Assignment Three

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 each word along with the corresponding number of times that word appeared is the file.

Requirements:

• Design a public class Word in a separate file 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 may have other methods such as accessors and modifiers

  • The class must implement the Comparable<Word> interface so that the ''natural order'' is word alphabetic order.

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

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

• Sort the ArrayList<Word> using the Collection class sort method.

• Display the results in a JTextArea in a JScrollPane in a JOptionPane.

• Write a class that implements the Comparator<Word> interface that orders the words in word count order. If two words have the same count then order them alphabetically. Construct an object of this class.

• Sort the ArrayList<Word> again using the Collections sort method using the comparator object from the previous step to sort the words in word count order

• Display the results again on a JTextArea in a JScrollPane in a JOptionPane

This assignment is due on October 10^th at the beginning of class.
