IntIterator is used for implementing interval iterations.
It is usually not used explicitly, but through it's special syntax: min...max
While it is possible to assign an instance of IntIterator to a variable or field, it is worth noting that IntIterator does not reset after being used in a for-loop. Subsequent uses of the same instance will then have no effect.
Iterates from min
(inclusive) to max
(exclusive).
If max <= min
, the iterator will not act as a countdown.
Moves to the next item of the iterator.
If this is called while hasNext() is false, the result is unspecified.
