Average and Grade Calculation

Develop a smart application as Student Grade Calculator(SGC).

Use class Student with following private attribute :

int id, String name, marks(integer array), float average and char grade. Include appropriate getters and setters methods and constructor.

publicvoid calculateAvg()- This method should calculate average and set average mark for the current student.

public void findGrade()- This method should set the grade based on the average calculated. If the average is between 80 and 100 then, then return grade as 'O', else 'A' .If the student gets less than 50 in any of the subjects then return grade as 'F'. Using appropriate setter method set the grade to the student.

(Note : number of subject should be greater than zero, if not display as 'Invalid number of subject' and get number of subject again, Assume mark for a subject should be in the range 0 - 100.If not display a message "Invalid Mark" and get the mark again)

Prepare class StudentMain and write the main method.

In this class, prepare method

public static Student getStudentDetails() - this method should get the input from the user for a student, prepare student object with those details and return that object.

In main create student's object by invoking the getStudentDetails method.Also calculate average and grade for that student object using appropriate methods.

SGC appshould get the input and display the output as specified in the snapshot:
