General Guidelines When Writing Programs:

$-$ Include the following comments at the top of your source codes

$//-----------------------------------------------------$

$//$ Miniproject$2($include number$)$

$//$ Question: $($include question$/$part number, if applicable$)$

$//$ Written by: $($include your name and student ID$)$

$//-----------------------------------------------------$

$-$ In a comment, give a general explanation of what your program does. As the programming

questions get more complex, the explanations will get lengthier.

$-$ Include comments in your program describing the main steps in your program.

$-$ Display a welcome message which includes your name.

$-$ Display clear prompts for users when you are expecting the user to enter data from the keyboard,

and all output should be displayed with clear messages and in an easy to read format.

$-$ End your program with a closing message so that the user knows that the program has terminated.

File Management System Implementation

You are tasked with implementing a simple file management system in Java. The

system should involve the use of inheritance and polymorphism to represent different

types of files and directories.

Requirements

$1.$ Create a base class called FileSystemElement with the following attributes:

$$ name $($String$)$

$$ size $($int$)$

$$ createdDate $($String$)$

$2.$ Create two derived classes called File and Directory that inherit from

FileSystemElement.

$3.$ The File class should have an additional attribute: extension $($String$).$

$4.$ The Directory class should have an additional attribute: contents $($ArrayList of

FileSystemElement$).$

$5.$ Each derived class should have a constructor that initializes all of its attributes.

$6.$ Implement a method called displayDetails in the FileSystemElement class that

prints out the details of the element $($name$,$ size, and created date$).$

$7.$ Implement a method called displayDetails in each derived class that overrides the

method in the base class and adds additional details $($e$.$g$.,$ extension for files, list

of contents for directories$).$

$8.$ Create a method in the Directory class called addFile that simulates adding a file

to the directory.

$9.$ Test your classes by creating instances of File and Directory, setting their

attributes, and displaying their details.

Instructions

$1.$ Create a new Java project and create the FileSystemElement, File, and Directory

classes as described above.

$2.$ Implement the displayDetails method in each class.

$3.$ Implement the addFile method in the Directory class.

$4.$ Test your classes by creating instances of each class and displaying their details.

$5.$ Submit your Java code and report as a single ZIP file following the submission

guidelines provided.

Submission Guidelines of miniproject$2$

$1.$ Submit your Java code and report as a single ZIP file named according to the

provided format.

$2.$ Submit your ZIP file to the designated submission area on the course platform.

$3.$ Include clear instructions on how to compile and run your code.

$4.$ Ensure your code is well$-$documented and organized.

Evaluation

Your miniproject$2$ will be evaluated based on the following criteria:

$1.$ Correctness of the Java code.

$2.$ Implementation of the displayDetails method in each class.

$3.$ Implementation of the addFile method in the Directory class.

$4.$ Testing of the classes with appropriate creation of instances and display of details.

$5.$ Adherence to good coding practices, including commenting, indentation, and

proper use of variables and methods.
