学习内容:Stream流中的常用方法_forEach
|
||||||
|
void forEach(Consumer action) 对此流的每个元素执行消费操作。
|
||||||
|
|
||||||
|
知识点回顾: Consumer:接收一个参数用来操作,并没有返回值
|
||||||
|
抽象方法:void accept(T t) --->对应的lambda对应的格式:t->{}
|
||||||
|
foreach的执行原理:它会将stream流 中的每个元素作为以上lambda的参数执行方法体.

//需求:将整数进行相加10,再打印操作

public class ForEachDemo18 {

public static void main(String[] args) {
|

|
//获取流
|
||||||
|
Stream<Integer> stream = Stream.of(1, 2, 3, 4, 5);
|
||||||
|
//遍历操作
|
||||||
|
stream.forEach((Integer i)->{
|
||||||
|
System.out.println(i+10);

});
