Write a class Student that has these private fields:

String name

Integer ID

Double GPA

Integer N (Number of quizzes taken by this student) ? Array of N integers (grades of the quizzes)

And these public methods:

double quizzesAvg (which computes and returns the quizzes average grade) ? void print, which prints all the data of the Student.

void setGPA (to change the GPA to a new value)

A) Design a 4-parameter constructor (name, ID, GPA and quizzes array). Any trial to enter a negative quiz grade must generate the exception: negativeNotAllowed and the handler within the constructor must replace the negative grade with Zero.

The GPA must be in range [0..4]. If not, the constructor must throw the exception GpaRangeException to the caller. The test class (the caller) must handle this problem in any suitable way (Example: Skip that Student and generate a log text file of that error).
