public interface WordFinder
An interface for objects which take a String as input, and iterates through the words in the string.
When the object is instantiated, and before the first call to next()
is made,
the following methods should throw a WordNotFoundException
:
current()
,
startsSentence()
and replace()
.
A call to next()
when hasMoreWords()
returns false
should throw a WordNotFoundException
.
