Question

Write a program that reads words from a text file and displays all the words (duplicates allowed) in ascending alphabetical order. The words must start with a letter. The text file is passed as a command-line argument. Here is a sample run:

out1.txt File Directly Below... Note: "//notaword" is the part that is not a word and needs to be handled and is specifically the part I am having trouble with

https://www.dropbox.com/s/ume3slnphyhi6wt/out1.txt?dl=0 - link for the out1.txt file for testing yourself

Please include comments as I am in this for learning and would really appreciate the help!

import java.io.File;
import java.io.FileNotFoundException;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Scanner;

public class AscendingOrder {

    public static void main(String[] args) throws FileNotFoundException {
        String fileName = "out1.txt";

        Scanner reader = new Scanner(new File(fileName));

        ArrayList<String> words = new ArrayList<>();

        // while the file has words, keep reading them one by one
        while(reader.hasNext()) {
            String word = reader.next();

            // check if word start with a letter
            if(Character.isAlphabetic(word.charAt(0))) {
                words.add(word);
            }
        }

        // sort the words found
        Collections.sort(words);

        // print the list now
        System.out.println("Words in ascending order:");
        for(String w: words) {
            System.out.println(w);
        }

        reader.close();

    }

}
