In Java 9 we can easily initialize an ArrayList in a single line:

List<String> places = List.of("Buenos Aires", "Córdoba", "La Plata");

or

List<String> places = new ArrayList<>(List.of("Buenos Aires", "Córdoba", "La Plata"));

This new approach of Java 9 has many advantages over the previous ones:

  1. Space Efficiency
  2. Immutability
  3. Thread Safe
