Iterator

Fields Summary

Constructors Summary

Methods Summary
public boolean	hasNext() Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.) return true if the iterator has more elements.
public E	next() Returns the next element in the iteration. Calling this method repeatedly until the {@link #hasNext()} method returns false will return each element in the underlying collection exactly once. return the next element in the iteration. exception NoSuchElementException iteration has no more elements.
public void	remove() 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. exception UnsupportedOperationException if the remove operation is not supported by this Iterator. exception IllegalStateException if the next method has not yet been called, or the remove method has already been called after the last call to the next method.
