A modern programming language that makes developers happier.

kotlinlang

Dumb question. I declare a property in an abstract class as `protected var counter: Int`, which is naturally visible in the implementation classes, but not outside. If I try to access protected member from "outside", I get `Can not access 'counter': it is protected in ...` compilation error. This is in Kotlin-only code. However from Java I can see all the protected members as well and can access `getCounter()` and `setCounter()`. Seems like a strange behavior to me and I couldn't fine anything in the docs.

Or is the Java code in the same package as the Kotlin superclass?

Because in Java, `protected` is also implictly `package-private` (i.e. not so protected)

BTW, if you want to guard from Java callers using the same package name, you can try the `@JvmSynthetic` annotation.

But then you don't allow Java subclasses either.

You don't allow access to this field/property/method from Java, yes.
