Write a Java program that calculates the grades of students in a given course.

The program will prompt the instructor to enter the names of students, their ID, attendance, assignments, halfterm and final.

It will then calculate the total and the letter grade as follows:

Total: Attendance: 10%

Assignments: 20%

Midterm: 30%

Final: 40%

Letter grade:

A: total 90

B: 80 total < 90

C: 70 total < 80

D: 60 total < 70

F: total < 60

Finally, the program will display students information and their corresponding grades. You must use appropriate array(s) to keep the data during execution.
