Project: VirusTracker

VirusTracker is a desktop app for generating statistics for Covid-19, optimized for use via a Command Line Interface (CLI) while still having the benefits of a Graphical User Interface (GUI). The GUI is created with JavaFX. It is written in Java, and has about 10 kLoC.

Given below are my contributions to the project.

  • New Feature: Added the ability to list infected people in VirusTracker.
    • What it does: It displayed all persons whose infection status is true on the GUI.
    • Justification: This feature allows users to list and view all the infected people on the GUI.
  • New Feature: Added the ability to list quarantined people in VirusTracker.
    • What it does: It displayed all persons whose quarantine status is true on the GUI.
    • Justification: This feature allows users to list and view all the quarantined people on the GUI.
  • New Feature: Added the ability to list high risk locations in VirusTracker.
    • What it does: It displayed a number of top most infected locations on the GUI. The number can be specified by the user. If the number is not specified, VirusTracker will determine the number using a pre-defined rule.
    • Justification: This feature allows users to list and view high risk locations (i.e. the top few most infected locations) in VirusTracker.
  • New Feature: Added the ability to automatically delete all visits associated to the location when this location is deleted by the execution a deleteLocation command. This is also known as cascade delete for location.
    • Justification: This feature saves the trouble for users to delete visits associated with the deleted location manually.
  • New Feature: Added the ability to automatically delete all visits associated to the person when this person is deleted by the execution a deletePerson command. This is also known as cascade delete for person.
    • Justification: This feature saves the trouble for users to delete visits associated with the deleted person manually.
  • New Feature: Added the ability to automatically update all visits associated to the location when this location is edited by the execution a editLocation command.
    • What it does: It iterates through the list of visits and replace the not yet edited location with edited location into those visits associated to this location.
    • Justification: This feature ensures that all visits stored in the visit book are consistent with locations in the location book.
  • Enhancements to existing features: Added a unique identifier field for Person class.
    • Justification: This can allow VirusTracker and users to uniquely identify a person. The unique identification of a person is first planned to be used for getPerson method in Visit class, which was not carried out. It was then used in addPerson, deletePerson and editPerson command.
  • Enhancements to existing features: Added exception handling for date parsing for addVisit command
    • Justification: This ensures that the system will not crash when user type in the wrong date in wrong format in addVisit command.
