Question

I generate a random number between 0-99 using this :

int num2= (int)(Math.random() * ((99) + 1));

When the number is below 10 I want it to print with a 0num2
So if the number is 9 it would be 09.

How can I get it to print this?

Answer 1

You can use the format() method:

System.out.format("%02d%n", num2);

%02d prints the argument as a number with width 2, padded with 0’s
%n gives you a newline
