if I have a fun args(args: Iterable<String>) and i pass it an Array<String> it says array is not a subtype of iterable. What's the solution to this problem?

[diesieben07]

Several possibilities. 1 - Make args of type Array<String>. 2 - Pass something that is actually an Iterable<String>, e.g. List<String>. 3 - Use Array::asIterable.

Are there solutions (other than #1) that do with the method signature?

[diesieben07]

No, if the method signature declares an Iterable you cannot pass something that's not an Iterable. That's like passing a String where a List is expected. The types do not match up.

But isnt an array an iterable?

[diesieben07]

No, it is not.

[diesieben07]

Complain to Java 😛

I know it isnt in Kotlin, but java it is right? isnt that how old school for is possible during compile-time

[diesieben07]

No. The foreach-loop on arrays is special cased, it does not compile to an iterator method call.

Ah

Well #3 is my solution 🙂 Thanks
