  • In which way does the code you show not work? Pleas provide a [mre] which demonstrates that. – Yunnosch Mar 08 '22 at 07:08

To generate positive integer numbers you simply need the Random class and invoke the nextInt(int bound) method. This method will return an integer value between 0 and bound-1. If you need a value between a and b, then you can simply add a as an offset of the nextInt result and use (b - a) as the upper bound.

For example:

Random rand = new Random();
int x = rand.nextInt(10);       //returns an integer between 0 and 9
int y = rand.nextInt(10) + 10;  //returns an integer between 10 and 19
