Question

Create a class named student. a student has fields for an id number, number of credit hours earned, and number of points earned. (for example, many schools compute grade point averages based on a scale of 4, so a three-credit-hour class in which a student earns an a is worth 12 points.) include methods to assign values to all fields. a student also has a field for grade point average. include a method to compute the grade point average field by dividing points by credit hours earned. write methods to display the values in each student field. save this class as student.java.
