Subsequent steps can be fused into Stream API chain
Detects transformations outside a Stream API chain that could be incorporated into it.
After the conversion:
Note that sometimes the converted stream chain may replace explicit
Collectors.toList() or explicit
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.
If you are concerned about it, use the Do not suggest 'toList()' or 'toSet()' collectors option to suggest
Collectors.toCollection() instead of
This inspection only reports if the language level of the project or module is 8 or higher.
Do not suggest 'toList()' or 'toSet()' collectors
