How to get a String[] consisting of the .toString() calls of an ArrayList<Object> in one line

So i'm wondering if its possible to populate a String array made from toString() calls of an object ArrayList

So I know this can be done using a loop but is there a one line approach?

Loop approach

ArrayList<Object> objects = new ArrayList<Object>();
//fill object with elements 
//

String[] strings = new String[object.length()];
for(int i = 0;i<10;i++)strings[i]=objects.get(i).toString();

Using java-8, 

String[] strings = objects.stream().map(Object::toString).toArray(String[]::new);
