Method can be extracted
Suggests extracting fragments of code to a separate method to make code more clear. This inspection has a number of heuristics to select good candidates for extraction, including the following ones.
The extracted fragment has no non-local control flow
The extracted fragment has exactly one output variable
There are no similar uses of output variable inside the extracted fragment and outside it
The extracted fragment has only few input parameters (no more than three by default; configured with the inspection option)
The extracted fragment is not smaller than the configured length (500 characters by default) but no bigger than 60% of the containing method body
