1、用lambda表达式实现Runnable
new Thread(new Runnable() {
    @Override
    public void run() {
        System.out.println("I am jdk7 running.");
    }
}).start();

new Thread(() -> {
    System.out.println("I am jdk8 running.");
}).start();

2、使用lambda表达式对列表进行迭代
List<String> names1 = Arrays.asList("Tom", "May", "John");
for (String name : names1) {
    System.out.println(name);
}

List<String> names2 = Arrays.asList("Tom", "May", "John");
names2.forEach(n -> System.out.println(n));
names2.forEach(System.out::println);
