code review for chenhowy part 2 and team

[yicheng-toh]

1. I realised that there are a lot of changes to code ownership. Do consider using these notations to mark out your code.

Similar feedback to your peers, there seems to be some form of parsing in this method. Perhaps the parser class can take care of it.
Please take a look at Single Responsibility Principle and cohesion regarding the class design choices.

Perhaps you might want to consider looking at past tp or AB3 for reference.

3. Similar to Point 2

The parser is doing switch statements and also doing error catching. Perhaps you might consider putting it together with the parser? This is so that there would be only one reason to change the functions.
