Why is this an issue?
The size of a collection or an array is always greater than or equal to zero. So testing that a size is greater than or equal to zero doesn’t make
sense, since the result is always true
. Similarly testing that it is less than zero will always return false
. Perhaps the
intent was to check the non-emptiness of the collection or array instead.
Noncompliant code example
if (myList.size >= 0) { ... }
if (myList.size < 0) { ... }
boolean result = myArray.size >= 0;
if (0 > myArray.size) { ... }
Compliant solution
if (!myList.isEmpty()) { ... }
if (myArray.size >= 42) { ... }
