In Java lang please.
1. Create a read / write interface:
Public methods:
Reading from a file-public void read_File();
Save or change to a file-public void write_File(String File);
2. To create a Student class CStudent, implements
Comparable
Hidden member variables:
Name - String;
List of grades Integer - List ;
Faculty number - String;
Public methods:
2.1 Constructors - default, explicit (name, faculty number);
2.2 Reading a name (get);
2.3 To obtain an average score getGrade ();
2.4 Add rating addScore (int score);
2.5 String interpretation;
2.6 Implement Comparable; ;
3. To create a class CCourse designed to store 1-class objects,
implements Comparable and read / write interface
Hidden member variables:
Course name - String;
List of students;

Public methods:
3.1 Constructors - explicit (name of the course); explicit (file
name-String Filename) - see file format;
3.2 implement interface read / write ;
3.3 Reading a course name (get);
3.4 Rating function: addScore (String faculty number, grade
list);
3.5 Adding a group of grades to a student: addScores (String
faculty number, grade list);
3.6 Outputting course results: displayScores () displays an
example output (see bottom);
3.7 Adding a student with name and faculty number to the course:
makeStudent (String faculty number, String name);
3.8 Implement Comparable;
4. Main function:
4.1 Creating several 2-class objects. Output of the objects on the
console output and check of the functions of 2-class;
4.2 Exception handling;
Output:
GROUP1
19620001 STUDENT1 6 5 4 3 5: 4.60
19620002 STUDENT2 5 5 4 4 5: 4.60
19620003 STUDENT3 6 5 5 4 5: 5.00
