Help with CIS Lab - Flesch Readability Index

Question

I am a first year computer science student and I need some help with one of our projects. It is working on the Flesch Readibility Index.
We have to create three classes: word, sentence and Flesch (which will include the main method)
The word class has to have the methods countSyllables, getWord and isVowel. We already did that.
The sentence class has to have methods countWords, and nextWord.
We have countWords but are having a lot of problems with nextWord.
As of right now when we call the nextWord() method from the main method, we are given only the first or last word in the sentence. I'm using a string tokenizer to do this.
I need to somehow figure out how to make the method where when it is called it gives one word, remembers the word it gave and then when called again gives the next word because the method cannot be passed any value. It would be a lot easier if I could pass what word I wanted and then just use an array.
Here is what my partner and I have so far:
import java.util.*;
import java.io.*;
* Write a description of class Sentence here.
* @author (your name)
* @version (a version number or a date)
public class Sentence
    String sentence;
    private int tokenCount;
    public Sentence(String s)
        sentence = new String(s);
    public int countWords()
        int numWords = 0;
        boolean prevWhitespace = true;
        for (int i = 0; i < sentence.length(); i++)
            char c = sentence.charAt(i);
            boolean currWhitespace = Character.isWhitespace(c);
            if (prevWhitespace && !currWhitespace)
                numWords++;
            prevWhitespace = currWhitespace;
        return numWords;
    public Word nextWord()
        StringTokenizer tokens = new StringTokenizer(sentence, " .,", false);
        Word test = new Word("");
        tokenCount = tokens.countTokens();
        for (int i = 0; i < tokenCount; i++)
                test = new Word(tokens.nextToken());
        return test;
    public static void main(String[] args)
        Sentence test = new Sentence("The quick sly fox jumped over the lazy brown dog.");
        System.out.println(test.nextWord().getWord());
        System.out.println(test.nextWord().getWord());
        System.out.println(test.nextWord().getWord());
        System.out.println(test.nextWord().getWord());
        System.out.println(test.nextWord().getWord());
}Where the main method gives us:
dog
dog
dog
dog
dogAnother thing is that for nextWord() the return type has to be Word.

Any help you can give would be GREATLY appreciated

Answer 1

Please read the teacher's instructions again. All the information that you need to know is in there. They explicitly state: "use a StringTokenizer as part of the the instance data". Read up on what instance data means. Utilize this instruction and it should fall into place.
