Stream流中的常用方法_forEach
|
||||||
|
void forEach(Consumer<? super T> action) 对此流的每个元素执行操作。
|
||||||
|
|
||||||
|
知识点回顾:
|
||||||
|
Consumer:接收一个参数,没有返回值
|
||||||
|
抽象方法:void accept(T t) ---> t->{}
|
||||||
|
|
||||||
|
foreach的执行原理:它会将Stream流中的每个元素,作为以上Consumer的参数执行方法体
|
||||||
|
foreach的作用:是对流中的元素进行遍历消费
