Create a Class for Roman Numerals Create a class called RomanNumeral which has two private instance variables: the String value of the Roman numeral, and an int for the Arabic value. It should have a one-argument constructor that takes a String as a parameter for the Roman Numeral. For this project we will not do error checking. The constructor should set the Roman numeral instance variable, and convert the Roman numeral to Arabic and set the Arabic integer value. Provide get and set methods for the String RomanNumeral and a get method for the Arabic value. Other methods to include are equals, toString, and compare To. Use linked lists to store and sort RomanNumerals Create a class called RomanNumeralList based on the linked list with head node as shown in lecture. The data in the nodes should be a RomanNumeral. Create a class called Unsorted Roman NumeralList that extends RomanNumeralList. It should have an append method that takes a RomanNumeral as a parameter and adds it to the end of the list. Create a class called Sorted Roman NumeralList that extends RomanNumeralList. It should have a method called add which takes a RomanNumeral as a parameter and inserts that word into the list in a position so that the list remains sorted. Read from the file and add to the sorted list For each line in the input file (same file as in project 1), break the line into individual RomanNumerals (Strings) and insert each RomanNumeral into the unsorted list (using append), and into the sorted list (using add). Display the results in a GUI with a Grid Layout of one row and three columns. The first column, as in project 1, should contain the original RomanNumerals, the second column the unsorted Arabic values, and the third column the sorted Arabic values. Submitting the Project. You should now have the following files to submit for this project: Project2.java RomanNumeral.java RomanNumeralGUI.java RomanNumeralList.java UnsortedRoman NumeralList.java SortedRomanNumeralList.java
