Project 08 Description For this lab you will write a Java program that manipulates numbers. The program will ask the user to enter a number (or a zero to quit) and then convert that number into a Roman numeral and display the result. The program will loop until the user enters a zero to end the program For this assignment you must start with the following "skeleton" of Java code. Import this into your Eclipse workspace and fill in the methods as directed. Feel free to add any methods you find useful, but make sure that you add comments indicating what they do following the form of the rest of the comments in the code.
