i paid to MSI and not to Creative, why should i bother Creative now?
Anyway if you guys got any info when driver for 24-Bit x64 gonna be released please post the date here.
Please answer to both of my questions.
Thanks beforehand.

To contact our Support you do need to go to the Contact Us > Customer Support page. This forum is, as detailed in the announcement at the top of each page, primarily intended for customer interaction, for people to discuss topics and help eachother. Support is available through the normal channels (phone, e-mail).
As far as motherboard audio goes, this is generally supported by the motherboard manufacturer, so they should be your first point of contact in this case. I don't have any information on a release date for full drivers for the (retail) SBLi've! 24-bit, but it's best to keep an eye on these forums and the download pages for updates. Any current XP64-bit drivers are available through the Preview site.

Please help me in understanding the following code.

public static void main(String args[]){
int x=0,c=0;
for(int i=0;i<3;i++)
x = x + x++;
System.out.println(x);
why this program always prints zero(0) as output. I am not able to understand the execution sequence of it.

bkyadav wrote:
at certain point of time in porgram
(x++) should be treated as x = x+1; but that is not happening.Here's the rule : you have to proceed the expression from left to right.
For example :
int x = 8;
x = x + ++x; // x = 8 + 9 = 17
int x = 8;
x = x + x++; // x = 8 + 8 = 16
int x = 8;
x = x + --x; // x = 8 + 7 = 15Also, in the for statement of your example :
for(int i=0;i<3;i++)the value of i+ is first tested before being incremented for the next iteration otherwise the test on value of i+ = 0 would have been skipped.

Please help me in understanding relationships in SQL

This is according to
*"One-to-one relationships occur when there is exactly one record in the first table that corresponds to exactly one record in the related table."*
One-to-one relationships are single-valued in both directions.
My understanding with the above is that
Consider a Zip Table
ZipNo Studentname
12 Harry
13 Kiran
A Student Table
ID Name ZipNo
101 Harry 12
and there should not be any more student with zipno 12 . Then this will be a One to One
Am i right ?

Hi,
what you have given is table design. as per your design is one to one table design. where is SQL is there.
