Question

Your method must be non-static and named 'count'. Its return type must be
'HashMap<String,Integer>' and its parameter must be of type 'String'. Your
class must have a no-argument constructor.

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), ' ' (tab), ' ' (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.

Explanation / Answer

import java.util.*; import java.lang.Iterable; public class WordGroup { String words; public static void main(String[] args) { WordGroup plato = new WordGroup( "You can discover more about a person in an hour of play than in a year of conversation"); WordGroup roosevelt = new WordGroup( "When you play play hard when you work dont play at all"); String[] platoArray = plato.getWordArray(); String[] rooseveltArray = roosevelt.getWordArray(); plato.printArray(platoArray); roosevelt.printArray(rooseveltArray); System.out.println("____________________________________________________"); HashSet rooseveltWordSet = roosevelt.getWordSet(platoArray); roosevelt.printArray(rooseveltWordSet); } public WordGroup(String word) { words = word.toLowerCase(); } protected String[] getWordArray() { String[] wordArray = words.split(" "); return wordArray; } protected HashSet getWordSet(String[] groupedWords) { HashSet wordSet = new HashSet(); for (String string : groupedWords) { wordSet.add(string); } String[] wordArray = getWordArray(); for (String string : wordArray) { wordSet.add(string); } return wordSet; } protected void printArray(String[] array) { for (String string : array) { System.out.println(string); } } protected void printArray(HashSet hashWords) { for(String hashset: hashWords) { System.out.println(hashset); } } protected void printArray(HashMap printHashMap) { for(String string: printHashMap) { System.out.println(string); } } protected HashMap getWordCounts() { String[] wordArray = getWordArray(); HashMap wordCounts = new HashMap(); for(String string: wordArray) { int wordCounts.put(string, +one); } return null; } }
