Java:

complete and fully test the class Characteristic that excercise 5 descirbes.

Excercise 5:

- description - a string thay identifies the characteristic

- rating - an integer between 1 and 10 that identifies a person's desire for this characteristic in another person.

a. write a constructor that sets the description of the characteristic to a given string and sets the rating to zero to indicate that it has not yet been determined.

b. Write a private method isValid(aRating) that returns true if the given rating is valid, that is, is between 1 and 10.

c. Write a method setRating (aRating ) that sets the rating to aRating if it is valid.

d. Write a method setRating that reads a rating from the keyboard insisiting that the rating supplied by the user be valid.

Include the following methods:

- getDescription - returns the description of this characteristic.

- getRating - returns the rating of this characteristic.

- getCompatability(Characteristic otherRating) - returns the compatability measure of two matching characteristics, or zero if the descriptions do not match.

- getCompatabilityMeasure(Characteristic otherRating) - a private method that returns a compatability measure as a double value using the formula:

[ m = 1- ((r1-r2)^2) / (81)]

when both ratings are nonzero; m is zero if either rating is zero. (Recall from excercise 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.
