BJP4 Exercise 4.15: getGrade

Language/Type: Java if/else method basics
Author: Will Beebe (on 2016/09/08)

Write a method called getGrade that accepts an integer representing a student's grade in a course and returns that student's numerical course grade. The grade can be between 0.0 (failing) and 4.0 (perfect). Assume that scores are in the range of 0 to 100 and that grades are based on the following scale:

Score Grade
<60 0.0
60-62 0.7
63 0.8
64 0.9
65 1.0
92 3.7
93 3.8
94 3.9
>=95 4.0

For an added challenge, make your method throw an IllegalArgumentException if the user passes a grade lower than 0 or higher than 100.
