hi all, is there a performance hit when method reference is used vs lambda?

Assuming you're comparing something like:

runSomething(::blah)
runSomething { blah() }

Then not really - view the byte code and you can see they both generate a new inner class that just invokes the original function

[alex2069]

I think if you target Java 8 then the reference might use invoke dynamic or something fancy instead which might be more efficient, though not 100% sure on that

I thought invoke dynamic was only added in Java 9 or a later version 🤔

Java 8 - lambdas are based on it

thanks all
