Return amount of times a character is in a string?

Hello, quick question. As the title says, how can i return the amount of times a character is in a string? character such as 'a', 'b', etc. Thank you all, appreciate it!

thank you for your help! so would this be correct? (s is the string)
          int amount = 0;
          for(int x = 0; x <= s.length(); x++)
               if (s.charAt(x) == value){
                    amount++;
          return amount;

Program to count the no. of times a character occurs in a string.

program to count the no. of times a character occurs in a string.
Say if u have a method :- Countclass(string s,char c) then using this u should be able to count a char ' T' in the string ="TESTING".
So it is appering 2 times.
How to count it.

int countChar(String s, char c) {
   int count = 0;
   for (int i=0; i<s.length(); i++) {
      if (s.charAt(i) == c)
         count++;
   return count;

Hi Vipin,
You can try below sql code also
code:- len(data)-len(replace(data,'¯','')) -(len(data)-len(replace(data,' ','')))
select data,len(data)-len(replace(data,'¯','')) -(len(data)-len(replace(data,' ',''))) CountofCharacter from

Calculate the number of times a character appears in a string

Please help.
Is there a way to count a number of occurences of a particular character in a string? e.g. If you have 'DATABASE' as a string, can you calculate the number of times 'A' occurs in it? The answer is supposed to be 3, but can you calculate it in Oracle?
Thanks in advance.

Re: Any built-ins for occurance

Count the number of times a character is in a string using pl/sql

I need to count the number of times ":" appers in the string ":XXX:CCC:BBB:".
I have sound some solution using SQL but I do not want the context switch.
Also I am on 10g so I can not use REGEXP_COUNT.
Any help would be great.

Hi,
length(REGEXP_REPLACE(':XXX:CCC:BBB:','[[:alnum:]]'))counts all kinds of punctuation, spaces, etc., not just colons. Change any (or all) of the colons to periods and it will still return 4. Use '[^:]' instead of '[[:alnum:]]' if you really want to count just colons.
Also, "SELECT ... FROM dual" is usually needed only in SQL*Plus or similar front end tools. In PL/SQL, you can call functions without a query, like this:
x := NVL (LENGTH (REGEXP_REPLACE (txt, '[^:]')), 0);

You can search the forums for that error message and find previous discussions - they all boil down to the same problem. Somewhere in your query that calls this function, the code invoked implicitly converts from string to date/datetime. In general,
this works in any version of sql server if the runtime settings are correct for the format of the string data. The fact that it works in one server and not in another server suggests that the query executes with different settings - and I'll assume for
the moment that the format of the data involved in this conversion is consistent within the database/resultset and consistent between the 2 servers.
I suggest you read Tibor's guide to the datetime datatype (via the link to his site below) first - then go find the actual code that performs this conversion. It may not be in the function you posted, since that function also executes other functions.
You also did not post the query that calls this function, so this function may not, in fact, be the source of the problem at all.

Application keeps crashing after an amount of time

Hello,
Since an certain amount of time we get crashes with our application on some of our PC's. It's an touchscreen application and it's running on a builtin PC with an Intel G41 Express Chipset. The application only crashes if it runs fullscreen.
I've tried various things to get a solution but everytime the application keep's crashing. The things i've tried so far:
Reinstall a clean Windows 7 (x86), No chipset drivers (just the drivers Windows recognized) with Adobe AIR 3.6 and the application, after that i've tried Adobe AIR 3.4 and 3.5. Application keeps crashing on the Adobe AIR.dll that's in C:\Program Files (x86)\Common Files\Adobe AIR\Versions\1.0\
Reinstall a clean Windows 7 (x86), the latest chipset drivers with Adobe AIR 3.6 and the application, after that i've tried Adobe AIR 3.4 and 3.5. No other software. Application keeps crashing.
Reinstall a clean Windows 7 (x64) with Adobe AIR 3.6 and the application, after that i've tried Adobe AIR 3.4 and 3.5. Application keeps crashing.
I'm guessing the chipset is messing up Adobe AIR, because if we run it on another PC the application runs fine. Even if I run the application in Windows XP mode, the application runs fine. But I guess that's just because "Windows XP mode" simulates other hardware.
In the Windows Event Log I can find the following entry:

Can someone point the the right direction? If necessary I can upload the whole DMP file.
If you need more information feel free to ask. I'm not the developer of this program so I might get in contact with the company that build this application to get your questions answered.
Many thanks in advance.

Hi Chris,
It seems the problem has been resolved yesterday. I waited to reply with the solution until we're done testing. Since testing is done, i'll tell you our solution. I think the problem was very computer specific, but since others can have this problem i'll tell how we fixed this.
We are using 32" touchscreen from ELO (http://www.elotouch.com/products/ids/3200L/default.asp) with an builtin PC with the following specs.
ECM1:
Intel Celeron Dual-Core
2.2GHz E1500
(512KB L2 cache/800MHz bus)
Appearantly we were using the drivers that are delivered with Windows 7 and we did 'downgrade' the drivers with the drivers that can be downloaded from the ELO website (http://www.elotouch.com/files/driver_packs/IDS_Computer_Module_Win7_Drivers_Package.zip). I guess the below drivers are the one that solved our problem.
* Product: Intel(R) Chipset Device Software
* Release: Production Version
* Version: 9.2.0.1021
* Target Products: Intel(R) 6 Series/C200 Series Chipset Family
*                        2nd generation Intel(R) Core(TM) processor family
* Date: December 23 2010
Unfortunately the latest drivers are'nt always the best... at least not for us.
Thanks Chris for your help, i still can upload the DMP file to see where it was going wrong. I'll email them ASAP.
I hope that I can help some people with this post.

Continuous averaging for a certain amount of time

Hi
In my program I have to use a start button to continuously average a value for a certain amount of time(lets say 3s) and keep and show the average the value. The state of the start button should return to off mode after that 3 sec so if the user hit the start button again it reset the array and calculate the average again.
Would you please help me with this program. I have attached pic of what I ahev done
With this vi I can take data after hitting start for 3 sec but I have these problems:
1- I don't know how to calculate average value when finish getting data after 3 sec
2- I would like the start button back to off mode after 3 sec so if I click on the start button again it reset the array and calculate the average again.
Would u plz help me with this vi?

Use mean function to average an array. And wire your time has elapsed boolean to a case structure and reinitialise your boolean control to default in the true case.
Create invoke node as below, just in case you dont know.

This is Oracle error.
the sql generated is taking lot of temp space. You to tune the SQL.
You can ask the dba to increase the the temp space as well.
Hope this helps.

Is there a way to create a custom screensaver with pics/slides that display for different amounts of time?

Is there a way to create a custom screensaver with pics/slides that display for different amounts of time? Or even add a "video slide" into the screensaver?
My business has 3 TVs displayed in our lobby, each with its own apple TV and they are all linked to the same photo stream. Currently the Atv screensaver displays the photostream pictures of our products for the default 3 seconds. We just added pics/slides that now display messages and useful info for our customers but I want that info to be displayed for a longer period of time than the pictures to give people a chance to read it.
I tried using flickr and powerpoint as a work around but no luck. I created a slide in powerpoint with play length of 15 secs and saved it as a wmv file. I added that file to a "screensaver" set in flickr and pointed the Atv screensaver to that flickr set. It still displays everything, pics and the wmv file at the default 3 sec.
I know I can increase the duration of all pics in the screensaver to display for longer but the goal is to have the pics display at 3 secs and the info slides to display at 15 secs.

Welcome to the Apple Community.
No that's not possible.
If you have any suggestions that you think might enhance the Apple TV you can send Apple your feedback here

Monitoring user logins and amount of time logged in.

I presently have an open directory master with several Mac Pro's authenticating against it. The owner of the Mac Pro would like to do billing to the other departments based on who was logged in and the amount of time they were logged in.
Normally the "last" command would be perfect for this but with the removal of the wtmp file in 10.5 the last command is flaky at best. I will restart its self multiple times per day or not at all for a month so it is hard to write a script to pull the data out of it.
Does anyone know of a way in 10.5 and higher to find out the type of information that the last command displayed, IE who logged in, what time they logged in and what time they logged out.
I need this information for the Mac Pro's but can pull the information from the open directory server if there is a way to get it from their.
Does anyone know where the last command data is being logged since the removal of the wtmp file.

neither of them seem to give me the login and log out times like the "last" command does. Is there not anyway on the open directory server to pull this data?

Amount of time for clients to join a Coherence cluster?

What are some of the factors that affect the amount of time it takes for a client (without local storage) to join the cluster?
We are seeing some tests where the time is a few seconds and other tests where the time is 10's of seconds (up to 30-40 seconds). Would like it to be as deterministic as possible. Any ideas?
Thanks!
Andy

Hi Andy,
We have found that JMX Mbean registration is one factor in startup time, if you have JMX turned on. On joining the cluster, nodes register their MBeans with the MBean servers. If every node has management=all, every node is an MBean server node, whether its needed or not. This can result in an MBean registration storm as every node registers their Mbeans with every other node at startup. Its especially noticable if you have a lot of caches in your cluster. We suggest that only MBean server nodes have the management=all setting to minimize this registration process on startup.

Amount of times i ahev palyed a game

How do I reset the number that counts the amount of times I have played a certain game?

Well, restoring your ipod to its factory settings resets the basic 3 games, not sure about any others though. Dunno about any other ways. '

On iOS 7.0.2 everytime I unlock my phone while my music is playing, it skips. Forward, backward, and by small and large amounts of time.

Hi cowboyincognito,
Thanks for visiting Apple Support Communities.
If you don't have the option to play music by genre on your iPhone, try this step to find the Genre option:
Browse your music library.
You can browse your music by playlist, artist, or other category. For other browse options, tap More. Tap any song to play it.
To rearrange the tabs in the Music app, tap More, then tap Edit and drag a button onto the one you want to replace.
