[Java HELP] Need help to complete rest of code

This assignment is built using the code from Assignment 5.

In this assignment create a separate serialized file using ObjectOutputStream for each student.

File should contain student's score and statistics for entire class.

Using debug mode (with Debug flag) print the contents of the serialized file.

Create and implement an interface to:

Print student statistics.

Print scores for a given student id.

implement the Debug flag globally

Use an abstract class to implement all the methods declared in an interface.
