Interface

Assignment: You are given the following interface:

interface Stats {
double getAverage(); //returns the average of scores in grades.txt
int getHighest(); //returns the highest score in grades.txt
int getLowest(); //returns the lowest score in grades.txt
}

implement the interface in a class called Grades. The program will read a series of integers (one per line) from a file called grades.txt and then output to the screen the result of calling each of the methods listed in the interface above.
