Complete and fully test the class Characteristic that Exercise 5 describes. Include the following methods:
• getDescription—returns the description of this characteristic. • getRating—returns the rating of this characteristic. • getCompatability(Characteristic otherRating)—returns the compatibility measure of two matching characteristics, or zero if the descriptions do not match. • getCompatibilityMeasure(Characteristic otherRating)—a private method that returns a compatibility measure as a double value using the formula .when both ratings are nonzero; m is zero if either rating is zero. (Recall from Exercise 5 that the constructor sets the rating to zero, indicating that it has not yet been determined.) • isMatch(Characteristic otherRating)—a private method that returns true if the descriptions match. This project is a continuation of Exercise 5. It adds methods that allow one to determine a numeric score for compatibility. Test cases are in the main method.
