Java 中的 LongStream forEachOrdered()方法
原文:https://www . geeksforgeeks . org/longstream-foreachordered-method-Java/
LongStream forEachOrdered(long consumer action)按照遭遇顺序对该流的每个元素执行一个操作。LongStream forEachOrdered(long consumer action)是一种 终端操作 ，即它可能会遍历流以产生结果或副作用。
语法:
void forEachOrdered(LongConsumer action)
参数: LongConsumer 表示接受单个长值参数且不返回结果的操作。这是消费者长期以来的原始型专业化。
注意:forEachOrdered(long consumer action)对该流的每个元素执行一个操作，在流的 相遇顺序 中，如果该流具有定义的相遇顺序。
例 1 :
// Java code for LongStream forEachOrdered
// (LongConsumer action) in Java 8
import java.util.*;
import java.util.stream.LongStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an LongStream
LongStream stream = LongStream.of(2L, 3L, 4L, 5L);
// Using LongStream.forEachOrdered
stream.forEachOrdered(System.out::println);
}
}
Output:
2
3
4
5
例 2 :
// Java code for LongStream forEachOrdered
// (LongConsumer action) in Java 8
import java.util.*;
import java.util.stream.LongStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an LongStream
LongStream stream = LongStream.range(5L, 11L);
// Using LongStream.forEachOrdered() on
// sequential stream
stream.forEachOrdered(System.out::println);
}
}
Output:
5

例 3 :
// Java code for LongStream forEachOrdered
// (LongConsumer action) in Java 8
import java.util.*;
import java.util.stream.LongStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an LongStream
LongStream stream = LongStream.range(5, 11);
// Using LongStream.forEachOrdered() on
// parallel stream
stream.parallel().forEachOrdered(System.out::println);
}
}
输出:
