java的lambda表达式

public class Test {
    public static void main(String[] args) {
        List list = new ArrayList<>();
        list.add("one");
        list.add("two");
        list.add("three");

        //for循环
        for (String s : list) {
            System.out.println(s);
        }

        //lambda表达式
        list.forEach(s -> System.out.println(s));

        //lambda表达式的eta转换
        list.forEach(System.out::println);
    }
}
