JAVA PROGRAMMING: Feel free to correct my code (found below), or write your own to answer this question. Please comment if writing your own code or altering mine.

Write a program that asks the user to enter five test scores. The program should display a letter grade for each score, and test the average score. Write the following methods in the program:

CalcAverage--- This method should accept five test scores as arguments, and return the average of the scores

determineGrade--- This method should accept a test score as an argument, and return a letter grade for the score, based on the following scale

90-100 =A

80-89=B

70-79=C

60-69=D

Below 60=F
