The method creates a new object and initializes it...
Hello there,
I just started learn the Java, and can't understand the method declaration in "Parameter Types" example at "[Passing Information to a Method or a Constructor|http://download.oracle.com/javase/tutorial/java/javaOO/arguments.html] " tutorial section.
public Polygon polygonFrom(Point[] corners) {
// method body goes here
Can you explain me please the example above, what does "Polygon polygonFrom" means?
And can it be " the method creates a new Polygon object and initializes it", isn't it Constructor's and the new operator job?
Thanks a lot!

Polygon is the return type of the method polygonForm
And can it be " the method creates a new Polygon object and initializes it", isn't it Constructor's and the new operator job?We can't say that it is a constructor and new operator job. Because, As the return type is Polygon, the method should return an object of Polygon or null. For that purpose only the method needs to create a new Polygon object and initialize with some values.

Difference between "clone" and creating a new object
Hi experts,
What on earth is the difference between:
1)creating a new object by using the "clone()" method and
2) just creating a new object?
Let me be a bit more specific:
if there's a class called "Book" and suppose we've already created an object called "japaneseBook", any difference between "Book spanishBook = new Book();" and "Book spanishbook = japaneseBook.clone()"?
Thank you.
EileenThe purpose is very obvious. At anytime in the running application, when Objects have been changed, and you desire to make another one of the same kind, you can't use new. You would use clone. The newer Object would have the same values in the variables. Now i got a question.. an important issue.
public class XYZ{
public static int t = 10;
} // default constructor is present by default.
//In another portion i have the following..
private XYZ x = new XYZ( ); // private Object!!
// Now what about this one????
public XYZ x1 = x.clone( ); // public !!, well
What impact of this code can be there to break the rules of good OOP design??? Is it that a clone Object would have the same access of itself (not of its variables) or different one????????? -
How do I create a new account and get stuff from the old account to the new account
How do I create a new account and get stuff from the old account to the new account
There are instructions on this page for creating a new account : Set up an Apple ID in iTunes
Or if you don't want to give credit card details : Create an iTunes Store, App Store, or iBooks Store account without a credit card or other payment method
But you won't be able to transfer purchases from your old account to it, all content that you download from the store will remain tied to the account that downloaded it. -
It will not parse! Creating a new object in the universe
Hi, we have a universe and BO reports. They work fine for our clients. We are on BO XI r3.1. Now, one client captures an additional piece of info. They would like to report against this and add it high up on our drilling heirarchy. "Sure, no problem". For the following I was logged in as administrator.
The additional data field is a 3 character code.
1) We added an additional column to the actual database table.
2) In Universe Designer, I refreshed universe structure and could see the additional column
3) Created an object 'Acode' that refers to db.new_field
4) Exported universe
Maybe worth mentioning that I can see this object and use it in reports fine in Infoview.
Now, I need to create a new object that will be one of 2 strings based on the 3 character code (Acode) i.e. the 'Atype' can be X or Y.
Here's my code and it just will not parse:
CASE
WHEN @Select(AFolder\Acode) = 'CEL'
THEN 'X'
ELSE u2018Yu2019
END
Error I get is:
Parse failed:Eception:DBD ODBC SQL Server driverStatement could not be prepared.State 42000
I'd appreciate any help, believe me I have searched the forums!
Thanks, EddieLook at following SAP NOtes.

How to create a new variant and a job sheduled to use it for the ......
How to create a new variant and a job sheduled to use it for the exisisting programs
Hi
1. The ALV Grid Control is a tool with which you can output non-hierarchical lists in a
standardized format. The list data is displayed as a table on the screen.
The ALV Grid Control offers a range of interactive standard list functions that users need
frequently (find, sort, filter, calculate totals and subtotals, print, print preview, send list,
export list (in different formats), and so on. These functions are implemented in the
proxy object class. You as the programmer have the possibility to turn off functions not
needed. In most cases the implementations of the standard functions provided by the
control are sufficient. However, if required, you can adjust these implementations to
meet application-specific needs.
You can add self-defined functions to the toolbar, if necessary.
The ALV Grid Control allows users to adjust the layout of lists to meet their individual
requirements (for example, they can swap columns, hide columns, set filters for the
data to be displayed, calculate totals, and so on). The settings (list customizing) made
by a specific user are called a display variant. Display variants can be saved on a userspecific
or on a global basis. If such display variants exist for a list, they can be offered
to the user for selection. If a display variant is set as the default variant, the associated
list is always displayed based on the settings of this variant.
2. REUSE_ALV_LIST_DISPLAY
REUSE_ALV_GRID_DISPLAY
REUSE_ALV_FIELDCATALOG_MERGE
REUSE_ALV_COMMENTARY_WRITE
3. Use of Field Catalog is to determines the technical properties & add formating information of the column.
6. all the definition of internal table, structure, constants are declared in a type-pool called SLIS.
7.fieldcat-fieldname
fieldcat-ref_fieldname
fieldcat-tabname
fieldcat-seltext_m
5. Form user_command using r_ucomm like sy-ucomm rs_selfield type slis_selfield.
Sap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the readability and functionality of any report output. Cases arise in sap when the output of a report contains columns extending more than 255 characters in length.
In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display. This is a very efficient tool for dynamically sorting and arranging the columns from a report output.
The report output can contain up to 90 columns in the display with the wide array of display options.
<b>The commonly used ALV functions used for this purpose are;</b>
1. REUSE_ALV_VARIANT_DEFAULT_GET
2. REUSE_ALV_VARIANT_F4
3. REUSE_ALV_VARIANT_EXISTENCE
4. REUSE_ALV_EVENTS_GET
5. REUSE_ALV_COMMENTARY_WRITE
6. REUSE_ALV_FIELDCATALOG_MERGE
7. REUSE_ALV_LIST_DISPLAY
8. REUSE_ALV_GRID_DISPLAY
9. REUSE_ALV_POPUP_TO_SELECT
Purpose of the above Functions are differ not all the functions are required in all the ALV Report.
But either no.7 or No.8 is there in the Program.
<b>
How you call this function in your report?</b>
After completion of all the data fetching from the database and append this data into an Internal Table. say I_ITAB.
Then use follwing function module.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
I_CALLBACK_PROGRAM = 'Prog.name'
I_STRUCTURE_NAME = 'I_ITAB'
I_DEFAULT = 'X'
I_SAVE = 'A'
TABLES
T_OUTTAB = I_ITAB.
IF SY-SUBRC <> 0.
WRITE: 'SY-SUBRC: ', SY-SUBRC .
ENDIF.
ENDFORM. " GET_FINAL_DATA
The object F_IT_ALV has a field, the activity ACTVT, which can
contain four permitted values: 01, 02, 03 and 70. Each of the
activities 01, 02 and 70 controls the availability of particular
functions (in the menu and the toolbar) of the ALV line item list:
a) 01: "Settings -> Display variant -> Save..."
b) 02: "Settings -> Display variant -> Current..." and
"Settings -> Display variant -> Current header rows "
c) 70: "Settings -> Display variant -> Administration..."
Activity 03 corresponds to the minimum authorization, which is the
most restricted one: The user can only select layouts which have
been configured already. In particular, all of the other functions
named above are inactive with activity 03.
Now if you want to permit a user to change the column selection and
the headers as well as to save the layout thus created, for example,
but if you do not want to permit the user to administrate the
layouts, you grant him or her the authorization for activities 01
and 02.

I used to have a podcast that had been accepted on Itunes, but my I began to have problems with my host, so I changed host and created a new podcast, and I submitted my new podcast, Apple refused, and now says the feed has already been submitted? Maybe Itunes thought that I was someone trying to copy my old podcast because I kept the same name, I tried to change the names but it looks like I'm on a blocked list...
There is a procedure for changing the feed URL for a podcast, which it seems you haven't followed: you have to add a special tag to the old feed - just submitting a new feed will have exactly the effect you describe. The proper method is described here:

I just restored my 13" MBP i5 at the apple store to the newest version of Lion after issues with a previous Time Machine backup from Snow Leopard- this time I created a new account and just ported files and folders, and now MS Office doesn't work.
^^ that's the main problem. Here's the full history.
I bought a new 13" i5 MBP, early 2011 edition. I had an old white Macbook 2.14 ghz core2duo on Snow Leopard. I attempted to port over my time machine backup, but encountered problems in that my User was inaccessible from the new computer after the import finished, and I had to go in and change the root password, etc, and for some reason or another, I couldn't install any programs at all from that administrator's account. By "couldn't" I mean I could install them, but upon installation they would never boot. So, I took it to the apple store and did a clean install from the most up to date Lion OSX. Then, I created a brand new admin account, instead of trying to import the old one, and things seemed great. Then, I just imported my old files from the TM backup, but not any system settings, permissions, or user data. Just my Docs, pics, vids, apps, and itunes stuff.
Here's where things get weird again. I imported this stuff under the name "old", but all of these folders have a red negative sign on them, marking them as restricted. So, from my main admin account, I cannot even peruse these folders. Since I didn't import user data, I can't sign in to the "old" account to change permissions. I already tried to change the permissions from system preferences, but that didn't change anything. And now, for whatever reason, of all the apps that were imported then, MS Office is the only set of apps that does not work. When I click on it, it just says there was a problem and asks if I'd like to send a report to apple. I tried reinstalling it to no avail. I'm an English student, so i really need access to Word. Can anyone help? The Apple store is a major detour for me and would like to fix this issue myself.Most likely you have Office 2004 which are PPC-only applications and will not work in Lion. Upgrade to Office 2011. Other alternatives are:
Apple's iWork suite (Pages, Numbers, and Keynote.)
Open Office (Office 2007-like suite compatible with OS X.)
NeoOffice (similar to Open Office.)
LibreOffice (a new direction for the Open Office suite.) -
How do I move all my files from one User Profile (account) into another?
I needed to create a new account and want all of my files accessible in the new one.ok, what you're learning right now is 101 unix, which is good. Unix is a good thing
now: the way unix works, and macos (which uses unix underneath) the files and folders work like a hierarchy.
the start of that tree is /
so, if you were to do:
cd /
(cd means change directory)
it will bring you at the highest branch of the file system.
cd /Users
will bring you to where all the users are.
to see whats in /Users you can use your friend ls command
ls means list files/directories
so:
cd /Users
ls -la
(the -la here means show all (even hidden) and long format (very verbose)) this flag is very optional.
you will see
fred
user2
for example.
if you want to see the desktop of user2 you would change directory to it then list the files.
for example:
cd /Users/user2/Desktop
Note that the files and directory are case sensitive, so, desktop is NOT the same as Desktop, or DESKTOP
ls -la
you should then be able to see everything in users2 desktop
you could have done as well the same thing in smaller steps, for example:
cd /
cd Users
cd user2
cd Desktop
this is the equivalent of cd /Users/user2/Desktop
So, for your file, i don't know where it was, but know that if you log in as user2, it will directly put you in
/Users/user2
which most likely the file you had created from the other user was in /Users/user1
if you copied all the files from /Users/original_user to /Users/secondUser
most likely yes, all your mail, bookmarks etc would be copied over.
so in your case.
sudo chown -R seconduser:staff /Users/secondUser
should work
Remember that if you start a path with the character / it means start from the root of the file system, at the highest top you can ever get.
so
cd /Users/fred
is not the same as
cd Users/fred
unless you were in / already
i know it may be confusing at first but it's actually very logical if you play with it.
to simplify, think of it that / means C:\ on windows
you can't go any higher than C:\ (in a way)
if you're unsure which directory you're currently in, you can always type:
pwd
it will tell you where you are.
for example:
cd /
pwd
this shows /
cd Users
pwd
this now shows /Users
cd /System/Library
pwd will show /System/Library
cd /
cd /Users
cd fred
cd Library
pwd will show /Users/fred/Library
unix can look very scary but it's actually vital and very necessary to do tasks sometimes that would take for ever to do via the windows. This is good learning.
so for the myfile you had created, i can't tell you where it is, at the time you created, if you can do a pwd command you'll know the path,
ls -la (this shows all the files where you are)
if you see myfile in the list
do a pwd
whatever is return, the real location of the file would be:
whatever pwd returned / myfile
I hope that makes sense. -
Message title says it: Can you copy/paste files from the Finder to Mail in Lion, or drag them onto the Mail icon in the Dock to create a new message and attach the files to it?
I can't find anything in the Knowledge Base that says these two options no longer work or still do.
I do not have a system capable of running Lion, but I need to know the answer nonetheless.Gee, I don't know: "paste attachments mail Lion"? ;-)
One further question, if I may: in Panther (which is where I've aggregated nearly 7 years of mail), if you copy more than one file in the Finder, switch to Mail, and paste the files into a new message, only the file names paste in. If you copy one file and paste it into a Mail message, you get the file, not just the name. Is that still true, or has that (IMHO) bug been fixed since 10.3.9? -
I have downloaded all my music from the cloud to my new iPhone and created playlists so I can listen to it when not it wifi like when on a plane. If I turn on iTunes Match will I still have this music still downloaded? The online information suggests all my music will be replaced. Will I have to download it again??
What you have on your computer is your iTunes library, not an iTunes "account." The account that is related to iTunes is your Apple ID, which you use to sign in to the iTunes Store and make purchases. It is also used with iCloud. iPods (that are not iPod touch) are associated with your iTunes library, not to your Apple ID.
So, I think you probably just need to set up (or update) automatic syncing for the iPod. If it's not set up to sync those new songs, iTunes still syncs the iPod, but it syncs nothing
In iTunes, if the sidebar (along left side of iTunes window) is hidden, from the menu bar, under View, select Show Sidebar. In the sidebar, the iPod appears under DEVICES, when it is connected.
Select the iPod in iTunes. There is a row of buttons, starting with Summary. Click on Music next to Summary. This is the iPod's Music screen, where you tell iTunes how to sync songs to the iPod.
Check the box for Sync Music (if it's not already checked). If your iTunes music library fits completely on the iPod, you can choose to sync Entire music library. Otherwise, you can choose to sync Selected playlists, artists, albums, and genres. On the lists below, checkmark the playlists, artists, albums, and/or genres that you want on the iPod. When you click Apply, the songs from your selection sync to the iPod.
One convenient way to set this up (if you can't sync the entire iTunes music library) is to create a new playlist in your iTunes library. Name it "iPod Songs" (or whatever you want). Put ALL songs that you want on the iPod on this playlist, including those new songs. Back on the iPod's Music screen in iTunes, select this playlist under Playlists. Going forward, to update songs on the iPod, just update that playlist in your iTunes library (add/remove songs). The next time you connect the iPod (or click the Sync button), iTunes automatically syncs the same changes to the iPod. -
I have tried putting music onto it, and it puts it on the playlist, but when I disconnect, it isn't there. I have also tried creating a new user, and still get the error. Please Help!!! Thanx!
Your nano would really have nothing to do with it at that point. It is really something between iTunes and whatever server out there on the internet that it is trying to connect to for the update.
Try posting this one in the iTunes forum, they might have a solution for you.

I created a new collection and put all of my same photos in them as a previous collection, then I changed them to black and white and both collections changed. How do I keep the first collection colour and make the second collection black and white.
For the second collection, choose the option to make virtual copies. Then you can turn the virtual copies to black & white, leaving the first collection in color. If you want file copies of the B & W images you can export copies.
