Im trying to generate a random letter.... is this possible?

Im try to generate a a random int and convert it to a corresponding char, but im not having the greatest luck...

Any suggestions?? any help will be greatly appreciated!!

ok, sorry i wasnt all to descriptive

I can generate a single random number...

How does one generate a single char?? from a-z

I was thinking , if a random char cant be directly generated, then i could generate a random number within a set range, and wrap it to a char, which would be between the range of a-z...

So to conclude , how do i generate a random char??

thanks!!

and im only just finishing the fundamentals of JAVA, so yes it needs to be in java...

plus it would be great to post this on my ADD/Dyslexia site, as an applet...

Code:
  1. char ch = (char)(random.nextInt('Z'-'A'+1)+'A')


This will we snipprt will generate random character between A - Z

If you want to generate a random string of char then you would need something along the lines of....



Code:
  1. public class RandomCharacters {
  2.  private static void doRandomCharacters() {
  3.      double randomNumber;
  4.      double randomNumberSetup;
  5.      char randomCharacter;
  6.         
  7. System.out.println("----------------------------------------------------------------------");
  9. for (int i = 0; i < 10; i++) {
  10.             randomNumber = Math.random();
  11.             randomNumberSetup = (randomNumber * 26 + 'a');
  12.             randomCharacter = (char) randomNumberSetup;
  13.             System.out.print(randomCharacter + ": ");
  14.             switch(randomCharacter) {
  15.                 case 'a':
  16.                 case 'e':
  17.                 case 'i':
  18.                 case 'o':
  19.                 case 'u': System.out.print("vowel");
  20.                     break;
  21.                 case 'y':
  22.                 case 'w': System.out.print("sometimes a vowel");
  23.                     break;
  24.                 default:  System.out.print("consonant");
  25.             }
  26.             System.out.println(" - Random number was (" + randomNumber + ")");
  27.         }
  29. System.out.println("----------------------------------------------------------------------");
  30.         System.out.println("\n");
  31.     }
  33. public static void main(String[] args) {
  34.         doRandomCharacters();
  35.     }
  37. }


Hope this is along the lines of what you are looking for. You will obviously need to change certain things to fit in with what you want.

Ho-pe this was of help to you.

One last question. How will generating random letters help people with Dyslexia. Would it not be better to randomly geneate words from a pre defined dictionary?

Thanks heaps gordonmcmenemy!!

My first program will , just flash 4 random numbers for a set period of time, into 4 corners of a GUI, 1 number per time...

Then the numbers have to be added up, and entered into a text field, for checking.

The value of the numbers shown increases, and the time they are displayed decreases, as game goes on...

Eye tracking is what makes reading difficult for AD/HD and Dyslexics.... so this gives them a personal benchmark, to be improved apon....

Ive started a blog for people who are wanting to take an active practical approach to beating the negatives of ADD, ADHD and Dyslexia... http://add-icanfocusnow.blogspot.com

I hope this program will inspire , others to do the same...

Thanks very much for your help!!
