在ItrToStream()函数中,我们将 iterable 转换为 spliterator。 之后,我们使用StreamSupport.stream()方法将 spliterator 转换为流。 最后,我们打印流。 importjava.util.*;importjava.util.stream.*;classTest{// function to convert iterable to streampublicstatic<T>Stream<T>ItrToStream(Iterable<T> iter){//...
一类是集合数据类型,如list、tuple、dict、set、str等; 一类是generator,包括生成器和带yield的generator function。 这些可以直接作用于for循环的对象统称为可迭代对象:Iterable。可以被next()函数调用并不断返回下一个值的对象称为迭代器:Iterator。 注意:在Python3中,next(Iterator)实际上调用的是Iterator.__next_...
