An object which iterates over a collection. An Iterator is used to return
the items once only, in sequence, by successive calls to the next method.
It is also possible to remove elements from the underlying collection by
using the optional remove method. Iterator is intended as a replacement
for the Enumeration interface of previous versions of Java, which did not
have the remove method and had less conveniently named methods.
boolean | hasNext()- Tests whether there are elements remaining in the collection.
|
E | next()- Obtain the next element in the collection.
|
void | remove()- Remove from the underlying collection the last element returned by next
(optional operation).

hasNext
public boolean hasNext()
Tests whether there are elements remaining in the collection. In other
words, calling next() will not throw an exception.
- true if there is at least one more element in the collection
next
public E next()
Obtain the next element in the collection.
- the next element in the collection
remove
public void remove()
Remove from the underlying collection the last element returned by next
(optional operation). This method can be called only once after each
call to next(). It does not affect what will be returned
by subsequent calls to next.
