Define a new class Student EnrolmentSystem in a new source file Student Enrolment System.java that contains private data members: students: is a list of Student objects; subjects: is a list of Subject objects; enrolments: is a list of Enrolment objects. Implement Java methods in the file Student Enrolment System.java that include: Initialization constructor that creates empty lists for all data members; Use the students' information provided above to add the objects of students to the correct list; Use the subjects' information provided above to add the objects of subjects to the correct list; Display a menu that includes 8 items below: 1. Display all students 2. Display all subjects 3. Display all enrolments 4. Find a student 5. Find a subject 6. Find a student's enrolments 7. Add an enrolment 8. Exit The Java program gets an input number of the menu, processes the required method for that item until 8 is input. When item 1 is selected, all the students' information is displayed. When item 2 is selected, all the subjects' information is displayed. When item 3 is selected, all the enrolments' information is displayed. When item 4 is selected, a user inputs a student number. Then the method finds the student record according to the student number and displays the student's information. If the student does not exist, display messages such as The student does not exist. When item 5 is selected, a user inputs a subject code. Then the method finds the subject record according to the subject code and displays the subject's information. If the subject does not exist, display messages such as The subject does not exist. When item 6 is selected, a user inputs a student number. Then the method finds and displays all the enrolments' information for the student. If no enrolment found for the student, display messages such as The student hasn't enrolled in a subject. When item 7 is selected, a user inputs a student number. If the student exists, then the user inputs a subject code. If the subject exists, then check if the student has already enrolled in the subject or not. If the student hasn't enrolled in the subject, a new enrolment object is added to the enrolment list. Otherwise, the method displays messages such as The student has enrolled in the subject already. The whole UML activity diagram of the system is given below.
