Math class and its different methods

Java math class consists of arithmetic math methods that performs basic numeric operations such as finding the maximum or minimum of two values, rounding values, logarithmic functions, square root, and trigonometric functions, etc. The Math library functions can be accessed using the header Java.lang.Math. These math methods under Java math class are for our convenience.

Question

Q2.
Create a complete program that uses the getNumsFromUser() method in Q1 to
read in student marks (double) from the user, determines the highest mark, then ranks
students based on how their mark compares to the highest mark, and displays their mark
and letter grade. Use the following system of subtracting the student's mark from the highest
mark to determine their letter grade.
Mark
mark > best - 10
mark > best - 20
mark 2 best 30
mark 2 best - 40
otherwise
Grade
A
В
You MAY write all your code for this question, along with the call for getNumsFromUser( ),
inside the main method. However, if you choose to write a method for this code and call it in the
main method, you may use this header:
public static void showLetterGrades (double[] grades)

Sample run
Enter number of students: 4
Enter student grades: 67 93 55 78
Student 1 score is 670 and grade is C
Student 2 score is 93.0 and grade is A
Student 3 score is 55.0 and grade is D
Student 4 score is 78.0 and grade is B
