Java中的 IntStream asLongStream()

IntStream asLongStream()返回由该流的元素组成的LongStream ，转换为 long。这是一个中间操作。在 Stream 实例上调用中间操作，在它们完成处理后，它们给出一个 Stream 实例作为输出。

句法：

LongStream asLongStream()

Where, LongStream is a sequence of 
primitive long-valued element.

返回值： IntStream asLongStream() 返回一个由该流的元素组成的 LongStream，转换为 long。

示例 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：

示例 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：
