Redundant 'Collection.addAll()' call
Reports Collection.addAll()
and Map.putAll()
calls immediately after an instantiation of a collection using a no-arg constructor.
Such constructs can be replaced with a single call to a parametrized constructor, which simplifies the code. Also, for some collections the replacement might be more performant.
Example:
Set<String> set = new HashSet<>();
set.addAll(Arrays.asList("alpha", "beta", "gamma"));
After the quick-fix is applied:
Set<String> set = new HashSet<>(Arrays.asList("alpha", "beta", "gamma"));

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
