If you don't know Java stay out of this thread, please.
GENERAL INSTRUCTIONS:
--------------------
Your task is to define a class with one method, described below.
Your class must be defined in a named package placed in the 'src' folder.
You may NOT name the package 'tests' or 'util', but aside from that any
valid Java package name is acceptable.
You may choose any valid Java class name for your class.
You may choose any valid Java method names for your methods. Your methods may
be either static or non-static, but if non-static your class must provide a
no-argument constructor (either the default constructor, or an explicit one).
The functionality of your definitions will be verified by JUnit tests.
IMPORTANT: note that if the methods are simply stubbed out (just return true or
false) then the all the tests for that method will fail. You must provide a
non-stub implementation in order for the tests to have a chance of passing.
HOMEWORK-SPECIFIC INSTRUCTIONS:
------------------------------
A description of the required (public) method:
/**************************************************************************
* @param a String denoting the inputPath the path on the local filesystem
* to the input file
* @returns a HashMap<String,Integer> containing the word->count mappings
*
* This method must read the contents of a file (identified by inputFilePath),
* one char at a time, segment the input into words, and keep track of word
* counts in a java.util.HashMap<String,Integer>.
*
* A word is defined as a contiguous sequence of characters that does not
* contain word separator characters, where word separator characters are:
* ' ' (space), '\t' (tab), '\n' (newline), ',' (comma) and '.' (period).
*
* Think carefully about this definition, and how it applies to an initial
* character sequence not preceded by a word separator, and also a final
* character sequence not followed by a word separator.
*
* You must use only CharacterFromFileReader to read characters from the input
* file. Use it as an Iterator<Character>, keeping in mind the autoboxing &
* unboxing feature of the Java language.
*
* In order to keep your code readable, break your code into several methods.
* Define meaningful private helper methods that you call from the required
* public method.
