Question 3: (60 points) Student Management System In the following project, your task is to develop a "Student Management System" by applying the concept of a singly linked list. This system will help you efficiently organize and handle diverse student-related data. Within this system, each node will be equipped to carry relevant details for an individual student. These nodes will then be interconnected to construct an integrated singly linked list. Two pivotal components, specified as classes, make up the heart of this project: 1. Student Class holds the unique details of each student. Here's what it looks like: class Student { String id; String name; String course; int age; Student next; public Student (String id, String name, String course, int age) { } Within this class: Each student is designated with an 'id', 'name', 'course', and 'age'. The 'next' attribute points towards the next student in the linked list. this.id = id; this.name = name; this.course = course; this.age = age; this.next = null; 2. Student Management System Class, your control base, provides various functionalities for managing the student data: class Student Management System { Student head; public void addStudent (String id, String name, String course, int age) {...} public void displayStudents () {...} public void searchStudent (String id) {...} public void updateStudent (String id, String newName, String newCourse, int newAge) {...} public void delet public void countStudents () {...} } (String id) {...} Functions included in this class allow you to add students, display student information, search for a particular student by 'id', update student's details, delete a student's record, and count the total number of students. Each function utilizes various traversal methods and checks to ensure the proper function of the singly linked list. The given input text file for running this program consists of several command lines that instruct the application to perform certain operations like adding, displaying, searching, updating, deleting, and counting students. All students and operations are kept on individual lines. The commands must follow this format: 1. Add student: This command is followed by four parameters, separated by commas: 'ID', 'student name', 'course code', and 'student age'. For example: "Add student: ID1, Ahmed, CS101, 20" would add a new student with the ID 'ID1', the name 'Ahmed', taking the course 'CS101', and aged 20. IDs must be unique and should reflect the specific student's identifier. 2. Display students: Once this command is read, the application displays all students that are currently added. This is written as: "Display students: " 3. Search student: This command allows the application to locate a specific student by his/her ID. For instance, "Search student: ID1" would search for the student with the ID 'ID1'. 4. Update student: This command updates a student's data. Like the "Add student" command, it follows the format: "Update student: 'ID', 'new student name', 'new course name', 'new age"". Any part of a student's information can be updated this way. If the student's ID isn't found, no update will occur. 5. Delete student: This command removes a student from the system using their ID. Its format is "Delete student: "ID"". 6. Count students: This command outputs the total number of students currently in the application. This is written as "Count students: " in the input file. Remember to separate each command on a new line. Misformatted commands may cause errors or fail to function as expected. The UML class diagram for the project -head: Student Student Management System + addStudent (id: String, name: String, course: String, age: int) : void +displayStudents(): void + searchStudent (id: String): void + updateStudent (id: String, newName: String, newCourse: String, newAge: int): void + deleteStudent (id: String): void + count Students(): void Student Explanation of the UML: The Student class includes five private fields: id, name, course, age, and next. The constructor Student(id: String, name: String, course: String, age: int) initializes a new Student object. - id: String - name : String - course: String age: int -next: Student + Student (id: String, name: String, course: String, age: int) : void The Student Management System class includes head which is a Student object and several methods that perform various operations on the linked list of Student objects: addStudent(id, name, course, age) - append a new Student at the end of the linked list. displayStudents()) - print all student records. searchStudent(id) - find and print the student record for a given id, if it exists. updateStudent(id, newName, new Course, newAge) - update the student record for a given id, if it exists. deleteStudent (id) - delete the record for a given student id, if it exists. countStudents() - display total number of student records in the linked list. Please note that this UML only indicates types for method parameters and does indicate return types since all these methods don't return any value (they are all void).
