Question

I need help with a java problem:

Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20. Assume also the last names and first names do not contain whitespaces. - (The rest in described in the attached image)

Code -

import java.util.Scanner;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.PrintWriter;
import java.io.IOException;

public class LabProgram {
public static void main(String[] args) throws IOException {
Scanner scnr = new Scanner(System.in);

/* TODO: Declare any necessary variables here. */


/* TODO: Read a file name from the user and read the tsv file here. */


/* TODO: Compute student grades and exam averages, then output results to a text file here. */

}
}

The program performs the following tasks:
. Read the file name of the tsv file from the user.
Open the tsv file and read the student information.
Compute the average exam score of each student.
Assign a letter grade to each student based on the average exam score in the following scale:
o A: 90 =< x
o B: 80 =< x < 90
o C: 70 =< x < 80
o D: 60 =< x < 70
o F: X < 60
Compute the average of each exam.
Output the last names, first names, exam scores, and letter grades of the students into a text file named report.txt. Output one
student per row and separate the values with a tab character.
Output the average of each exam, with two digits after the decimal point, at the end of report.txt. Hint: Use the precision sub-specifier
to format the output.
Ex: If the input of the program is:
●
StudentInfo.tsv
and the contents of StudentInfo.tsv are:
Barrett
Bradshaw
Charlton
Mayo
Stern
Edan
70 45 59
Reagan 96 97 88
Caius 73 94 80
Mayo
Stern
Tyrese 88 61 36
Brenda 90 86 45
the file report.txt should contain:
Barrett
Bradshaw
Charlton
70 45 59 F
Edan
Reagan 96 97 88 A
Caius 73 94 80 B
Tyrese 88 61 36 D
Brenda 90 86 45 с
Averages: Midterm1 83.40, Midterm2 76.60, Final 61.60
