Course Grade $($java$)$

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, Midterm$1$ score, Midterm$2$ 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 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:

A: $90=<$ x

B: $80=<$ x $<90$

C: $70=<$ x $<80$

D: $60=<$ x $<70$

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 Edan $704559$

Bradshaw Reagan $969788$

Charlton Caius $739480$

Mayo Tyrese $886136$

Stern Brenda $908645$

the file report.txt should contain:

Barrett Edan $704559$ F

Bradshaw Reagan $969788$ A

Charlton Caius $739480$ B

Mayo Tyrese $886136$ D

Stern Brenda $908645$ C

Averages: Midterm$183\mathrm{.}40,$ Midterm$276\mathrm{.}60,$ Final $61\mathrm{.}60$ Code: import java.util.Scanner;
