Write a class called Grades.
Grades are values between zero and 10 (both zero and 10 included), and
are always rounded to the nearest half point (i.e. ALL GRADES entered
in the system end in either .0 or .5). To translate grades to letters:
8.5 to 10.0 become an "A," 7.5 and 8.0 become a "B," 6.5 and 7.0
become a "C," 5.5 and 6.0 become a "D," and 0.0 to 5.0 become an
"F." Anything else is an error.
Implement a program such that, it asks the user for a grade, and then
it prints the corresponding letter. If the user enters a grade lower
than zero or higher than 10, print an error message (as in example
below). ALL GRADES MUST END IN EITHER .0 or .5, including 10.0 and
0.0.
examples:
(program must give the messages below)
% java Grades
enter a number grade: 8
Error: 8
% java Grades
enter a number grade: 8.0
letter grade is B
% java Grades
enter a number grade: 13.0
Error: 13.0
