Why do we divide a servlet into many methods?

Hello;
sometimes i see that we divide a servlet into many methods...these methods are related with other methods in same servlet and sending parameters to each other...at last all the methods used at least once..and returning variable number is only one...
so why do we seperate these methods?we can do the same job in one method...
i wanted to learn the reason?is it a programming tecnique or the way of creating a library?or related with performance...?
but my question is different...i am asking when all the methods are used in a class why do we seperate them as methods?
thank you

can you post one such example ?

How To Divide Source File Into Smaller Files Without Exporting?

Hello Everyone,
I'm a beginner with PPro CS4 and to video editing in general. I've done a lot of Googling and searching of these forums to get an answer to this question, but I haven't found a clear answer. Here's my problem:
I have many hours of HDV footage shot over the past few years with a Canon HV30. This footage is on dozens of DV tape cassettes. I want to capture most of it to disk.
When I capture a tape to disk, I get a single large mpeg4 file. (PPro captures all HDV footage to mpeg4.) "Scene select" doesn't work with the HV30, so my only other way to make smaller capture files would be to set In/Out points with batch capture. But this would mean hours of fast-forwarding and reversing with the VCR-like controls on the camera to review all the tapes and set the points. I thought it might be FASTER to simply capture an entire tape in one operation, THEN review the captured tape within PPro (it's much faster using the scrubber), and dividing that file into smaller files within PPro, thereby avoiding all the mechanical fast-forwarding and rewinding on the camera itself.
But the only way I can find to do this seems to involve EXPORTING clips. Am I wrong to think that exporting a clip to a new file involves a degradation of the original mpeg4 source file? Or will there be no loss to the quality if I simply export to mpeg4 format?
It seems there should be an easy way to simply divide the original capture into smaller source files for later editing, without putting the footage through another generation of processing (exporting), which might entail some loss of quality. Or am I wrong about this?
(CS4 Master Suite, i7 3630k, 16GB RAM, C: 256GB SSD, D: 1T Setpoint F3, E: 1T Setpoint F3)

HDV footage is mpeg2 (whats in a number ). CS4 does not do scene detect you need to use HDV split for that.
http://strony.aster.pl/paviko/hdvsplit.htm.
You can run your already captured files through hdv split and it will chop the file into clips and off you go.

How do I Display a string from a servlet into a JSP Page???? NEED HELP!!!!

Hi guys,
How do I Display a string from a servlet into a JSP Page...
Ive tried so many bloody things!.....
Simply.
I get text from JSP. The servlet does what ever it does to the string.
Now. Ive create sessions and bean things,.... how the hell do I display it in a text box... I can display on the screen.. but not in the text box.!!!
please help!!!

hmmm, I dont really like using JSP programming, u should be using JAVA..
the way to do it is:
Call and cast to the bean like this:
<%@ page import="beans.*" %>
<% //cast to bean get request create object
userNameBean u= (userNameBean) request.getSession().getAttribute("userNameBean");
then... all you do is call it like this:
<input type="text" name="firstName" value="<%= u != null? u.getFirstName(): "" %>">
this is the real programmers way,,,

Hi guys,

No, and do you know why ? Bcos including a

</body>
</html>
that's the source code....do you have any idea????
Thak's a lottttFrom linxpda:
1) setting the flush="false" parameter for thejsp:include tag?
Here is the problem that I, and perhaps linxpda,
think you have:
You get an exception in the servlet.
You have already written to and flushed the response,
therefore you can not see the exception on your
screen (seeing the exception on screen requires a
send redirect to the error page, which can't happend
when the response is already committed).
The exception that is occuring MAY be alreay written
in your logs, take a look.
To see the problem on screen so as to be able to
identify it, make sure your include tag DOES NOT
flush the buffer. That means change
<jsp:include page="/showCryptValue" flush="true" />
to
<jsp:include page="/showCryptValue" flush="false" />Hi!
No even setting flush false or true it works...If somebody have done this before tell me how have you did....If you can post your code!

I have old video clips in Photoshop Elements Organizer v12 for Mac. I want to divide some of those clips in Organizer. I can do that in Premiere Elements 12 and save them as "Projects" - but how do I get the divided clips back into Organizer?

I have old video clips in Photoshop Elements Organizer v12 for Mac. I want to divide some of those single clips into 2 or 3 separate clips, each shown separately in Organizer. I can divide the clips in Premiere Elements Editor 12 and save them as "Projects" - but I can't find any way to get those divided clips back into Organizer. Does anyone know whether that can be done? Many thanks for your thoughts.

What about Google Drive? And just share the folder with the family members.

Divide a number into random parts

I need to divide a number into a collection of random parts. So that the sum of all parts is equal to the number.
E.g.:
public void divideRandomly ( int number, int parts)
int[] returnArray = new int[parts];
//do random division calculations
return returnArray;
Lets say the number = 20
And parts = 4
I would then like to return an array of ints containing e.g. 3, 11, 5, 1
OR e.g. 4,8,2,6
Does anyone have a clue as to how I could do this?
Cheers

Be aware that given the wrong parameters this solution
can take a long time to find a list. This seems misleading, as the termination condition is based
on randomness. Although, it is possible to predict an average
termination time.
Basically your algorithm starts by generating initial random values
in the range [0, maxValue]. You limit the size of the maximum
generated value, although I'm not sure why. Obviously maxValue
has to be greater than sum / length, otherwise it would be
impossible to generate any combination values that add up to sum.
Then your algorithm asks if the sum of those initial random values
is equal to the target sum. If not, you cycle through the list replacing
the the current position with a new random value and updating the
current sum.
As an example, let's suppose that maxValue is equal to sum, and
that sum = 1000, and length (numParts) is 4.
Assuming the minValue is 1, not 0, then the total number of
permutations of 4 numbers that add up to 1000 is:
165,668,499
However, the total number of permutations is:
1000^4 = 1,000,000,000,000
In terms of probability, the chance of finding a solution on each try is:
165,668,499 / 1,000,000,000,000 = 0.000165668499
Thus, you'll need approximately 6036 loops on average to find a solution for 1,000 split 4 ways.
For 2,000 split 4 ways, number of perms is:
2000^4 = 16,000,000,000,000
The perms of 4 numbers that add up to 2000 is:
1,329,336,999
Probability of finding a solution on each try is:
0.0000830835624375
Average number of tries is: 12036
I'm impressed that the random approach is that fast.

ITunes is dividing my album into several albums - how remedy?

Hi,
Can someone help?
iTUnes is dividing my album into several albums. How can I merge them into one again?
Many thanks in advance!

It usually works to select all of them and put the check next to album # of # track of # (not the actual track #), album artist and any other information that should be the same across the album. this tends to work for me.

How to divide an image into 100+ grids

Hi
I have a problem here;
I need to divide an image into 100 or more grids on client side and I need to get the id of a clicked grid on server side. I found some mapping ways but it seemed too hard to achieve. I achieved to get coordinates of mouse click but this time if user uses control button + mouse scroll, all coordinates of the image changes. Can anyone offer me a solution.

ı am working on adf faces they wanted me to do that on server side. But I am very new at this and I am really confused right now. How can I map 100+ sub images like one big image. I saw some examples on web but they include just two or three mappings but how to do this mapping with many?? I tried to do this by taking coordinates of click and calculating which grid is clicked but everything fails if user resizes the window.
If there is a way to do that I was thinking of storing path of every grid on a list at server side and putting an image on the screen for every element of that list and by this way I could easly get which grid is clicked by just taking the id of clicked image. Can anyone help me to do this.???

Final Cut breaks up video into many separate segments when digitizing --

I'm sure I'm not the only person who's encountered this problem. I'm in the process of digitizing a whole slew of HD video tapes and almost all of them have done so exactly as they should. The only exception is a couple of tapes that are fragmenting into many separate files as they digitize, so instead of one nice big file that can easily be scrolled through in Final Cut, I'm getting three or four dozen different smaller video files, all of which are readable and work but it's obviously not as easy to edit something like that.
Does anyone know why this is happening and how, if possible, to correct it? Is it a video camera setting that was used in the shooting? Or is it some setting in Final Cut that I can change? Or is it merely that the time code on it is corrupt or the tape is somewhat damaged?
Thanks in advance.

When you capture HDV, Final Cut Pro automatically generates a new media file at the point of each scene break. The chosen option in the On timecode break pop-up menu determines how timecode breaks affect the capture; Final Cut Pro disregards the Warn After Capture option to avoid capturing media files that contain breaks in the middle of an MPEG-2 GOP (Group of Pictures).
To determine how scene and timecode breaks are handled when you capture HDV:
Choose Final Cut Pro > User Preferences, then click the General tab.
Choose one of the following options (described below) from the On timecode break pop-up menu:
Make New Clip
This is the default option. Whenever Final Cut Pro detects a scene or timecode break during capture, it finishes writing the current media file to disk and then begins capturing a new media file. It also creates a corresponding clip for each new media file in the Browser. To ensure that all new media files and clips have unique names, it appends a number to the filename of each new media file and clip generated by scene and timecode break detection.
You don't want this checked.

Why cant I drag and drop into playlists

I used to be able to drop and drag inrto playlists. Now I get a message which says press + button to add, but there seems no way of doing it. I'm using windows 7

Apple Support Communities updatesI’ve tried the control-I route and then tried to locate the file without success. What I get as a file location starts with //localhost/C:/Users. It may also be useful to know that most/all the missing files seem to have been copied from CDs. I can’t be sure if it’s all because the whole music file has nearly 9000 entries! The ones that still seem to work were copied from an external hard drive.

why cant I drag and drop into playlists
                                The "missing file" error happens if the file is no longer where iTunes expects to find it. Possible causes are that you or some third party tool has moved, renamed or deleted the file, one of its parent folders, or the drive it lives on has had a change of drive letter. It is also possible that iTunes has changed from expecting the files to be in the pre-iTunes 9 layout to post-iTunes 9 layout, or vice-versa, and so is looking in slightly the wrong place. (In the case of a library moved from one system to another there are also potential permissions issues. See Repair security permissions for iTunes for Windows if this might apply.)
                                Select a track with an exclamation mark, use Ctrl-I to Get Info, then click No when asked to try to locate the track. (Due to a bug in iTunes 12 you currently have to say No twice!) Look on the summary tab for the location that iTunes thinks the file should be. Now take a look around your hard drive(s). Hopefully you can locate the track in question. If a section of your library has simply been moved, a folder renamed, or a drive letter has changed, it should be possible to reverse the actions. If the difference between the two paths is an additional Music folder in one path then this is a layout issue. I can explain further if that is the case.
                                In some cases iTunes may be able to repair itself if you go through the same steps with Get Info but this time click Locate and browse to the lost track. It may then offer to attempt to automatically fix other broken links. Although it says something like "use the same location" it expects to find the tracks in the same artist & album layout that it generates, not all in one big folder.
                                If another application like Windows Media Player has moved/renamed the files then the chances are that subtle differences in naming strategies will make it hard to restore the media to the precise path that iTunes is expecting. In such cases, as long as the missing files can be found somewhere, you should be able to use my FindTracks script to reconnect them to iTunes. See this post for an explanation of how it works.

After I updated to iOS 8, I noticed that while copying photos to my PC, I see photos being categorized into many folders. I also found some system files in each of the folders containing photos (in the name of Local Disk). Is this usual?

I couldn't find the edit button on my original post so I am posting an update here.
I have gone through more apps and have had good luck on all but one more. And it's not that the app doesn't work, I am talking about the Yahoo Weather app, It works fine, but when you swipe between cities the screen lags a bit and it sometimes doesn't move between pages the way it should. On iOS 7.1.2 it was smooth as butter but on iOS 8.0, not so much. I will post a note in the app store to let them know. I really like the Yahoo app better than the new stock app.
I have been going through my games and they all work fine. Angry Birds (Original and Stella), Canabalt, Minecraft, Bejeweled 2, Silly Walks, PopWords, Doodle Jump, Deep Green all seem to work just fine.
Starbucks app works as it should.
I will stop back again next week after I have had the weekend to play with it in detail and post my thoughts again.

Dividing a project into two projects

How do I divide my project into two projects so that I can burn it to a DVD? I have 2hrs 40 mins and this is too long. thanks!

Go to the Project Library View and select your project.
Then FILE/DUPLICATE PROJECT and give the duplicate a name like "your name - part 1".
Then duplicate it again and give the duplicate a name like "your name - part 2"
Now you can open "part 1" as a project and delete everything that is in part 2.
Open "part 2" as a project and delete everything that is in part 1.

Why do we divide a servlet into many methods?
