Java 中的 IntStream asLongStream()
哎哎哎:# t0]https://www . geeksforgeeks . org/intstream-asongstream-Java/
IntStream asLongStream() 返回一个由该流的元素组成的 LongStream ，转换为 long。这是一个 的中级操作。 在流实例上调用中间操作，在它们完成处理后，它们给出一个流实例作为输出。
语法:
LongStream asLongStream()
Where, LongStream is a sequence of
primitive long-valued element.
返回值: IntStream asLongStream()返回一个由这个流的元素组成的 LongStream，转换为 long。
例 1 :
// Java code for LongStream asLongStream()
// to return a LongStream consisting of
// the elements of this stream
import java.util.*;
import java.util.stream.IntStream;
import java.util.stream.LongStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an IntStream
IntStream stream = IntStream.of(3, 5, 9, 12, 14);
// Using LongStream asLongStream()
LongStream stream1 = stream.asLongStream();
// Displaying LongStream consisting of
// the elements of this stream
stream1.forEach(System.out::println);
}
}
输出:
3
5
9
12
14
例 2 :
// Java code for LongStream asLongStream()
// to return a LongStream consisting of
// the elements of this stream
import java.util.*;
import java.util.stream.IntStream;
import java.util.stream.LongStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an IntStream and using asLongStream()
LongStream stream = IntStream.range(3, 8).asLongStream();
// Displaying LongStream consisting of
// the elements of this stream
stream.forEach(System.out::println);
}
}
输出:
3
