IntStream 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 : IntStream 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 stream import java.util.*;
import java.util.stream.IntStream;
import java.util.stream.DoubleStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an IntStream
IntStream stream = IntStream.of( 3 , 5 , 9 , 12 , 14 );
// 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 :
// Java code for DoubleStream asDoubleStream() // to return a DoubleStream consisting of // the elements of this stream import java.util.*;
import java.util.stream.IntStream;
import java.util.stream.DoubleStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an IntStream and using asDoubleStream()
DoubleStream stream = IntStream.range( 3 , 8 ).asDoubleStream();
// Displaying DoubleStream consisting of
// the elements of this stream
stream.forEach(System.out::println);
}
} |
Output :
3.0 4.0 5.0 6.0 7.0
Example 3 :
// Java code for DoubleStream asDoubleStream() // to return a DoubleStream consisting of // the elements of this stream import java.util.*;
import java.util.stream.IntStream;
import java.util.stream.DoubleStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an IntStream and using asDoubleStream()
// to display the elements of IntStream and
// DoubleStream together
DoubleStream stream = IntStream.range( 3 , 8 )
.peek(System.out::println)
.asDoubleStream();
// Displaying DoubleStream consisting of
// the elements of this stream
stream.forEach(System.out::println);
}
