StringBuilder tempString = new StringBuilder();
tempString = tempString.append(Math.random() * (9 - 0 + 1) + 0); 

-I'm trying to assign 9 random digits(one char at a time) to a local StringBuilder object. But its not working. The number I get when I print tempString is:
7897 893. 9660 7073 7313 6326 1

And I want something like so:
7897 8931 4062 1219

Could someone please tell me what is wrong?
Thank you for your time!

-Don't worry about it. Its later appended with something else. This is just a tiny snippet of my program.

I'm creating a credit card number, that tempString is only a part of that number. For example:

 accountNum = tempString.toString();

I also have an issuer ID. when I combine the accountNum(which is a copy of my tempString that I'm working on) I get my whole credit card number (all 16 digits).

I figured it out! Sorry for bothering you. I just had to cast my math.random properly to an int.
But thank you for your time anyway!
