Generate Random Numbers By Adding 0 Infront SELENIUM

Question

How do I generate a random integer i, such that i belongs 01 , 02 , 03 , 04 and the range gap within 01 to 10. if integer = 10 remove 0 infront.

I tried to use this:

Random generator = new Random();
int i = generator.nextInt(10) + 1;
but it gives me values between [0,10).

But in my case I need them to be (01 , 02 , 03 , 04 , 05) etc.

You should cast your number to String and append 0 if number has one digit. — wawek, Oct 23 '15 at 07:25
Please separate the *number* from the *formatting*. 1) what *distribution* of numbers to you want to generate, and 2) how do you want them *formatted*? — Bathsheba, Oct 23 '15 at 07:27
i want the number that been generate as 01, 02 , 03 , 04 by append 0 infront of it — Ng Kok Zhong Damen NGD, Oct 23 '15 at 07:28

Try:

Random generator = new Random();
int i = generator.nextInt(10) + 1;
System.out.println(String.format("%02d", i));

The is the code snippet:

int i = r.nextInt(10)+1;
String s = String.valueOf(i);
if (s.length() == 1) {
    s= "0" + s;
} 
System.out.println(s);

The int variable will never display the first 0's so you'll have to use a String object :

int i = generator.nextInt(10) + 1;
String s = i == 10 ? "" + i : "0" + i;
