In this assignment, you are to develop a java application that implements a university module registration system.
The module registration system allows the university administration staff to add and remove modules from the curriculum, register new student , remove student and register module to be taken by a student.
The system also provides the following display functions for administrator: 1. Display all the information for each module in the module list 2. Display the complete list of students 3. Display a list of modules currently taken by a particular student
The application:
A user in the Module Registration System is first presented with a main menu, the “Module Registration System Main Menu”. Two options will be presented, the “Module Matters” option and the “Student Matters” option. The “Module Matters” submenu will contain options pertaining to the administrative details of modules, whereas the “Student Matters” submenu will contain options pertaining to the administrative details of students.
Student Registration System 1. Add a student 2. Remove a student 3. Add a module 4. Remove a module 5. Display module list 6. Display student list 7. Register module(s) for a student 8. Display module(s) taken by a student 9. Quit
To implement such a system, your Java program should consist of the following supporting classes. 1. The Module class represents a module. A module has a moduleID (int), a moduleName (String), a population (int) property indicating the number of students currently taking it, and the classLimit (int), which is the maximum population size that can take the module, and a semester (int) property that indicates when the module is offered (either semester 1 or 2). The Module class has a constructor that takes in moduleID, moduleName, classLimit and semester. It has the following methods: /*Returns true when classLimit has been reached, not allowed to register a student for this module when class size is full */ public boolean isFull() /*Returns true when the module is offered in the semester sem */ public boolean isOfferedInSem(int sem) The toString method returns a String that contains all the property values in the form of <moduleID><moduleName><semester>> <Number of students taking it> <class limit> eg 101 Programming Fundamentals 1 100 130 202 Intermediate Programming 2 80 100 303 Advanced Programming 2 50 50
2. The Student class represents a student. A student has a studentID (int), a name (String),and a list of modules currently taking (ArrayList of Modules) It has a constructor that accepts studentID, and name.
3. The School class represents the Module Registration System in a school. It has three properties: the schoolName (String), and two collection lists, namely moduleList(ArrayList of modules) and studentList( ArrayList of students. The class has the following methods: addStudent – This method accepts a Student object and adds it to the studentList. addModule – This method accepts a Module object and adds it to the moduleList collection. removeStudent - This method accepts a int representing the studentID and searches for the student within the studentList collection. It returns true when the student is found, and removed from the studentList. Otherwise it returns false. removeModule - This method accepts a int representing the moduleID and searches for the module within the moduleList collection. It returns true when the module is found, and removed from the moduleList. Otherwise it returns false. searchStudent – This method accepts an int representing the studentID and searches for the student within the collection of students. It returns the student if found, otherwise it returns a null value. searchModule – This method accepts an int representing the moduleID and searches for the module within the collection of modules. It returns the module if found, otherwise it returns a null value. listModules – This method goes through the collection of the modules and displays all the information of each module in the moduleList. listStudents – This method goes through the collection of the students and displays all the information of each student in the studentList. classFull - accepts a moduleID (int) and checks if the classLimit for the module has been reached. isOfferedInSem - accepts a moduleID (int) and a sem (int). It checks if the module is offered in the semester sem. registerModule – This method accepts a studentID (int), a moduleID (int) and a semester (int). Returns true when the module is added to the module list in the Student object. Otherwise it returns false.
ListModulesTaken – This method accepts a studentID (int) and display a list of modules taken by the student in the format shown below. 005 Tan Ah Teck 101 Programming Fundamentals 202 Intermediate Programming
4. The SchoolApp class is the driver class, It should create an instance of the School class with Bogus School as the school name, followed by displaying the main menu option. Based on this option, a relevant submenu is then displayed. The choice made on the submenus will determine the nature of task. This task is performed using appropriate methods of the School, Module and Student classes. To perform the task selected, the driver class should include the following functionalities: Add a student Prompts user for the relevant input to create a new student object, It should check if there is any duplicate before the student is created, If there is no duplicate, the new student object is created and added into studentList within the School class using the addStudent method. The option should display either “Duplicate student ID” if the student ID already exists, or “Added 002 Tan Ah Teck successfully” if the add is successful.” 002 is the studentID, whereas Tan Ah Teck is the student name. Remove a student Prompts the user for a student ID. For simplicity no check is required to remove the student. The option should display either “Non-existing <studentID> – removed failed”, or “Removed <studentID> successfully”
Add a module Prompts the user for the relevant input to create a Module object. It should check if there is any duplicate before the object is created. If there is no duplicate, the Module object is created and added into the collection of the ModuleList (ArrayList) within the School class using the addModule method. The option should display either “Duplicate module ID” if the module ID already exists, or “Added 101 Programming Fundamentals successfully” if the add is successful.”. This option keeps prompting about semester when the semester input is invalid. Remove a module Prompts the user for a moduleID. Allows the user to remove the module only when no students are currently taking the module, The option should display either “Non-existing <moduleID> – removed failed”, or “There are still students taking the module – removed failed”, or “Removed <moduleID> successfully” Display module list It searches through the collection of modules and displays all information about the module. This option should display either “Module list is empty” if there is no module listed yet, or in the format <ModuleID> <moduleName><semester><population><classLimit> , eg 101 Programming Fundamentals 1 100 130 202 Intermediate Programming 2 80 100 303 Advanced Programming 2 50 50 Display student list Go through the studentList and displays the studentID and name for each student. This option should display either “Student list is empty” if there is no student listed yet, or in the format <studentID><studentName>, eg: 001 Tan Daisy 002 Tan Ah Teck Display modules taken by a particular student This method accepts a studentID (int) and display a list of modules taken by the student in the format shown below. 001 123 Module1 Name 234 Module2 Name Where 001 is the studentID, 123 and 234 are the module ids,Module1 Name and Module2 Name are the respective module names Register Module for a student This option allows administrator to register student to take a particular module. The user specifies the studentID, moduleID and semester. It checks whether the module has currently being registered . On top of this, it verifies that the class limit for that module has not been reached and the module is offered in the semester. Given all the verification is successful, the module is added to the collection of modules in Student class. A successful registration will produce a format similar to the following output “Student 002 registered for module 202 in semester 1 successfully“ If the studentID or moduleID is not found, the following output is produced: “Registration failed – invalid studentID or moduleID” Lastly, if the registration is unsuccessful as the module is not offered in this semester, it produces the output “Registration failed as module is not offered in semester <semester>” <semester> is the integer input keyed in by the user earlier. For successful registration, remember to increment the population property of Module object.
