Description

@soc-se-script

@VikramGoyal23 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

Example from src/main/java/task/Event.java lines 25-26:

        }
        else {

Example from src/main/java/task/Event.java lines 36-37:

        }
        else {

Example from src/main/java/task/Deadline.java lines 24-25:

        }
        else {

Suggestion: As specified by the coding standard, use egyptian style braces.

Aspect: Package Name Style

No easy-to-detect issues 👍

Aspect: Class Name Style

No easy-to-detect issues 👍

Aspect: Dead Code

No easy-to-detect issues 👍

Aspect: Method Length

Example from src/main/java/main/Tyler.java lines 23-162:

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.
