As @Chrisir said, you need to put n = n + 1; after your println().
Let’s imagine n = 2. What you are currently doing is:
- Fill values[2] with a random number
- Add 1 to n so n is now 2 + 1 = 3
- Print in the console the value of values[3]
Since you haven’t defined a value for values[3] yet it will display 0.
What you want is swap the last 2 steps:
- Fill values[2] with a random value
- Print values[2] in the console
- Increase the value of n so n =3 now
