Method Detail

hasNext

public boolean hasNext()

Description copied from interface: Iterator

Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)

Specified by:

hasNext in interface Iterator

Returns:

true if the iterator has more elements.

---

next

public Object next()

Description copied from interface: Iterator

Returns the next element in the iteration. Calling this method repeatedly until the Iterator.hasNext() method returns false will return each element in the underlying collection exactly once.

Specified by:

next in interface Iterator

Returns:

the next element in the iteration.

---

remove

public void remove()

Description copied from interface: Iterator

Removes from the underlying collection the last element returned by the iterator (optional operation). This method can be called only once per call to next. The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method.

Specified by:

remove in interface Iterator
