Write a Java program that translates a number into the closest letter grade. For example, the number 2.8 (which might have been the average of several grades) would be converted to B-. Break ties in favor of the better grade; for example, 2.85 should be a B. Any value >= 4.15 should be an A+. Write a class Grade with a method
Write a Java program that translates a letter grade into a number grade. Letter grades are A B C D F, possibly followed by + or -. Their numeric values are 4, 3, 2, 1, and 0. There is no F+ or F-. A + increases the numeric value by 0.3, a - decreases it by 0.3. However, an A+ has the value 4.0. All other inputs have value -1.
