Answer 1

Вы должны добавить дочерний субъект в конструктор TeacherInfo , как и другой объект.

    public TeacherInfo(String name, String department, String phone, String email, String password, ArrayList<String> subjects) { 
        this.name = name; 
        this.department = department; 
        this.phone = phone; 
        this.email = email; 
        this.password = password; 
        this.subjects = subjects;
    }

Или вам нужно реализовать Geter: Seter для дочерней сущности.
