Converting between structurally compatible function types

Hello there,

I have a very basic question: why does the following not compile:

Function<String,Integer> f = s -> 1;
Function<String,Object> g = f;

After all, I would expect that anywhere where a function from String to arbitrary objects is required, I can supply a function to integers in particular.
I guess Java just sees the names are different, and that’s it?

How do I best convert between the two types?
