incrementing characters

[tom brownlee]

hi everyone...can anybody help?
how do you increment a 3 letter / 3 digit command line input so that it prints out the input and the next letter/digit in the sequence???and also the number of sequences left???
ie aaa000 = start of sequence, zzz999 = end of sequence.
eg input 'drg569' prints out 'drg569, drg 570, 17439920 left
( 26*26*26*10*10*10 )
(- 4*18* 7*5 * 6* 9)
( ----------------- )
( 17439920 )
also what about sfz999 to sga000???
any help???

Howdy!
This is probably a silly solution, but you might get it to work for you:

public class Q {
   public static void main(String[] args) {
     StringBuffer sb = new StringBuffer("abc123");
     sb.replace(1, 2, "" + (char) (sb.charAt(1) + 1));
     sb.replace(4, 5, "" + (char) (sb.charAt(4) + 1));
     System.out.println(sb);
 
  }
}

Hope this helps!

Please don't post the same question in multiple forums. It wastes the time of everyone who doesn't realize that a question has already been answered elsewhere. Putting all the answers in one place allows people to build on past answers rather than reinvent the wheel. I'm closing this thread - everyone please see the thread in Java in General (Intermediate) to follow up.
