Why we can have only one public class in one source file

why we can have only one public class in one source file

When the java compiler is run it looks for classes referenced by the classes you are directly compiling. When looking for these referenced classes it looks for source as well as class files and compiles them automatically if the coresponding class files are missing, or older than the source.
In order to do this it must be able to work out the source file name for any given class which might be referenced from another (the rule also applies to package level access).

Why a table can have only one PK ?

Just wanted to know the reason why Oracle allows only one PK per table ?
I came across a situation where my existing large PK which is on a single (ID) column needs an alteration to add a new column (No).
ID column on which PK is based is now subjected to have duplication and that is the reason why i want to add a new column. The new column composition is not going to ensure uniqueness.
So, i need to create (alter) PK on two columns now.
It seems, in order to do that, i need to drop the existing PK and create a new one. Since this is a OLTP production database, business cannot afford to drop the existing pk.
When i tried to create a separate PK on two columns, Oracle gave me below err:
ORA-02260: table can have only one primary keySo, i wanted to understand why Oracle allows only one PK / table ? and considering above err, is there any way to make required changes to my PK without altering existing PK?
(Table is a large 30 GB partition table and PK is a non partitioned global index)
I think PROBABLY i need to drop existing PK and re-create the new one. But core intention for opening this thread is to know rational behind one pk/table concept.

It's not exactly Oracle's fault. The ISO SQL standard requires that a "PRIMARY KEY" constraint can only be used once per table. However, a UNIQUE constraint on non-nullable columns achieves effectively the same thing as a PRIMARY KEY. You can have multiple UNIQUE constraints.
Arguably the PRIMARY KEY constraint is unnecessary and could safely be dropped from the SQL language. In principle in the relational model a "primary" key is nothing more or less than a candidate key. All keys are equal in the relational model and there is no fundamental reason to designate a primary key at all. There is certainly no reason not to have multiple keys. In the SQL world though it is a very widely observed convention to use a PRIMARY KEY constraint for each table and to use it for all foreign key references.

Can play only one strack at a time

I recently bought my first Mac. Copied my itunes library from old PC. All seemed fine but I can only play one track at a time. iTunes will not automaticlly advance to the next track in the list in either the library or play lists. I have just installed 7.4.2 but this did not fix the problem. Any suggestions welcomed.

As jere7my pointed out, I think this has to do with the tracks in your library not being checked. To ensure that all of them are, go to the first track in your library, select it, hold down the Apple key and click. Repeat if necessary to enabled (check) all tracks.

Can I combine different parts of one project
yes. you could drop the exported files into a new project.
or if more ambitious, copy and paste the regions into another project. read the tute on rescuing a file, the procedure should give you all the background info you'll need:

Why can we have only one public class in our program

Why is it that we can specify only one class as public in our source code .................................................
Once i'd put one inner class as public ...which means now i have 2 public classes ..............out of which one is the inner class...what is the use of such public class which can be accessed by only its outer class.........

Public inner class can certainly be accessed outside.
You just have to preface it with the name of the outer class.

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).

Only one user at the time can execute VE01 (due to blockage of VEIAV)

Hi,
As I understand it only one user at the time can execute VE01 (or MEIS for arrivals). If someone is already executing the VE01 transaction the error-message "Table VEIAV is blocked by user XX" appears. It does not matter if one tries to execute it for different legal entities - no parallel processing seems to be possible.
This is a huge limitation for a global concern with many entities operating in the same SAP instance. Does anyone recognize this problem and are there any ways to get around it? It does not make sense that dispatches (VE01) and arrivals (MEIS) cannot be executed for several organizational units at the same time in parallel?
Thanks in advance,
Mats Hansson

yes I know this problem.
One should not maintain much thru this transaction.
for me it is not more than an emergency transaction, as it is not really more than table maintenance thru SM30
You should investigate what entries/changes the users have to make.
Limit these manual entries by having better data in the system, so that SAP can itself create the entries for this table.
Organize more, less users , maybe just one per company who shall maintain VEFU manually.
Train them to prepare their entries before they start using VEFU.
Explain that they should leave VEFU as soon as possible as the block other users.
assign maintenance windows to the users.

Cap,
This view, with the one photo big and the thumbnail strip across the top, is what happens when you double-click a photo with "Edit in: Main Window" set in the Preferences. There should be a button visible that says either Done or Return, to exit edit mode and return you to the library. If you still see only one photo, use the size slider in the lower right corner to reduce the photo size and get more thumbnails on the page.
If, for some reason, you can't exit the edit mode, you may have a corrupt preference file. Quit iPhoto. Use the Finder to navigate to Macintosh HD/ Users/ (your user name)/ Library/ Preferences/ com.apple.iPhoto.plist and move that file to the Trash. Launch iPhoto, and you should be returned to the main viewing mode. You'll have to go in the Preferences and reset them to your liking.
Regards.

HT204053 Is there a limit to the number of devices I can have on one account. I have all two of my kids ipods, plus, mine, an ipad, and my iphone, and need to add one more. I do this so that I have control over and can see what they are downloading.

Is there a limit to the number of devices I can have on one account. I have been putting my kids' ipods on my account so that I can manage their downloads, and control it. Then I just create playlists for them specifically. Now, adding another one for my youngest, but have no idea if there are limits.

Well the part about putting songs in the "iTUnes Music" folder I only brought up because it seemed you liked things very organized. You could use iTunes to so all the organizeing. Plus once you add something to the iTUnes library, if you change ANYTHING about it in windows explorer, like its name, change the name of the folder its in or move it to another folder, iTUnes "Looses Track" of it. Its not like other programs that "Watch" files and folders for changes outside its "iTUnes Music" folder
But to have iTUnes auto search, you have to delete a hidden pref file. After doing this, when you open iTUnes again it will throw up a setup wizard, just like its the first time ever installing it. Its in this wizard where you get your ONLY chance to have iTUnes auto search and add files from the system. Just goto the link below and follow Scott P's steps

How to set role which can issue only one command

I am thinking about setting role, which will be allowed to issue olny one command. I have created role test. Which has the following entries in the following files:
/etc/user_attr
test::::profiles=OneCommand;type=role
/etc/security/exec_attr
OneCommand:solaris:cmd:::/tmp/data.sh:euid=0
After this I sill could issue all comands, not only test command /tmp/data.sh.
When I issued comand profiles on test role I received the following:
bash-3.00$ profiles test
OneCommand
Basic Solaris User
All
So I commented line in the /etc/policy.conf to read:
#PROFS_GRANTED=Basic Solaris User
After that, when I try to issue /tmp/data.sh command as a test role I receive the following error:
$ /tmp/data.sh
pfexec: Exec format error
Does anybody know how to set up the role which can issue only one command ? Maybe there is a way to do this in the way which wil not affect another roles (ie, not to touch /etc/policy.conf).
Best regards

AllFirst you need to define what already exists by default. (policy.conf)
Then you get to change those defaults or create a new default list just for test.
Then you get to add a role or profile for test that allows the execution of a profile shell and one command.
Then you should test all of the user accounts to ensure that something didn't break. This step might be a little overkill.

Best way to have only one instance of an object in web application.

Hello,
I defined a class that provides services to my web application: subscribes user, check if user already subscrubed etc. The objects don't need to save any session information. So it is like a Stateless Session Bean (from what I've read about Session beans).
The webapp is small and I don't want to use EJBs.
What would be the best way to have one instance of the above class in my webapp ?
Would making the class static be a good method ? Using a factory ?
Is there a way to put in web.xml something that asks the container to instantiate an object that is not a servlet and place it in Application scope, so that I cann retrieve it whenever required in my app ?
Other suggestions ?
Thank you,
Vlad.

Hi
The best way to have only one instance is use the singleton pattern. The idea is : the class has a private
contructor, a public static method that returns an instance of this object and a static member that is false if not any instance and true if there si an instance.
To obtain one instance you can do some like
MyObject ob=MyObject.getIntance();
this method inspect the static member and returns null if true. If false set to true and return the object
via the private constructor.
