public boolean hasNext()
next()
can be called without going past the end of the sequence.
That is, if next()
can be called without deliberately causing an exception.
Note: It is important that the iterator is iterated
past the last element; that is next()
is called
startPosition - endPosition
times. The
get()
or set()
methods should not
be called for the last element.
The default implementation always returns false
.

can be called, otherwise false
