Assignment:  Write a RomanNumeral class.


Total point value of assignment:  100 points
Not accepted late.

This assignment is to be done INDIVIDUALLY.

Assignment:  Design and implement a class, RomanNumeral, which must be stored in
     a file named RomanNumeral.java.  (20 point deduction for failure to name
     file correctly!)  RomanNumeral.java must contain at least the following:


      public class RomanNumeral
      {
         // instance variable(s)

         // constructors
         public RomanNumeral ( int number )

         public RomanNumeral ( String numeral )

         // methods
         public String toString ( )
         // post:  returns a String representation of the Roman numeral
        

         public boolean equals ( String otherNumeral )

         public boolean equals ( int otherNumeral )

         public void inc ( )
         // post:  1 has been added to value of this RomanNumeral

         public void dec ( )
         // post:  1 had been subtracted from value of this RomanNumeral

         public static void main ( String [ ] args )
         // test driver for RomanNumeral class
      {

     You may include any additional methods you need, such as the method you
     wrote for Assignment #2.  Such methods must be declared private instead
     of public.

     Your initial decision is how to store the value of the Roman numeral
     in an instance variable.  Obvious possibilities are to store it as
     an integer or to store it as a String.  DO NOT STORE IT AS BOTH.
     CHOOSE ONE REPRESENTATION ONLY.  The problem with using more than
     one representation for the same data is integrity.  If you were to use
     two (or more) representations for the same information, then every time
     one representation was changed the other must be changed also. 

Grading Rubric:

	10 pts. reasonable attempt to solve problem as assigned --
            includes storing only one representation of numeral value
	10 pts. also compiles
	10 pts. style standards (includes clarity)

    The following 70 points are available only for code that compiles 
    without error.  We will use our test driver.. 

    15 pts. constructors 
    15 pts. equals methods 
    15 pts. inc and dec 
     5 pts. toString 
	15 pts. correctness of implementation        
	        (both correctness of individual methods and interaction of methods)
     5 pts. elegance of algorithms used in solution
