![When submitting this lab, submit a java file called Student TestScores, and create the following structure in
Eclipse:
Some problems require data from a file be loaded into memory but processed later. To simulate this
scenario, write a program that uses the Scanner to open a file and read each line, storing the data into a
multi-dimensional array. In this assignment, you will read in all the data from the Student Test Grades.csv
file and store it in a multi-dimensional array. Then you will display the data to the console in the form of
letter grades as shown in the example run.
Package Name: week 10
o Class Name: Student TestScores
• Create an ArrayList of String arrays:
ArrayList<String[]> class Roster = new ArrayList<String[]>();
• Read each row of the "Student Test Grades.csv" file into your program as Strings
.
using while(file.hasNext())
Convert each read-in String to a String[] array using the String.split(",") method
•
• Add the String[] array to the classRoster ArrayList
•
When you have finished loading all the data into the ArrayList, close the file.
Now it's time to loop through the classRoster ArrayList and display the data while converting the numeric
scores into letter grades.

.
Loop through all the elements of the class Roster ArrayList
To help with readability, temporarily store each element in the classRoster ArrayList in a
variable you can easily access.
Example:
for(int i = 0; i < classRoster.size(); i++)
String[] student = classRoster.get(i)
Remember: The first element in the classRoster ArrayList is not a student. It is the header for
the table and should be displayed differently as shown in the example run.
Loop through each element of the student String[] array and convert the numeric value into a
letter grade as shown in the table below.
Remember: The first element in the student String[] array is the student's name and should be
printed before you start the for loop to process the grades.
The following table breaks down test score percentages to letter grades:](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb9fd5ae7-d259-446a-8ec7-3c4670a7f62b%2F4571d819-714a-42ce-ac9a-b92af752eccc%2F5qn0t1g_processed.jpeg&w=3840&q=75)

For this lab you will need to download the file Student Test Grades.csv Download Student Test Grades.csv.
This file contains a list of students and the scores they received for 3 tests. Place this file in your PROJECT
directory. Assume that your folder structure is similar to below.
eclipse-workspace -> CS105 -> src-> week 10 ->StudentTestScores
Then you would place the "Student Test Grades.csv" file in your CS105 directory
eclipse-workspace -> CS105
The format of the file looks like this:
Student, Test 1, Test 2, Test 3
Walter Koenig, 67, 88, 78
William.....
> 80%
> 77%
> 74%
> 70%
> 67%
>64%
> 60%
