Write a main application called Project1.java, and a GUI (that extends JFrame) called RomanNumeralGUI.java. The main program should open a file called “input.txt” which will contain Roman numerals. There may be more than one Roman numeral on a line, and they will be separated by commas.
The GUI should have a grid layout of one row and two columns (column 0 and 1). Column 0 should contain each individual Roman numeral from the file. Column 1 should have corresponding lines that give the Arabic value of the Roman numeral. For example, if the input file contains
IX
MMXXIII,VII
Then the content pane of the GUI should contain

The core of this project is the conversion of a Roman numeral to an Arabic numeral. It is suggested you write this method first and test it. Let’s call it valueOf which, when given a String representing a Roman numeral will return an int for its integer Arabic value. That is, valueOf(“VII”) returns 7. A nice tutorial on Roman numerals and conversion to Arabic can be found at https://tutorialhorizon.com/algorithms/convert-roman-number-to-integer/
The link to this tutorial is also on Blackboard.
Submitting the Project.
You should now have the following files to submit for this project:
Project1.java
RomanANumeralGUI.java
(You do not have to submit TextFileInput.java or the input file.)
Submit a jar file.
Rather than upload the files above separately, we will use Java’s facility to create the equivalent of a zip file that is known as a Java ARchive file, or “jar” file.
Instructions on how to create a jar file using Eclipse are on Blackboard. Create a jar file called Project1.jar and submit that. When creating the jar file be sure to select the option to include source files (that is, .java files) and not .class files.
Upload your project to Blackboard by the due date for full credit.
