Difference between jdk1.3 and 1.4

is there any difference between JDK1.3 and JDK1.4 in terms of size???

I really doubt that adding new lines of code in your program will, by itself and not because of the behavior of those lines of code, cause you to run out of heap space.
More likely, those new lines of code do something in particular which eats up heap space. Also, IIRC an out of memory error isn't just because of the heap; it could also be because of the stack. I'm guessing that those new lines of code contain a runaway recursive method or something like that.
Either that, or perhaps you're doing something really hideous with code generation. My advice about that: don't use code generation.

Difference between jdk1.3 and jdk1.4 and jdk1.5

Hi All
1: I wud like to know the difference between jdk1.3 and jdk1.4 and jdk1.5. I could not recoginze the correct answer for this.. mostly i need the added advantages for version of JDK..
2: I wud also like to know difference in J2SE and J2EE.
Thanks in advance

while I can't tell you exclusively the differences, other than more methods have been added and some have been deprecated, from version to version, that is at least one difference.
I know several like me are reluctant at the moment to jump on up to 1.5, for fear of (and reasonably so) making their current apps go haywire!
Mine did just the other day when I tried to upgrade the JDK from 1.4.0 to 1.4.2.12!! It hosed everything.
J2SE is the Standard Environment, and J2EE is the Enterprise environment, which at the very least allows for things like the java Mail interface, using servlets and classes with the HTTP environment!
I'm sure many other posters could more accurately and specifically give you some other criterion of differences and advantages.

Differences between jdk1.1 and j2sdk1.4 (urgent please)

Someone tels me what are the main differences between jdk 1.1 and j2sdk 1.4 : packages, classes, methods, types ...please. And if there is a package that makes changes to upgrate a code written under jdk1.1 to one that operates under 1.4 or even 1.3 please tell me as quick as possible
Thanks

Yes, that might "generally" be true, but if you want a
list of incompatibilities:
Starting here
http://java.sun.com/j2se/1.4/compatibility.html#incompa
ibilities1.4 (Incompatibilities between 1.4 and 1.3)
you can trace back through the incompatibilities
between 1.3 and 1.2 and the incompatibilities between
1.2 and 1.1.Correct, but I feel pretty safe saying "generally" because of the following paragraph from the above mentioned document:
J2SE 1.4.0 is strongly compatible with previous versions of the Java 2 Platform. Almost all existing programs should run on J2SE 1.4.0 without modification. However, there are some minor potential incompatibilities with 1.3 that involve rare circumstances and "corner cases" that we are documenting here for completeness.

What is difference between sy-tabix and sy-index.

SAP Seniors,
Can you please let me know what is difference between sy-index and sy-tabix.
I read the SAP help, it is confusing for me. it looks like both are same from help. please help me.
Thank you
Anitha.

HI,
Here is a brief description of difference between SY_TABIX and SY_INDEX and using them with several conditions.
SY-TABIX
Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.
APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.
COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.
LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.
READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.
SEARCH <itab> FOR sets SY-TABIX to the index of the table line in which the search string is found.
SY-INDEX
In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.
Hope this helps.
Thank you,
Pavan.

What is difference between sy-index and sy-tabix and where both are using ?

what is difference between sy-index and sy-tabix and where both are using ?

hi nagaraju
sy-tabix is in Internal table, current line index. So it can only be used while looping at the internal table.
sy-index is in Loops, number of current pass. This you can use in other loop statements also (like do-enddo loop, while-endwhile)
SY-INDEX is a counter for following loops: do...enddo, while..endwhile
SY-TABIX is a counter for LOOP...ENDLOOP, READ TABLE...
Here is an example from which you can understand the difference between sy-tabix and sy-index.
Itab is an internal table with the following data in it.
id Name
198 XYZ
475 ABC
545 PQR.
loop at itab where id > 300.
write :/ itab-id, itab-name , sy-tabix, sy-index.
endloop.
My output will be :
475 ABC 2 1
545 PQR 3 2
Sy-tabix is the index of the record in internal table.
sy-index gives the no of times of loop passes.
So, for the first record in the output (475 ABC), 2 is the index of the record in internal table and as it is first time loop pass occured, sy-index value is 1.

The difference between chapter markers and dvd studio pro markers

Does anyone know what is the difference between chapter markers and dvd studio pro markers? I can not find anywhere on Google. Also in the tutorials I have seen, suggesting DVD Studio Pro markers, but it did not mention the chapter markers.
Thanks,

"Adding Chapter and Compression Markers to Your Sequence
Once you have your edited sequence or program finished, you can add markers to the sequence for use on DVD. Markers are reference points you can place within clips or sequences that identify specific frames. There are two kinds of markers you can add that directly relate to authoring a DVD—chapter markers and compression markers.
• Chapter markers allow DVD authoring applications to create a navigable chapter list for your exported QuickTime movie. Chapter markers force MPEG keyframes (known as I-frames) at their location, since the DVD specification requires an I-frame at each chapter point.
• Compression markers identify areas of abrupt change and include two types: those that are automatically inserted by Final Cut Pro at all edit points, and those you manually place in the clip or sequence. Like chapter markers, compression markers force I-frames at their location, although in this case it is for better quality encoding, and they are not used to create a chapter list.
Note: When you export a QuickTime movie, you have an option to export various kinds of markers, including compression, chapter, or DVD Studio Pro markers. *When you choose to export DVD Studio Pro markers, Final Cut Pro actually exports chapter markers and all compression markers.* This includes compression markers you set manually, as well as ones created automatically by Final Cut Pro at edit and transition points."
From the Final Cut Pro User Manual.

The difference between an iphone and an ipod touch?

i want to know if the difference between an iphone and an ipod touch is just that the iphone is like a phone that has internet and is a phone. or what else is it?

The iPhone includes the same as an iPod Touch but also includes a phone, a camera, and a GPS radio.
In addition to having internet access via wi-fi, the iPhone also has internet access via the cellular network, so as long as you have cellular reception with the iPhone, you have access to the internet in addition to having access via an available wi-fi network.

The difference between system restore and last good known configuration

hi,
what is the difference between system restore and last good known configuration.
in which situation you use system restore ,and in which situation you use last good known configuration.
very short answer wil be enough.
thanks
johan
h.david

Last Known Good Configuration deals only with Starting Windows eg. a bad registry or incorrect driver is preventing Windows to start.It recovers the registry settings of HKEY_LOCAL_MACHINE\System\CurrentControlSet
While System Restore uses restore points to return your system files and settings to an earlier point in time without affecting personal files. Restore points are created automatically every week, and just before significant system events, such as the installation
of a program or device driver. You can also create a restore point manually.You can undone system restore but there is no such option in Last Known Good Configuration.
Last Known Good Configuration is disabled in Windows 8 or,Windows 8.1 by default.
Try using Last Known Good Configuration if you can't start Windows, but it started correctly the last time you turned on the computer.
Try using System Restore to return the system to an earlier point in time when things worked correctly.

Difference between sy-uline and uline

Hi All,
Any one of you please update me what is the difference between sy-uline and uline. Also when i give sy-uline in top-of-page event it gives error.
Thanks
sankar

with ULINE u can specify the position from where the ULINE should start
corresponds to WRITE AT 3(10) SY-ULINE.
ULINE AT 3(10) NO-GAP will supress the spacess after the under line
ex : 1
uline at 4(10).
write : / 'My Program'.
uline at 4(10).
ex : 2
write : 'My Program' , sy-uline.

What is the difference between Topic Keywords and Index File Keywords?

What is the difference between Topic Keywords and Index File Keywords? Any advantages to using one over the other? Do they appear differently in the generated index?
RH9.0.2.271
I'm using Webhelp

Hi there
When you create a RoboHelp project you end up with many different ancillary files that are used to store different bits of information. Many of these files bear the name you assigned to the project at the time you created it. The index file has the project name and it ends with a .HHK file extension. (HHK meaning HTML Help Keywords)
Generally, unless you change RoboHelp's settings, you add keywords to this file and associate topics to the keywords via the Index pod. At the time you compile a CHM or generate other types of output, the file is consulted and the index is built.
As I said earlier, the default is to add keywords to the Index file until you configure RoboHelp to add the keywords to the topics themselves. Once you change this, any keyword added will become a META tag in the topic code. If your keyword is BOFFO, the META tag would look like this:
<meta name="MS-HKWD" content="BOFFO" />
When the help is compiled or generated, the Index (.HHK) file is consulted as normal, but any topics containing keywords added in this manner are also added to the Index you end up with. From the appearance perspective, the end user woudn't know the difference or be able to tell. Heck, if all you ever did was interact with the Index pod, you, as an author wouldn't know either. Well, other than the fact that the icons appear differently.
Operationally, keywords added to the topics themselves may hold an advantage in that if you were to import these topics into other projects, the Index keywords would already be present.
Hopefully this helps... Rick

Whats is difference between Java JRE and Java SDK

Hi,
what is the difference between Java JRE and Java SDK...
i think both of them have the same set of files to be installed...
I am not able to understand where they differ

The JRE (Java runtime Environment) contains just the stuff necessary to run Java and the SDK (System Development Kit) contains the extra stuff necessary (and also helpful) to develop in Java.
