As a Full Stack Developer, complete the features of the application. As this is a prototyped application, the user interaction will be via a command line.

Background of the problem statement:

For example Assiduous Securities Pvt. Ltd. hired you as a Full Stack Developer. They aim to digitize their products and chose SecureMe.com as their first project to start with. Youre asked to develop a prototype of the application.

• Java concepts being used in the project
• Data Structures where sorting and searching techniques are used.
• Generic features and three operations:
  • Retrieving the file names in an ascending order
  • Business-level operations:
    • Option to add a user specified file to the application
    • Option to delete a user specified file from the application
    • Option to search a user specified file from the application
    • Navigation option to close the current execution context and return to the main context
  • Option to close the application

The goal of the company is to deliver a high-end quality product as early as possible.

The flow and features of the application:

• Document the flow of the application and prepare a flow chart
• List the core concepts and algorithms being used to complete this application
• Code to display the welcome screen. It should display:
  • Application name and the developer details
  • The details of the user interface such as options displaying the user interaction information
  • Features to accept the user input to select one of the options listed
• The first option should return the current file names in ascending order. The root directory can be either empty or contain few files or folders in it
• The second option should return the details of the user interface such as options displaying the following:
  • Add a file to the existing directory list
    • You can ignore the case sensitivity of the file names
  • Delete a user specified file from the existing directory list
    • You can add the case sensitivity on the file name in order to ensure that the right file is deleted from the directory list
    • Return a message if FNF (File not found)
  • Search a user specified file from the main directory
    • You can add the case sensitivity on the file name to retrieve the correct file
    • Display the result upon successful operation
    • Display the result upon unsuccessful operation
  • Option to navigate back to the main context
• There should be a third option to close the application
• Implement the appropriate concepts such as exceptions, collections, and sorting techniques for source code optimization and increased performance

You must use the following:

• Java: A programming language to develop the prototype
• Search and Sort techniques: Data structures used for the project
• Specification document

Following requirements should be met:

• You need to document the steps and write the algorithms in it.
• Document the step-by-step process starting from sprint planning to the product release.
• Application should not close, exit, or throw an exception if the user specifies an invalid input.
• You need to submit the final specification document which includes:
  • Project and developer details
  • Algorithms and flowcharts of the application
  • Core concepts used in the project
  • Your conclusion on enhancing the application and defining the USPs (Unique Selling Points)
