Subsequent steps can be fused into Stream API chain
Detects transformations outside a Stream API chain that could be incorporated into it.
Example:
List<String> list = stream.collect(Collectors.toList());
list.sort(null);
return list.toArray(new String[list.size()]);
After the conversion:
return stream.sorted().toArray(String[]::new);
Note that sometimes the converted stream chain may replace explicit ArrayList
with Collectors.toList()
or explicit HashSet
with Collectors.toSet()
. The current library implementation uses these collections internally. However, this approach is not very reliable and might change in the future altering the semantics of your code.

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
FuseStreamOperations
If you are concerned about it, use the Do not suggest 'toList()' or 'toSet()' collectors option to suggest Collectors.toCollection()
instead of toList
and toSet
collectors.
This inspection depends on the Java feature 'Stream and Optional API', which is available since Java 8.
