LowFile-scopeJava Plug & play

Use early return patterns for control flow

Validate and return early to reduce nesting and improve readability.

Why this matters

Flatter code is easier to reason about and maintain.

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

Avoid

if (req != null) { if (req.isValid()) { process(req); } }

Prefer

if (req == null || !req.isValid()) return error("invalid");
process(req);

Bad

deeply nested ifs

Good

guard clauses then main path

From the same buckets as this rule.

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 equality operators in loop termination conditions
Check if loops use equality operators (== or !=) in termination conditions. These can lead to infinite loops if the condition is never met exactly. Instead, use relational operators like < or > for safer loop termination.

Critical
Avoid Equality Operators in Loop Termination Conditions
Ensure that relational operators (`<`, `>`) are used instead of equality operators (`==`, `!=`) in loop termination conditions.
