Method Detail

hasNext

public 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

public int next()

Returns the next element in me.

Returns:

the next element in me

Throws:

NoSuchElementException - if there is no next element

remove

public void remove()

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

Throws:

UnsupportedOperationException - if this operation is not supported

IllegalStateException - if next() has not yet been called, or remove() has already been called since the last call to next().
