LongStream asDoubleStream() returns a DoubleStream consisting of the elements of this stream, converted to double. 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 :
DoubleStream asDoubleStream() Where, DoubleStream is a sequence of primitive double-valued element.
Return Value : LongStream asDoubleStream() returns a DoubleStream consisting of the elements of this stream, converted to double.
Example 1 :
// Java code for DoubleStream asDoubleStream()// to return a DoubleStream consisting of// the elements of this streamimport java.util.*;import java.util.stream.LongStream;import java.util.stream.DoubleStream;  class GFG {      // Driver code    public static void main(String[] args)    {        // Creating a LongStream        LongStream stream = LongStream.of(3L, 5L, 9L, 12L, 14L);          // Using DoubleStream asDoubleStream()        DoubleStream stream1 = stream.asDoubleStream();          // Displaying DoubleStream consisting of        // the elements of this stream        stream1.forEach(System.out::println);    }} |
Output :
3.0 5.0 9.0 12.0 14.0
Example 2 :
