The worst thing is, that System.arraycopy() is an optimized JNI call which is much faster than copying it by hand [1].

The thing is though, most of the time arrays in Java are used because of performance. Or maybe ignorance. Because why would anyone voluntarily give up all the comforts of a List<T>? It's not that Collections are very hard to find in the documentation. And most of the IntelliJ suggest switching to a Collection anyway.
