random - In Java how do you randomly select a letter (a-z)?

Question

If I want to randomly select a letter between a and z, I assume I have to use the Random class:

Random rand = new Random();

But since this only generates numbers, what do I need to do to apply this to letters?

Answer 1

Random r = new Random();
char c = (char) (r.nextInt(26) + 'a');
