LowFile-scopeJava Plug & play

Use named constants for magic values

Replace numeric/string literals with named constants to document meaning.

Why this matters

Improves readability and centralizes changes.

Side-by-side examples engineers can pattern-match during review.

Avoid

Thread.sleep(2000);

Prefer

private static final int RETRY_DELAY_MS = 2000;
Thread.sleep(RETRY_DELAY_MS);

Bad

if (retries > 3)

Good

if (retries > MAX_RETRIES)

From the same buckets as this rule.

Critical
Avoid Duplicating String Literals
Store repeated string literals in constants or variables to improve maintainability and reduce redundancy.

Critical
Avoid Empty Methods
Detect methods that have an empty body. If a method is empty, ensure that a comment is present explaining why it remains unimplemented.

Critical
Avoid modifying built-in prototypes
Detect modifications to built-in prototypes. Modifying built-in objects can lead to compatibility issues and unexpected behavior. Recommend creating helper functions instead.
