Sharing iP code quality feedback [for @RyanNgWH] - Round 2

Opened this issue ยท 0 comments

@RyanNgWH We did an automated analysis of your code to detect potential areas to improve the code quality. We are sharing the results below, so that you can avoid similar problems in your tP code (which will be graded more strictly for code quality).

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 ๐Ÿ‘

Aspect: Naming boolean variables/methods

Example from src/main/java/ciara/commands/ArchiveCommand.java lines 23-23:

    private boolean toArchive;

Example from src/main/java/ciara/ui/gui/MainWindow.java lines 73-73:

        Boolean toExit = false;

Suggestion: Follow the given naming convention for boolean variables/methods (e.g., use a boolean-sounding prefix).You may ignore the above if you think the name already follows the convention (the script can report false positives in some cases)

Aspect: Brace Style

No easy-to-detect issues ๐Ÿ‘

Aspect: Package Name Style

Aspect: Class Name Style

Aspect: Dead Code

Aspect: Method Length

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.

Aspect: Class size

Suggestion: Consider breaking large classes into smaller ones, if appropriate. A long class is a sign that perhaps it is dong 'too much'.
