This is what the first few rows look like, I can't upload a file. It goes from 2010-11 to 2015-16, the file has 413,940 rows. Grades are A, B, C, D and F. The classes are all different.

Attached is a csv file that contains all of the grades for all of the students at Merced College from 2010-2016. Your task is to create a class to hold a record for this file. Then make a Test program to read in the data from the file into an Array of Objects. For your Grade object class make the following data variables and methods: .String year String course char grade . make 2 constructors; the default constructor and another constructor that take in 3 parameters to set your data variables make the setters, getters, toString, and equals methods. Make a test class that will read in the data from the following file into an array of Grade objects. You are then to make methods in your test class to answer 2 of the following questions What is the average grade in CPSC-39 for each of the years, for all of the students in that year? Just count the letter grades A, B, C, D, F What is the average number of students in a CPSC-39 class? Which computer Science Class has the highest amount of A's? (Computer Science classes have a course that contains the letters CPSC you can hard code the names of the classes in your code)
