Java 8 functional interface with no arguments and no return value

Question

What is the Java 8 functional interface for a method that takes nothing and returns nothing? I.e., the equivalent to the C# parameterless `Action` with `void` return type?

Accepted Answer

If I understand correctly you want a functional interface with a method `void m()`. In which case you can simply use a `Runnable`.
