java8支持了函数式编程，lisp中最基本的元素就是list，car，cdr，cons

1.（car list）取出头

list.stream().findFirst().get()

2. (cdr list) 取出除头部外

list.stream().skip(1)

3. (cons x list) 

Stream.concat(Stream.of(x), list.stream())

java8构造Infinite Stream

Stream.iterate(1, i -> i + 2).filter(i -> i > 250).skip(10).limit(10)

Stream.generate…

注意不要用distinct，distinct不知道怎么和interate集成使用
