Description
Reports while loops whose body is empty.
A while (condition) { } re-evaluates its condition repeatedly but performs no work in the body. Unless the condition expression itself has a side effect, the loop will either run forever or terminate immediately — neither of which is intentional.
Rationale
// Bad — empty body, condition checked but nothing consumed
while (queue.isNotEmpty()) { } // FLAW
// Good — non-empty body
while (queue.isNotEmpty()) {
process(queue.poll())
}Remediation
Either fill in the missing body, or remove the while loop entirely if the condition check was no longer needed after a refactoring.
