Trying to make a working Program. Don't know how to build it. It should be easy

Tomorrow I have an exam that requires that I know how to read inputs from a text file and display results. I was given an assignment, that If I can solve it, will help me with tomorrows exam. I don't expect anyone to help me write this. But whoever does, Thanks a lot. It's not suppose to take long at all to write. I just can't get it figured out. The assignment is as follows:
Problem 1 part a: Create the following text file ("Week9.txt"), which states exactly as written:
78 George
90 John
97 Alex
80 Thomas
75 James
87 Andrew
55 Frank
82 Anna
91 Maria
74 Anton
92 Carolina

Problem 1 part b: Write a program that reads data from the file "Week9.txt" and displays:
The Person's name, his/her score and comment: "good job", if the score is at least 80, "work harder", if 60<=score<80, "see your teacher", if score<60.
The Person's name with highest score
The Person's name with lowest score
The average score


Additional Details

the programming language I'm using is Java, and I use JGrasp to run it.

Also this is the code I came up with


import java.io.*;
import java.util.*;

class ReadName
{
public static void main (String args []) throws IOException
{
String name;
int score;
Scanner inFile=new Scanner (new File ("Week9"));
while (inFile.hasNext();
}
inFile.close();
System.out.println();
}
public static findGrade (int n)
{
String a;
if (n>=80)
a="good job"
else if (n<80&&n>=60)
a="work harder";
else
a="see your teacher";
return a;
}
}
