Sharing iP code quality feedback [for @LowXiSi]

[nus-se-bot]

@LowXiSi We did an automated analysis of your code to detect potential areas to improve the code quality. We are sharing the results below, to help you improve the iP code further.

IMPORTANT: Note that the script looked for just a few easy-to-detect problems only, and at-most three example are given i.e., there can be other areas/places to improve.

Aspect: Tab Usage

No easy-to-detect issues 👍

Aspect: Naming boolean variables/methods

No easy-to-detect issues 👍

Aspect: Brace Style

No easy-to-detect issues 👍

Aspect: Package Name Style

Aspect: Dead Code

Example from src/test/java/loafy/parser/ParserTest.java lines 19-19:

        // single digits for date and month results in correct LocalDateTime;

Example from src/test/java/loafy/parser/ParserTest.java lines 24-24:

        // padded date and month results in correct LocalDateTime;

Example from src/test/java/loafy/parser/ParserTest.java lines 29-29:

        // padded time and hour results in correct LocalDateTime;

Suggestion: Remove dead code from the codebase.

Aspect: Method Length

Example from src/main/java/Loafy/parser/Parser.java lines 24-100:

    public static Command parse(String line) throws LoafyException {
        String[] arr = line.split(" ");

        if (arr.length == 0) {
            throw LoafyException.ofEmptyInput();
        } else if (line.equals("bye")) {
            return new ExitCommand();

Suggestion: Consider applying SLAP (and other abstraction mechanisms) to shorten methods e.g., extract some code blocks into separate methods. You may ignore this suggestion if you think a longer method is justified in a particular case.
