Usage

From source file:Main.java

public static void main(String[] args) {

    List<String> friends = Arrays.asList("A", "B", "C", "D");

    //external iterate with index == evil
    for (int i = 0; i < friends.size(); i++) {
        System.out.println(friends.get(i));
    }//w ww . j a  va2s. co  m

    //external iterate on collection, better but ... external
    for (String friend : friends) {
        System.out.println(friend);
    }

    //lambda
    friends.forEach(s -> System.out.println(s));

    //lambda reference
    friends.forEach(System.out::println);
