jdk1.8中的for循环

public static void main(String[] args) {
        List<Animal> list = new ArrayList<Animal>();
        list.add(new Animal("miamiao",2));
        list.add(new Animal("wangwang",4));
        //1.8 a为泛型中的对象
        list.forEach(a ->{
            System.out.println(a.getName());
        });
        
        //1.5 增强行for循环
        for (Animal a : list) {
            System.out.println(a.getName());
        }
        //普通循环
        for(int i =0;i<list.size();i++){
            System.out.println(list.get(i).getName());
        }
    }
