Method reference can be replaced with lambda

Reports method references, like MyClass::myMethod and myObject::myMethod, and suggests replacing them with an equivalent lambda expression.

Lambda expressions can be easier to modify than method references.



After the quick-fix is applied:

s -> System.out.println(s)

Locating this inspection
