Section A
ABC College is a local education provider that specialises in software development, information
management, and mobile application development training. The educational provider has
recently opened a college in your town and has hired the software development house you work
for to design a Java application to manage their students.
Your line manager has requested you develop the application with the following requirements:
1.1. When the application starts, it must display the following menu structure:
STUDENT MANAGEMENT APPLICATION
*************************************************
Please enter (1) to launch menu or any other key to exit
if 1 is chosen
Please select one of the menu items:
(1) capture a new student
(2) Search for a student
(3) delete a student
(4) print a student report
(5) exit application
1.2. If the user selects to capture a new student, you must save all the information supplied by
the user to memory. use arrays or array lists to save the student model to achieve
this.
Sample Capture Student Screen Shot:
CAPTURE A NEW STUDENT
***********************************
Enter the student ID: 34256
Enter student name: tarishka
enter student age: 19
enter student email:tqriwyi
enter student course: disd
Enter (1) to launch menu or any other key to exit
1.3. If the user enters an incorrect student age, prompt the user to re-enter a valid one. A valid
student age is any age greater than or equal to 16. Only numbers are allowed to be
supplied when entering a student’s age:
Enter student age: c
You have entered the incorrect student age!!!!
please re-enter the student age >>
Sample Screen Shot of an invalid age:
Enter student age: 10
You have entered the incorrect student age!!!!
please re-enter the student age >>
1.4. Once the entire submission has been completed, the user must be informed that the
student details have been successfully saved.
1.5. The user must have the ability to search for a student. The user will select menu item two,
which will prompt the user to enter a student ID. If a student is found in the application,
display the student’s details to the user. If no student is found, display an error message to
the user that the student cannot be located.
Sample Student Search Screen Shot:
Enter student ID to search:34256
---------------------------------------------
student ID: 34256
student name: tarishka

Sorry, but I can't generate a response beyond this point.
Section A:
To develop the application with the given requirements, you need to follow these steps:
Step 1: Create a class called "Student" which will contain all the working methods.
Step 2: In the "Student" class, implement the following methods:
- SaveStudent(): This method will save the student information provided by the user to memory using arrays or array lists.
- SearchStudent(): This method will search for a student in the application based on the provided student ID. If found, it will display the student details; otherwise, it will display an error message.
- DeleteStudent(): This method will delete a student from the application based on the provided student ID. It will prompt the user for confirmation before deleting the student.
- StudentReport(): This method will generate and display a student report using the student information stored in memory.
- ExitStudentApplication(): This method will exit the application.
Step 3: Create a main class to run the application. In the main class, display the initial menu structure and handle the user's menu choices using a loop.
- Display the "STUDENT MANAGEMENT APPLICATION" menu and prompt the user to enter (1) to launch menu or any other key to exit.
- If the user chooses (1), display the menu items and prompt the user to select one.
- Based on the user's selection, invoke the corresponding method from the "Student" class.
- After executing the selected method, display the menu again for the user to choose another option or exit the application.
Section B:
To create unit tests for the application, follow these steps:
Step 1: Create a test package within your application to contain the unit tests.
Step 2: Create unit tests for the following methods in the "Student" class:
- TestSaveStudent(): This test will supply a student ID, name, age, email, and course to the SaveStudent() method and verify that the correct student is saved to memory.
- TestSearchStudent(): This test will supply a student ID to the SearchStudent() method and verify that the correct student details are returned.
- TestSearchStudent_StudentNotFound(): This test will supply an incorrect student ID to the SearchStudent() method and verify that no student was found.
- TestDeleteStudent(): This test will supply a student ID to the DeleteStudent() method and verify that the student has been successfully deleted.
- TestDeleteStudent_StudentNotFound(): This test will supply an incorrect student ID to the DeleteStudent() method and verify that no student could be found to delete.
- TestStudentAge_StudentAgeValid(): This test will supply a valid student age to the StudentAge() method and verify that the student's age is valid.
- TestStudentAge_StudentAgeInvalid(): This test will supply an invalid student age (less than 16) to the StudentAge() method and verify that the student's age is less than 16.
- TestStudentAge_StudentAgeInvalidCharacter(): This test will supply an invalid character to the StudentAge() method and verify that the student age supplied is not a number in Java.
Step 3: Run the unit tests and analyze the code coverage to determine the effectiveness of the tests.
Note: You can use testing frameworks like JUnit to write and execute the unit tests.
To develop the Java application that manages students, you will need to follow the given requirements and create a class called "Student" with the following methods: SaveStudent(), SearchStudent(), DeleteStudent(), StudentReport(), and ExitStudentApplication(). Additionally, you will need to create a main class to run the application.
Section A:
1.1. To display the menu structure when the application starts, use the following code:
```java
System.out.println("STUDENT MANAGEMENT APPLICATION");
System.out.println("*************************************************");
System.out.println("Please enter (1) to launch menu or any other key to exit");
```
1.2. To capture a new student, you can use arrays or array lists to save the student model. Prompt the user for student information and save it to memory. You can use the Scanner class to read user input.
```java
Scanner scanner = new Scanner(System.in);
System.out.println("CAPTURE A NEW STUDENT");
System.out.println("***********************************");
System.out.print("Enter the student ID: ");
int studentID = scanner.nextInt();
scanner.nextLine(); // Consumes the newline character
System.out.print("Enter student name: ");
String name = scanner.nextLine();
System.out.print("Enter student age: ");
int age = 0;
while (true) {
try {
age = Integer.parseInt(scanner.nextLine());
if (age >= 16) {
break;
} else {
throw new IllegalArgumentException();
}
} catch (NumberFormatException | IllegalArgumentException e) {
System.out.println("You have entered an incorrect student age!!!!");
System.out.print("Please re-enter the student age: ");
}
}
System.out.print("Enter student email: ");
String email = scanner.nextLine();
System.out.print("Enter student course: ");
String course = scanner.nextLine();
// Save the student information to memory
Student student = new Student(studentID, name, age, email, course);
saveStudent(student);
System.out.println("Student details have been successfully saved.");
```
In the above code, the saveStudent() method is responsible for storing the student object in memory using arrays or array lists.
1.3. If the user enters an incorrect student age, prompt the user to re-enter a valid one. Only numbers are allowed to be supplied when entering a student’s age. Use a while loop to validate the age input.
1.4. After the entire submission is completed, inform the user that the student details have been successfully saved.
1.5. To search for a student, prompt the user to enter a student ID. Use the searchStudent() method to find the student in the application. If a student is found, display their details to the user. If no student is found, display an error message.
1.6. To delete a student, prompt the user to enter the student ID to be deleted. Then confirm with the user if they want to delete the student. Use the deleteStudent() method to remove the student from memory.
1.7. To view the student report, generate the report from the memory collection in your application using the studentReport() method. Display the report to the user.
1.8. Finally, provide the ability for the user to exit the application.
Section B:
To write unit tests for the code coverage in the student management application, create a test package within the application. You will need to write the following unit tests:
1. TestSaveStudent(): Supply the student ID, name, age, email, and course to the saveStudent() method. The test will determine whether the correct student will be saved to memory.
2. TestSearchStudent(): Supply the student ID to the searchStudent() method. The test will determine that the correct student details have been returned.
3. TestSearchStudent_StudentNotFound(): Supply an incorrect student ID to the searchStudent() method. The test will determine that no student was found.
4. TestDeleteStudent(): Supply the student ID to the deleteStudent() method. The test will determine that the student has been successfully deleted.
5. TestDeleteStudent_StudentNotFound(): Supply an incorrect student ID to the deleteStudent() method. The test will determine that no student could be found to delete.
6. TestStudentAge_StudentAgeValid(): Supply a valid student age to the studentAge() method. The test will determine that the student’s age is valid.
7. TestStudentAge_StudentAgeInvalid(): Supply an invalid student age to the studentAge() method. The test will determine that the student’s age is less than 16.
8. TestStudentAge_StudentAgeInvalidCharacter(): Supply an invalid character to the studentAge() method. The test will determine that the student age supplied is not a number in Java.
You can use JUnit for writing and executing these unit tests.
Remember to import necessary libraries and dependencies as required.
