I feel like it\'s a simple concept, but I\'m having trouble with inclusive and exclusive: particularly concerning random number generator.

Answer 1

For instance, if I wanted a value 2-8 (including 2 and 8), that would be inclusive, correct?

Yes. Inclusive includes; Exclusive excludes.

The range 2-8 inclusive is 7 unique values (2,3,4,5,6,7,8); and Random.nextInt(int) excludes the specified value. So you want something like

Random rand = new Random();
int min = 2;
int max = 8;
// ...
int r = rand.nextInt((max - min) + 1) + min;
