Question
Write a java program called Grade to calculate the current grade based on this grading system:
Exams =45%
Project=20%
Assignments=20%
Final Exam=15%
Additionally, attendance will be reflected in the final grade.
Final grades will be determined as follows:
93-100=A 80-82=B- 67-69= D+
90-92=A- 77-79= C+ 63-66= D
87-89=B+ 73-76=C 60- 62=D-
83-86=B 70-72= C- 00- 59 =F
the program should prompt the user for their first name and last name. It will then pass those names as Strings to the second method of the Grade class. The name of the second method will be calcGrade. This method will prompt the user for the count of exam scores, count of quiz scores, and count of lab scores to enter by the user.
it will the utilize repitition structure to prompt for exam grades, quiz grades and lab grades based on the previous counts entered. For example, if the user entered count of exam scores to be 2; then the program will loop 2 times to input the two exam grades; and similarly for count for quiz and count lab grades.
Assume you have a 100% attendance record and you will get all 5% of the attendance grade.
Assume all exams,labs,quiz scores are out of 100 points.
Example program run:
First name: James
Last name: Bond
How many exam grades do you have? 1
How many quiz grades do you have? 2
How many lab grades do you have? 2
Enter exam 1 score: 90
Enter quiz 1 score: 80
Enter quiz 2 score: 80
Enter lab 1 score: 90
Enter lab 2 score: 90
Total Score: 84.55
James Bond your grade is a: B
The program will need to include comments for each block of code, and addittional methods outside of the main() method, such as public static void calcGrade(String first, String last)
