Redundant operation on empty container
Warning
New
Last modified: 03 December 2024Reports redundant operations on empty collections, maps or arrays.
Iterating, removing elements, sorting, and some other operations on empty collections have no effect and can be removed. Also, they may be a signal of a bug.
Example:
if (numbers.isEmpty()){
//error due to the missed negation
int max = numbers.stream().max(Comparator.naturalOrder()).get();
...
}
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
