The purpose of this project is to use the basic java skills to create a simple grading system by building structured program. To build JANA GRADING SYSTEM you have to follow the following instructions.

In the main method you should do the following:
A. Declare and initialize an array to store the course name or code.
B. Declare and initialize an array to read the courses marks from the user.
C. Based on the marks entered by user in each course convert them to grades based on the following rules.
If the mark is >100 the Grade is ‘Error'
If the mark is > 90 the Grade is ‘A'
If the mark is > 80 the Grade is ‘B'
If the mark is > 70 the Grade is ‘C'
If the mark is > 60 the Grade is ‘D'
If the mark is < 60 the Grade is ‘F'
D. Print the courses name / code, the marks and the grades for the student in a good format.
E. Compute and print the average marks of the student on his / her several courses.
F. Call the CGPA_calculation method and print the CGPA.
G. Call the Smallest_mark method and print the lowest mark.
H. Call the Largest_mark method and print the highest mark.
I. Repeat the previous procedure if you still have more students.
You have to define the following three methods:
Write the following three user-defined methods that received an array as parameter:

A.CGPA_calculation: A method that takes an array of students marks as a parameter to calculate and return the CGPA according to the following formula:

∑ (No. of Credits x Grade Point)/∑ No. of Credits

B. Smallest_mark: A method that takes an array of students marks as a parameter and returns the lowest mark.
C. Largest_mark : A method that takes an array of students marks as a parameter and returns the highest mark.

Project presentation

Each student should present his/her work in front of his/her classmates. The evaluation of your presentation will be based on the following criteria: - Accuracy of the presentation -Presentation skills -Quality of discussion
