1. Create an application called Registrar that has the following classes;A Student class that minimally stores the following data?elds for a student;? name;? student id number;? number of credits;? total grade points earned;The following methods should also be provided;? A constructor that initializes the name and id?elds;? A method that returns the student name?eld;? A method that returns the student ID?eld;? A method that determines if two student objects are equal if their student;id numbers are the same (override equals from the class Obj ect);? Methods to set and retrieve the total number of credits;? Methods to set and retrieve the total number of grade points earned;? A method that returns the GPA (grade points divided by credits);An Instructor class that minimally stores the following data?elds for an instructor;? name;? faculty id number;? department;The following methods should also be provided;? A constructor that initializes the name and id?elds;? Methods to set and retrieve the instructor?s department;A Course class that minimally stores the following data for a course;? name of the course;? course registration code;? maximum number of 35 students;? instructor;? number of students;? students registered in the course (an array);The following methods should also be provided;? A constructor that initializes the name, registration code, and maximum;number of students;? Methods to set and retrieve the instructor;? A method to search for a student in the course, the search should be;based on an ID number.;? A method to add a student to the course. If the course is full, then an;exception with an appropriate message should be raised (try creating your;own exception class for this). Also, be sure that the student is not already;registered in the course. The list of students should be in the order that;they registered.;? A method to remove a student from the course. If the student is not;found, then an exception with an appropriate message should be raised;(use the same exception class mentioned above).;? A method that will allow Course objects to be output to a?le using;object serialization;? A method that will allow Course objects to be read in from a?le created;with Object serializtion;You will note that the Student and Instructor classes described above have;some commonality. Create a Person class that captures this commonality and uses;it as a base class for Student and Instructor. This class should be responsible for;the name and id?elds and also provide a toString method that returns a string of;the form name, id. This will be the inherited toString method for the Student;and Instructor classes.;a. Draw a UML diagram for this application.;b. Implement the previous classes in Java. Write a main program that can serve as a test;class that tests all of the methods created and demonstrates that they are working.;c. Write a second main program that provides a menu to allow the user to;i. create a course, prompting the user for all of the course information;ii. add students to the course;iii. check to see if a student is registered in the course, and;iv. remove a student from the course.;d. Add to the previous menu the ability to save a course using object serialization.;Also add a menu choice to read in a course from a file given the course code.;Come up with a system of naming the file so that the user need only be asked;the course code to load the course information from a file.
