Features implemented

**1. Enabled users to add and delete classes from timetable **

#75

What it does:

This is a feature for managing a timetable or class schedule in a Java application. It allows the user to add and delete classes from a timetable, with each class having attributes such as the day of the week, time, duration, and location. The added classes can also be stored and accessed later even after the user closes the program.

2. Handles exceptions when input has invalid format

#36

What it does:

The code uses a custom exception InvalidInputFormatException to handle specific cases where the input format does not meet the expected criteria. This exception is thrown when the input string for the expenditure does not contain the required keywords (“d/”, “amt/”, “date/”) in the correct order or format.

3. J-unit Tests for Processing command

What it does:

Created JUnit tests created include test cases for TimetableParser, GPAMain, Module, ModuleList, YlogX, YX, YXsq.

JUnit tests for GC-related classes:

• Checked that the panel instances (YlogX, YX, YXsq) are not null after they have been instantiated.
• Verified that the panels have a set preferred size of 400x400 pixels.
• Ensured that drawing operation does not throw any exceptions, which is crucial for validating that the painting logic (including drawing graphs, axes, labels, etc.) does not encounter runtime errors or illegal states by simulating the painting process. #257

JUnit tests for GPA-related classes:

• Ensured that the Module and ModuleList classes manage modules correctly, accurately reporting their state through counts and total credits. #276

JUnit tests for TimetableParser

• Ensured that TimetableParser handles erroneous inputs such as incorrect or missing commands by providing the correct feedback and also ensures that system still behaves as expected #277

Contributions to User Guide

• Created the product introduction for our application CantVas #105
• Added Q&A and user stories for the TimeTable feature. #105 #63 #258

Contributions to Developer Guide

• Added Class Diagram and its explanation for GPA-related classes(GPACommand, GPAMain, Module, ModuleList, ProcessListCommand) #275
• Added Class Diagram and its explanation for GC-related classes(ProcessGCCommand, YlogX, YX, YXsq) #282
• Added Sequence Diagram for GC-related classes(ProcessGCCommand, YlogX, YX, YXsq) and explained how GC works. #283 #282

Contributions to team-based tasks

• Completed tasks that were assigned to me quickly.
• Creation and testing of artefact JAR files before each milestone (v1.0, v2.0 and v2.1).
• Corrected names of methods and classes to make them more comprehensible. #54
• Actively participated in our weekly team meetings.
• Helped with documentation of the codes so as to make the codes more readable and easier to understand #262 #263 #266 #279 #281
