IntStream asLongStream() in Java

  • Last Updated : 06 Dec, 2018

IntStream asLongStream() returns a LongStream consisting of the elements of this stream, converted to long. This is an intermediate operation. Intermediate operations are invoked on a Stream instance and after they finish their processing, they give a Stream instance as output.

Syntax :

LongStream asLongStream()

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

Return Value : IntStream asLongStream() returns a LongStream consisting of the elements of this stream, converted to long.

Example 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);
    }
}

Output :



3
5
9
12
14

Example 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);
    }
}

Output :

3
4
5
