What is the diffrence between extends and creating new object?

HI ALL,
what is the diffrence between extends and creating new object?
meaning
class base{
class derived extends base{
class base{
class derived {
derived(){
base var = new base();
can u people tell me diffence from the above examples.
THANKS.
ANANDA

When you create a new object you have to supply the class to which that
object belongs. A class can extend from another class. If it does so
explicitly you can define the 'parent' class from which the class extends.
If you don't explicitly mention anything, the class will implicitly extend
from the absolute base class named 'Object'.
Your example is a bit convoluted: when you create a Derived object,
its constructor creates another object, i.e. an object from the class from
which the Derived class extends.
Extending from a class and creating an object don't have much in common.
kind regards,
Jos

What is the diffrence between ASCII and BIN mode

Hello All,
What is the diffrence between ASCII and BIN mode
Regards,
Lisa.

'ASC' :
ASCII format. The table is transferred as text. The conversion exits are
carried out. The output format additionally depends on the parameters
CODEPAGE, TRUNC_TRAILING_BLANKS, and TRUNC_TRAILING_BLANKS_EOL.
'IBM' :
ASCII format with IBM codepage conversion (DOS). This format correspond
to the 'ASC' format when using target codepage 1103. This codepage is
often used for data exchange by disc.
'DAT' :
Column-by-column transfer. With this format, the data is transferred as
with ASC text. However, no conversion exists are carried out and the
columns are separated by tab characters. This format creates files that
can be uploaded again with gui_upload or ws_upload.
'DBF' :
The data is downloaded in dBase format. Because in this format the file
types of the individual columns are included, import problems, for
example, into Microsoft Excel can be avoided, especially when
interpreting numeric values.
'WK1' :
The data is downloaded in Lotus 1-2-3 format.
'BIN' :
Binary format. The data is transferred in binary format. There is no
formatting and no codepage conversion. The data is interpreted row by
row and not formatted in columns. Specify the length of the data in
parameter BIN_FILESIZE. The table should consist of a column of type X,
because especially in Unicode systems the conversion of structured data
into binary data leads to errors.

What is the diffrence between BAPI and RFC and business object

Hi Experts,
Can anybody tel me what is the diffrence between RFC and BAPI , and also what is ther relation with business object?
Thanx in advance.
Nilesh Hiwale

Hi,
BAPI's are associated with Business Objects and also they are RFC enabled.
But RFC's are the FM's which can be called from external systems, those FM's can be used in many places based on the applications..

What is the diffrence between PGA and UGA?

Hi All
Just one question
"What is the diffrence between PGA and UGA?"
Thanks

PGA Memory
The Program Global Area (PGA) is a memory region that contains data and control information for a single process (server or background). The PGA is made up of the following:
Stack Space
A PGA always contains a stack space, which is memory allocated to hold a session's variables, arrays, and other information.
Session Information - (UGA)
A PGA in an instance running without the multi-threaded server (named Shared Server in Oracle9i) requires additional memory for the user's session, such as private SQL areas and other information. If the instance is running the multi-threaded server, this extra memory is not in the PGA, but is instead allocated in the SGA (the Shared Pool).
Shared SQL Areas
Shared SQL areas are always in shared memory areas of the SGA (not the PGA), with or without the multi-threaded server.
Non-shared and Writable
The PGA is a non-shared memory area to which a process can write. One PGA is allocated for each server process; the PGA is exclusive to a server process and is read and written only by Oracle code acting on behalf of that process.
UGA Memory
The UGA, or User Global Area, is allocated in the PGA for each session connected to Oracle in a dedicated server environment. The PGA is memory allocated at the client to hold a stack which contains all of the session's variables, etc. In a Shared Server environment, Oracle allocates this memory in the Shapred Pool (the shared pool is contained in the SGA), for all sessions. This helps to reduce the PGA (client) memory footprint of Oracle, but will increase the SGA (shared pool) requirements.

What is the diffrence between multicasting and broadcasting?

hi friends
What is the diffrence between multicasting and broadcasting?
i'm bit confused in multicasting and broadcasting.

Broadcasts go everywhere within a range determined by the sender.
Broadcasting is deprecated and unliikely to go beyond the nearest router.
Multicasts go everywhere where receivers have declared they are present.
Multicast can be implemented beyond routers in a WAN which you control but ISP routers generally don't support it.

What is the diffrence between map and map.entry in core java

what is the diffrence between map and map.entry in core java . where it will be use ful. any one give one example plz.

A Map contains Map.Entry's
e.g.
        Map map = new LinkedHashMap(8);
        map.put(new Integer(1), "one");
        map.put(new Integer(2), "two");
        final Iterator iterator = map.entrySet().iterator();
        while (iterator.hasNext()) {
            Map.Entry entry = (Map.Entry) iterator.next();
            System.out.println("key=" + entry.getKey() + ", value=" + entry.getValue());
        }

What is the diffrence between OCI and OCCI?

What is the diffrence between OCI and OCCI?

Will Lee wrote:
What is the diffrence between OCI and OCCI?Beside the other answers, there are a few additional points to consider:
1) OCI is the "gold" standard API. New stuff is always available in OCI first, and only later trickles down to other APIs, like OCCI.
2) OCI is a low-level API, harder to get started with, than OCCI. APIs in OCI are often "untyped", taking a void*, which opens the door for errors.
3) In OCCI you set values, while in OCI you bind them. So OCCI takes a copy of your values, while OCI takes an address at which to later read the value. This opens the door to subtle bugs where you pass the address of a temporary in OCI, which later crashes in some mysterious ways. So OCCI is way safer in this regard.
4) OCI is C code, which is very portable. Because OCCI is C++ code, and on Windows you can't easily mix and match libraries compiled with different versions of Visual C++ (VC6, 7, 8, 9), you have to wait for Oracle to make a new build with the latest MS compiler. Just see the number of questions on this OCI forum and the OCCI one.
5) OCI is used internally by Oracle to write many of their own tools, it's the lingua franca between the Core DB group and the other groups. Since they use it themselves, it's much more stable that OCCI, which is mostly only used by outside customers.
6) The way SQL objects are dealt with in OCI and OCCI is fundamentally different, to the point where you can't mix and match OCCI and OCI object calls.
#1 above is one reason we had to abandon using OCCI, lacked support for the new in 11g BinaryXML, but that's just one example.
IMHO OCI is the way to go, if you want the latest and greatest. Yes, it's more difficult to code against, so the learning curve is steeper, but once you've reached critical mass it's just fine. If you write code in C++ as opposed to C, you can easily make it a lot safer with a thin C++ layer on top which, unlike OCCI, still allows you access any OCI raw handle to do stuff the wrappers don't expose.

What are the differences between inactive and active ABAP objects?

Can anybody tell me what are the differences between inactive and active ABAP objects?
In my opinion, an active object is compiled and system wide available, that means the system do not have to compile the program again before run or use the object. While An inactive object is not system wide available and every time you run an inactive object, firstly the abap runtime will have to generate a tempory runtime object and this inactive object can not seen by others.
Am I right? Can anybody kindly tell me other differences?

Hi,
"When it is inactive, it is like it would not exist at all:" no - it's like it only exists to you
"If we just saved that one means it is stored in application server not in database": no - the inactive version is also stored in the database. You can log off and log on and it will still be there, in its inactive status.
"Only active objects can be executed.": no - inactive objects can be executed by you
When you create or modify a program, it is inactive until you activate it.
With a change, there are two versions of the program stored in the database - the active version (as it was before you made your change), and the inactive version. If you attempt to run the program, you'll run the inactive version - the one with your changes. Everyone else on the system will run the active version.
In this way, you can make changes without affecting anyone else.
Once you activate your program, then the inactive version becomes the active version.
With a create, there is no active version, until you hit the activate button. This means ONLY you can run the program.
An additional benefit of this model, is that if you make a change, save it, and then change your mind without activating, you can recover the active version into the editor, using version management.
A downside is that sometimes you have to activate your change before you can test it, if it interacts with other, active, programs.

Kumar

What is the Diffrence between Adaptive and Webi Job Server

Hello,
What is the diffrence between Adaptive Job server and Webi Job server?
In my BO server we didn't have Webi Job server but we are able to schedule the webi reports successfully.
Any Idea on this.
Thanks,
Nimesh.

I believe the Adaptive Job Server is on a generic shell server that behave as a Webi Job Server when it processes webi reports, as a program job server when it processes program object etc.

What is the diffrence between cookies and cache, is it safe to remove cache?

what is the difference between cookies and cache , is it safe to remove cache ? . I had cleaned cookies many times but I have not removed cache , does it goes on increasing day by day ? please let me know

Cookies are small files that contain information useful to a web site -- such as password, preferences, last date visited, etc. You may remove the cookies that you don't want adn since some of them are a privacy issue, many people remove them all.
Cache is just a collection of data downloaded to help display a web page. After you leave a site, much of the cache is left on your computer and is no longer needed. You can always remove the cache because it will be replaced as needed.

What si the difference between crete and create insert operations.

Hi
In ADF 11g,what is the difference between create and createinsert operations.
if anyone knows plz tell me.Any document about this plz provide me.
Any help is appreciated.
Sailaja.

Hi,
CreateInsert: Creates a new row that becomes the current row, and inserts the
new blank row into the data source.
Create: Creates a new row that becomes the current row, but does not insert it.
--> normaly you would use createinsert
Doc you can find here (search for Createinsert): http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974.pdf
