Converting 'ArrayList to 'String[]' in Java

Question

How might I convert an ArrayList object to a String[] array in Java?

Answer 1

Starting from Java-11, one can alternatively use the API Collection.toArray(IntFunction generator) to achieve the same as:

List list = List.of("x","y","z");
String[] arrayBeforeJDK11 = list.toArray(new String[0]);
String[] arrayAfterJDK11 = list.toArray(String[]::new); // similar to Stream.toArray
