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 IX 9
Write a main application called manchester.java(mainfile), 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.

MMXXIII,VII
Then the content pane of the GUI should contain
IX 9
MMXXIII 2023
VII 7
The core of this assessment 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
Note: input.txt is just a file with roman numerals
Given : Write a main application called manchester.java(mainfile)
