Method Detail

hasNext

boolean hasNext()
Returns true iff I have more elements. (In other words, returns true iff a subsequent call to next will return an element rather than throwing an exception.)

Returns:
true iff I have more elements

next

long next()
Returns the next element in me.

Returns:
the next element in me
Throws:
NoSuchElementException - if there is no next element

remove

void remove()
Removes from my underlying collection the last element returned by me (optional operation).

Throws:
java.lang.UnsupportedOperationException - if this operation is not supported
java.lang.IllegalStateException - if next() has not yet been called, or remove() has already been called since the last call to next().
