Describe the issue

The old code only shows how a list is converted to an array, without the filtering which happens in the stream variant.
This could quite simply be done with String[] arr = list.toArray(new String[0]);

So either we also filter in the old version - which would then indeed require a for loop. Or the we don't filter in the new version, in which case I'd argue that getNames().toArray(new String[0]); is actually simpler/better than getNames().stream().toArray(String[]::new);.
