Project: Track-O

Track-O is a desktop address book application used by private tutors to schedule lessons and track payments. The user interacts with it using a CLI, and it has a GUI created with JavaFX. It is written in Java, and has about 17 kLoC.

Given below are my contributions to the project.

  • Tracking payments: Added the ability to track payments for Tutees.
    • What it does: allows the user to store payment amounts due by their tutees and keep track of the due date.
    • Justification: This feature implements a core functionality for the application as tutors need not rely on manual bookkeeping, reducing mistakes in calculations and providing more convenience to the users.
    • Highlights: This enhancement affects existing commands and commands to be added in future, such as PaymentAddCommand and PaymentSetAmountCommand. It required an in-depth analysis of design alternatives, especially in regard to how the payment amount would be accumulated by the tutee and how the user would track it.

      For example, initial plans involved having a fixed payment due date of 1 week since a payment was made, to be calculated automatically using LocalDate, but considering not all tutors collect their fees weekly, the final design let them set their own payment due dates.
    • The implementation was challenging to utilize payment as a parent command and parse it into 5 separate functionalities.

  • Get: Added the ability to view more information.
    • What it does: allows the user to keep track of additional information without it clogging existing GUI tutee panel.
    • Justification: Information of tutee may span multiple lines, especially to track progress of the tutee. If it were displayed on the GUI tutee panel, this would reduce readability. Hence, the get command allows for information to be displayed without affected general overview of GUI.
    • Highlights: This enhancement allowed for more fields to be added such as lesson information and remarks which takes up more space, compared to shorter information like address.
