PROBLEM You are given a file named "students.txt". Each row in the file contains a student's first name, last name, and their grades for 5 assignments. You will need to create an array called finalGrades. Set the size of this array to how many rows are in the file (not counting the header row). This array will store all the final grades for each student. For each row in the file (except the header row): 1) Store firstName and lastName as Strings, and then store the 5 grades into an array called grades. 2) Calculate the letter grade for each assignment (A >= 90, B >= 80, C >= 70, D >= 60. E >= 50). 3) Calculate the average grade of the 5 assignments. (Final grade) 4) Store the final grade into the finalGrades array 5) Write the students name, the letter grade of each assignment, and their final grade to a text file named "output.txt" At the end, write the lowest final score, highest final score, and the average final score to "output.txt". REQUIRED METHODS a) A method to calculate the average of a double array. b) A method to calculate the minimum of a double array. c) A method to calculate the maximum of a double array. d) A method to Calculate a letter grade for each assignment based on the grade percentage. e) A method to write a student's name, letter grade of each assignment, and their final grade to a text file. (This method should call method d and a) RUBRIC 15 points - All the required methods are declared, defined, and used properly. 15 points - Your output file is identical to the sample PDF provided 10 points - Your program compiles and runs without any errors. 10 points - All methods MUST use JavaDoc comments
