In a college first year class are having the following attributes Name of the
class (BCA, BCom, BSc), Name of the staff No of the students in the class, Array
of students in the class. Define a class called first year with above attributes
and define a suitable constructor. Also write a method called best Student ()
which process a first-year object and return the student with the highest total
mark. In the main method define a first-year object and find the best student
of this class*/
