Question

I've done soemthing wrong here because I have no errors, but this program I wrote won't run. Please help to get this to run according to the assignment.

Program Description: Using JavaFX: 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. The text file I'm to nuse is called

example20_1.txt and there is to be an input box for the file and submit button, the file results are to be displayed in an input window below the box and button. This is what I have:

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