Questions about the code follow the code listing. The source for the code is in SimpleWordCount.java. 

import java.io.*;
import java.util.*;

public class SimpleWordCount {
    public static void main(String[] args) throws FileNotFoundException
    {
        Scanner in = new Scanner(new File("test.txt"));
	in.useDelimiter("\\Z");
        String text = in.next();
        String[] words = text.split("\\s+");
	System.out.println("Total # words = " + words.length);

        for (int k = 0; k < words.length; k = k + 1) {
            System.out.println(words[k]);
        }
            
    }
}
Below is the result of running the code with test.txt.
