Generate return type signature in Scala with Intellij Idea

Question

While Scala has a type inference, it is considered good practice to explicitly define the return type of public functions. Is it possible to get IDEA add the explicit return type from the inferred one?

Answer 1

If you are on a method name then you can hit ALT + ENTER to get the Intention Actions where the first is usually the Add type annotation to function definition

Illustration:

In this case it would add Int to the return type of the exampleFunction.

Might I add this also works for val/var declarations, essentially whenever there is a type inferred.
