A modern programming language that makes developers happier.

kotlinlang

So... I thought I knew how interfaces worked... but to my surprise something unexpected is happening. I'm able to compile my code with a new method defined in my interface and I didn't have to override it... can anyone explain?

```interface MyScreen {
    fun onClickOfSomething(path: String) {}```
What's up with that?

the `{}` provides an empty, default implementation of your function.

oh crap. interfaces can have defaults now?

been that way for quite a while, in both Kotlin and Java.

although since Kotlin originally targeted Java 6, the way it works is not entirely compatible (e.g. a Kotlin interface with default implementations may not be easily implemented in Java under some circumstances)

it should "just work" with current versions unless you're doing something unusual, though

interesting. i somehow completely eluded that language feature. TIL. thanks for teaching
