A modern programming language that makes developers happier.

kotlinlang

Just converting the Java code to Kotlin seems a bit lame to me. :slightly_smiling_face:

What’s lame about it? Being compatible with Java is one of the greatest advantages of Kotlin:
```println(listOf("Zuhause", "Öl", "Auto", "Bank")
                .sortedWith(Collator.getInstance(Locale.GERMAN)))```

On iOS I always get blamed for not beeing _swifty_ enough. So, I just asumed. :slightly_smiling_face:

Thanks for your reply, works like a charme.

I have an array with objects, so I used this construction:

```val collator = Collator.getInstance(Locale("de", "DE"))
val sorted = filtered.sortedWith(compareBy(collator) { it.title })```

`filtered.map { collator.getCollationKey(it) }.sorted().map { it.sourceString }` sorts correctly and - according to Collator documentation - should be more efficient

`fun Iterable&lt;String&gt;.sortedWith(collator: Collator) = this.map { collator.getCollationKey(it) }.sorted().map { it.sourceString }` allows to use `filtered.sortedWith(collator)`
