***I need help with what code to put in FirstName_LastName class and the MyCourse class***  [1] Description: You’re asked to create a basic Student’s Enrollment System with the provided Student and Course classes. Please download the source code files from Blackboard. Create two new classes: (i) FirstName_LastName (replace by your name) that extends the Student class and (ii) MyCourse that extends the Course class. [2] Requirements: a. You’re NOT allowed to change or add ANYTHING in the provided Student and Course classes. b. Provide a no-arg constructor for your FirstName_LastName class. The no-arg constructor should initialize all the data fields in Student class based on your information and your current semester’s enrolled courses. c. Override 6 methods in Student class, as marked in the source code comments. Please read the comment sections carefully for descriptions. d. Override the equals() method in MyCourse class. Two courses are equal if they have the same course number, course name, and credit hours. You should use this method for all courses comparisons. e. Create a customized exception class CourseNotFoundException, throw this exception in the dropCourse() method if the dropping course doesn’t exist in the courseList. The thrown exception object should contain a meaningful message, including course number, course name, and credit hours for the not found course. class Course {     private String courseNumber;     private String courseName;     private int creditHrs;     public Course (String number, String name, int creditHrs){         this.courseNumber = number;         this.courseName = name;         this.creditHrs = creditHrs;     }     public String getNumber() {         return courseNumber;     }     public String getName() {         return courseName;     }     public int getCreditHrs() {         return creditHrs;     }     public void setCourseNumber(String courseNumber) {         this.courseNumber = courseNumber;     }     public void setCourseName(String courseName) {         this.courseName = courseName;     }     public void setCreditHrs(int creditHrs) {         this.creditHrs = creditHrs;     } } class Student {     private String firstName;     private String lastName;     private String gender;     private String phoneNumber;     private String email;     private String jNumber;     protected ArrayList courseList;     public String getFullName() {         return firstName + " " + lastName;     }     public void setFirstName(String fName) {         firstName = fName;     }     public void setLastName(String lName) {         lastName = lName;     }     public String getGender() {         return gender;     }     public void setGender(String gen) {         gender = gen;     }     public String getPhoneNumber() {         return phoneNumber;     }     public void setPhoneNumber(String pNumber) {         phoneNumber = pNumber;     }     public String getEmail() {         return email;     }     public void setEmail(String e_mail) {         email = e_mail;     }     public String getJNumber() {         return jNumber;     }     public void setJNumber(String jNum) {         jNumber = jNum;     }     /* OVERRIDE!     Print student's basic information following the format in the assignment's description*/     public void printBasicInfo() {     }     /* OVERRIDE!     Print all courses following the format in the assignment's description */     public void printCourseList() {     }     /* OVERRIDE!     Enroll a new course by adding it into the courseList     Do NOT add a course if it is already in the courseList */     public void addCourse(MyCourse course) {     }     /* OVERRIDE!     If the course exists, remove it from the courseList         throw CourseNotFoundException if it doesn't exist*/     public void dropCourse(MyCourse course) {     }     /* OVERRIDE!     Return true if the course is currently enrolled, otherwise, false */     public boolean isEnrolled(MyCourse course) {         return false;     }     /* OVERRIDE!     Return total credit hours for all enrolled courses */     public int getTotalCredits() {         return 0;     } }
