Project: NUStudy

NUStudy, an NUS CS2113 team project (tP), by team W14-2, AY2526S1, is a desktop app for managing study hours, optimised for use via a command-line interface (CLI). It is written in Java.

Given below are my contributions to the project.

• New Feature: Implemented the resetCourseHoursCommand class: #36, #28.
  • What it does: Allows users to reset the logged study hours for a specified course or all courses.
  • Justficiation: This feature improves usability by giving users flexibility to start new every semester or clear hours for a specific course without deleting the course entirely.
  • Highlighs: This implementation required integrating the feature across multiple components while maintaining the course-session connection. It also involves handling exceptions with a double confirmation flow to prevent accidental data wipe.
  • Credits: Design inspired from this article. Implementation completed fully by me.
• New Feature: Implemented the data loading component under the Storage class: #63.
  • What it does: Loads and parses stored course and sessiond data automatically from a local storage file NUStudy. txt when a new application session starts. This allows users to resume study progress tracking seamlessly across multiple application sessions.
  • Justification: Without automatic data loading, all previously recorded study hours will be wiped when the application session closes. This feature improves user experience and persistence.
  • Highlights: This implementation requires careful handling of file I/O operations and parsing logic. It uses a buffer of class BufferedReader to safely transfer the data over. To handle exceptions, corrupted entires are skipped to prevent application session crashes at runtime.
  • Credits: Idea of BufferedReader is obtained from this article. Implementation is completed fully by me. My teammate, Foo Kang, contributed to minor bug fixes.
• Code Contributed: RepoSense link
• Enhancement to existing features:
  • Implemented DeleteSessionByIndexCommand and DeleteSessionByDateCommand classes for enhanceed flexibility for deleting sessions by date for all couress or a specified index for a specified course: #85.
  • Added JUnit 5 test cases for my implemented features and enhancements. Raised total method coverage to 100%: #90.
• Documentation:
  • User Guide:
    • Added documentation for features delete course by index, delete course by date and reset course hours: #90.
    • Added documentation for data integrity and safety for clear understanding of how data loading is handled: #180.
  • Developer Guide:
    • Added implementation details, activity flow diagram and design considerations of the reset feature: #71.
    • Added implementation details and sequence diagram for the data loading component feature: #71.
    • Added list of validation checks and execution upon detection of invalid entries: #180.
• Community:
  • PRs reviewed (with non-trivial review comments): #65.
  • The confirmation handler feature I implemented was adopted by my teammate, Kandasami: #86.
