Array Of Random Alphabetic Characters?

Hi,
How would I populate an array with random alphabetic characters? Is there a java defined method for achieving this?
The approach I was going to take was to use Math.random to create numbers between 1 - 26 and use a double scripted array to link the number to a letter.
This is part of a program to test sorting efficiency.
Any help would be appreciated

import java.util.Random;
class find {
     public static void main (String args[]) {
          find f = new find();
          System.out.println("The Random Character is "+ f.myRandom());
     char myRandom() {
          Random r = new Random();
          int i = r.nextInt(52);
          if (i<26) return ((char)(i+97));
          else if(i>=26) return ((char)(i+39));
          else return('0');
}u can do this like this code specified above

HELPwith array of random numbers!!!

can anyone please write up a program that uses an array of random numbers from 0-100 and sort them out...
if anyone can help me that would be great...i tried but i cannot figure it out...
please just write the program so I just have to copy and paste :)

This has to be the most asked question here, or at least it's way up there with classpath and path questions.
Use the search feature to search the forum for random number generation and I swear you'll find more answers and code than you could possibly want.
Good luck

Playlists containing songs with titles starting with non-alphabetical characters do not get transferred at all

I was really happy about how the desktop manager lets me choose the songs from my itunes library by playlists! this is smart! I'm also happy to see the playbook render asian characters properly (unlike my experience on the bold!)
However, I have a lot of songs which have titles that begin with non-alphabetical characters, ie asian characters. For all playlists which contains such songs, those songs do not get transferred onto the playbook AT ALL. For example, I have one playlist which contains only songs with titles beginning with asian characters - this playlist was transferred but it is shown as containing zero songs! When I browse my song library by artist/album, I can find all those songs that should be in that/those playlists.
Can this be fixed?
thanks.
Solved!
Go to Solution.

as it turns out, it kind of got fixed by itself. what i did (i think, since i have not definitively verified) was i went to browse "all songs" wherein i noticed all thoses songs starting with asian characters seemed to show correctly. then i went back to the playlists in question, and viola!
clearly there is a bug or two in the music player somewhere regarding these title characters. but rim has more urgent things to resolve i guess - like my auto screen lock is still not working!

How to fill array with random number?

I need to fill a 3-dimensional array that has user-controlled dimension sizes with random numbers (1-10). I'm unsure of how to do this. I feel like I have to use the initialize array and maybe the build array functions somehow but I'm not entirely sure. Any help would be appreciated. Thanks.

Something like this
Kudos are always welcome if you got solution to some extent.
I need my difficulties because they are necessary to enjoy my success.

How can i type international alphabet characters into keywords, title, and captions in Lightroom 4?

How can i type international alphabet characters into keywords, titles, and Captions in Lightroom 4? Usual Microsoft key shortcuts not working.

I haven't found a way to do that directly, but there is a workaround. It' s a bit cumbersome, so it's only good for the occasional character.
In MS Word or any other text editor create a file that contains all the international characters you need.
When you need to insert one of these characters into Lr (captions, title, keywords) copy the character from your text document and paste it into Lr where needed.
On Windows Ctrl + C / V works fine.

Adobe PDF printer not printing past 180 pages random garbage characters

I am in IT and I have a user whose PDF printer will not convert docs to PDF past 180-182 pages. It gives her an error about that place in the doc that says there was nothing selected and that none of it was converted when in reality it converted it all (up to 180-182 pages). On top of this it will place random illegible characters throughout the PDF with no apparent order. We've re-installed Adobe multiple times and updated it.
I've looked everywhere to find an answer so I'm now here.

A print to PDF is an entirely different process than using the Save As Adobe PDF. If you use the Save As PDF or XPS, you are using the MS plugin, not the one from Adobe. The results can vary depending on the preferences selected and such. Usually when the print fails it is due to either AcroTray not running or an error from Distiller (and recorded in the log as long as the log is not turned off). If you have a lot of graphics, the print process can run into memory limitations (usually from the TEMP folder issue) due to the initial conversion to PS that can be huge. The graphics are generally not compressed much until they get into the PDF.
If you are having problems with the print process, the first step is to try a print to file. This process creates a PS file (may have a prn extension). If that file is created, the next step is to open the file in Distiller to create the PDF. If there are errors from Distiller, you will see them at this step. Errors are often related to color settings or fonts that cannot be embedded. Maybe that will give you some things to consider.

A JTextField that only accepts alphabet characters?

Hi there,
I'm new to java and I'm looking for a way to create a JTextField that only accepts characters. If anyone can maybe show me some code to do this? I've googled and searched these forums for related posts and I found this post:
http://forum.java.sun.com/thread.jspa?forumID=57&threadID=762721
however I haven't the first idea of documents or maskformatters, and my program is meant to be pretty simple. Is there any short way to do this? Or a way of accepting anything, then filtering it and replacing the inputted text with the new text, non-alphabet characters taken out?
Thanks
-Stern

lots of help if you google; for instance adapting some of these ideas may help:

Random wrong characters appear when typing in Firefox--why?

While typing in Firefox, random wrong characters appear (e.g. I type "i" and "n" appears). If I go back and retype it, the same wrong character may appear two or three times, then the correct character appears. This happens while using gmail, but also, for example, when entering search terms into Yahoo. It does not happen while using other browsers such as Chrome, and it does not happen using other applications.

the wrong type characters kept appearing--I
would type the letter i and a 5 would appear instead.
This would indicate you have activated the feature which turns the right side of the keyboard into a numerical keypad. It might be Fn-F6 that controls this -- sorry I don't have a notebook and am not sure exactly how this works.

Truncate byte array of UTF-8 characters without corrupting the data?

Hi all,
I need to be able to determine if the byte array, which is truncated from the original byte array representing UTF-8 string, contains corrupted character. Knowing if the byte array contains corrupted character allows me to remove it from the truncated array.
As in the sample code below, when truncate the string with 16 bytes it displays ok. However, truncate with 17 bytes, the last character is corrupted. Is there a way to check to see if the character is corrupted so that it can be removed from the truncated byte array?
Thanks in advance,
Phuong
PS: The Japanese characters I chose it randomly from Unicode charts. I don't know their meaning so if it is offensive, please forgive me.

Since the byte array is in UTF-8, you can easily examine whether it is corrupt or not by taking a look at the last 4 bytes (at most). That is because the bit distribution of each byte (1st, 2nd, 3rd, and 4th) in UTF-8 encoding is well defined in its spec.
BTW, a Japanese Hiragana/Kanji character typically has 3 bytes in UTF-8, so truncating with neither 16 nor 17 bytes would produce correct truncation.

With exactly which part of this assignment are you having trouble?
Can you create a 2-dim array of characters?
Can you generate a random letter?

How to populate an array with random text files.

I am making a Jeopardy program. I have my program set up so that it retrieves 5 random text files. I just want to know how I populate one array with all the lines from the text files my program is retrieving.

You can read a textfile line by line and add each line to an ArrayList. An ArrayList is very much like an array only that it's "open ended". You can start adding lines without first knowing how many you're going to get. If you still want an ordinary "static" array when you're finished reading lines you can easily get one from the ArrayList and then drop the ArrayList.

How to fill an array with random numbers

Can anybody tell me how I can fill an array with thousand random numbers between 0 and 10000?

import java.util.Random;
class random
     static int[] bull(int size) {
          int[] numbers = new int[size];

          for(int i=0;i<numbers.length;i++) {
harris:
for(;;) {
int trelos=select.nextInt(10000);
numbers=trelos;
                    for(int j=0;j<i;j++) {
if(trelos==numbers[j])
continue harris;
numbers[i]=trelos;
break;
return numbers;
/*This method fills an array with numbers and there is no possibility two numbers to be the
     same*/
/*The following method is a simpler method,but it is possible two numbers to be the same*/

     int[] numbers = new int[size];
Random select = new Random();
for(int i=0;i<numbers.length;i++)
          numbers[i]=select.nextInt(9);

Character Recognition of randomly rotated characters

Hi,
I am working on character recognition algorithm for the images enclosed to this post. The correct order of the two numbers (characters that are needed to be recognized) must be considered. For instance for the first picture the output should be ’23’, for the second ’20 ’ and so on.
My last attempt is attached as well. I am looking for concrete ideas of how to:
- Identify the characters, meaning which tool shell I use (eg. Geometric Pattern, OCR/OCV or something else)
- Do I need to rotate the image in order to aid the character recognition and the order of the characters (numbers)
Thanks in advance,
Zoran

OCR is not going to work for this application. OCR expects the characters to be in a nice straight line, oriented upright. With the large circles in the middle and the random orientation, OCR will just get stuck.
My recommendation would be to train a pattern using standard pattern matching for each character. For the zero, I would include a piece of the circle to get the proper orientation, unless numbers can start with zero. You can quickly do ten searches, one for each character, expecting up to two matches for each (except for zero.) Using the orientation of the characters, you can figure out which one comes first.

How do I generate an array of random numbers that relate to an output wave that falls within a certain frequency range?

I have been creating random numbers that I'm using within a system, the system is working fine, but now I have realised that the random numbers must be outputted to speakers in such a way as to filter out all but a low frequency range.
I was thinking about generating a dither signal with a bandpass filter, but could not get it to give me out a full array of 250 values which I could then manipulate.
The sampling frequency of the output is 200Hz and the 250 data points must fall within the 0-100Hz range.
Another course of action I am considering is to use an FFT and an inverse FFT to get the data that I'm looking for, but I'm fair
ly inexperienced with using labVIEW and can't quite get it to work.
Thanks for the help,
Hank.

As you may already know, in the Functions palette/Analysis VIs/Filters VIs are VIs for filtering. There are also some examples for using these filters under Examples/Analysis/fltrxmpl. You may find some of these are related to your situation, especially for filtering out the higher values.
An option is to simply output the random values to a Comparison/"less than or equal" function, where only values <= to 100 would be sent to an array which is in a For loop. Use the iteration counter of the For loop to count up to 250, at which time you would pass the whole array to your next node. This would let you have 250 values between 0 and 100 for your final array.
Good luck.

Crazy bug - Flash is deleting random string characters

Hello! I'm working through Adobe's "Actionscript 3.0 for Adobe Flash CS4 Professional" book (though I'm using a trial version of CS5). I've run into a crazy error on the 2nd lessons that I believe is out of my control, and wanted to see if the more advanced users had seen it or had any advice.
Everything was going well, when suddenly this bug appeared out of nowhere. It appears that some random characters are getting removed from my strings. For example, when I write the code:
info_txt.text = "Welcome to the home page";
And then run the program, then info_txt just shows: "elmehehmepage", which is the same string minus a bunch of characters. When I try to write the code:
info_txt.text = "abcdefghijklmnopqrstuvwxyz0123456789";
Then it comes out as "aeghilmnprs". This character removal happens for all strings. And it seems that it isn't random, it's just removing a bunch of letters and all numbers, the same ones every time.
Troubleshooting that didn't work:
I thought it might have been something that I did, so I removed ALL actionscript from the project except for the above lines, and got the same result
I tried opening the end-of-the-lesson completed example file that came with the book, and that had the same problem (now I KNOW it wasn't a problem with the actionscript)
Tried restarting Flash CS5, no luck
Does anyone have any ideas what's going on? I can't figure out what made this occur suddenly, and I can't figure out how to undo it.
Thanks!

Dear Friends
I find the solution for this Text Problem....
The Problem is Anti-alias property of the TextField.
by default it will be in "Anti-alies animation".
but for Display the text properly we need to chang it...
In Flash CS5 do the following chantge........
Select Text Field ----> Properties Pallete ----> Anti-alias ---> Use Device Fonts
or
Select Text Field ----> Properties Pallete ----> Anti-alias ---> Bitmap Text[no Anti-alias]
now it will work properly.....
