kotlinlang

how do you refactor change signature of a java method so that kotlin knows if it is `?` or not ? if I change `double` to `@Nullable Double` then in the kotlin code it becomes `@Nullable Double?` and then i must do a search and replace. This is for the return value but from past experience I think that happens in parameters as well

by default kotlin assumes java code is platform type signified as a `!` in the IDE, this will crash at runtime with a nullpointer whne trying to assing to a kotlin `Double`

as for how to make this work in refactoring..  i am only aware of finding all usages of the method and adjusting the types on each callsite
