public
boolean
hasNext
()
Returns true
if the iteration has more elements.
(In other words, returns true

would
return an element rather than throwing an exception.)
Returns
true
if the iteration has more elements
public

void
remove
()
Removes from the underlying collection the last element returned

. 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.
