how to get a random alphabet or char ?

[Rahul Sudip Bose]

I want to get a random alphabet or char (and save it as a string, if possible)? Is there anything like Math.random() to do this ?

PS : Any ideas for a beginner level algorithm to make your own random generator which can generate strings,chars etc ? Is this advanced level stuff ?

Not directly...

Consider using String.charAt(int index) method and supply the index by generating random number.

Have you tried to search for it? Because when I type "java math.random" in google, the first hit is the class Math with the method random().

I'll give you a hint: a char is a number. So if you can generate a random number....

I don't think that was what the original poster meant.

I don't know, you can do this exactly like that:

final String alphabet = "1234567890abcdefgh....";
int index = <random index from 0 to alphabet.length() exclusive)>
char randomChar = alphabet.charAt(index);

ya Rob that was what I had suggested.

Thanks for putting it in working code
