This assignment is to write a Java program to:

• prompt the user for a text file name

• read words (a word is a sequence of letters) from the file and count the number of times each word appears.

• display the words along with the corresponding number of times the words appear:

  • in word alphabetic order and

  • in the number of times each word appears order

Requirements:

• Design a separate public class Word satisfying:

  • The class must have 2 private fields (String for a word and int for it's count)

  • The class must override the class Object's equals, hashCode and toString methods

  • The class must implement the Comparable interface using the String field's compareTo method.

• use a JOptionPane to prompt the user for the file name

• store the words and counts in an ArrayList<Word> object.

• use the Collections class sort method to sort the ArrayList<Word>

• display the results on a JTextArea in a JScrollPane in a JOptionPane

• align the words and counts to start in the same column

• use the Collections class sort method to sort the ArrayList<Word> in word count order (a Comparator<Word> object will be needed for this)

• display the results on a JTextArea in a JScrollPane in a JOptionPane

This assignment is due on Thursday June 1^st at the beginning of class. At that time there will be a 10 minute quiz on the assignment. Hand in a printout of the source file and a printout of the javadoc output (the Word html file).
