DoubleStream of() in Java

DoubleStream of(double t)

DoubleStream of(double t) returns a sequential DoubleStream containing a single element.
Syntax :

static DoubleStream of(double t)

Parameters :

1. DoubleStream : A sequence of primitive double-valued elements.
2. t : Represents the single element in the DoubleStream.

Return Value : DoubleStream of(double t) returns a sequential DoubleStream containing the single specified element.

Example :

// Java code for DoubleStream of(double t)
// to get a sequential DoubleStream
// containing a single element.
import java.util.*;
import java.util.stream.DoubleStream;

class GFG {

    // Driver code
    public static void main(String[] args)
    {
        // Creating a DoubleStream having single
        // element only
        DoubleStream stream = DoubleStream.of(8.2);

        // Displaying the DoubleStream having
        // single element
        stream.forEach(System.out::println);
    }
}

Output :

8.2

DoubleStream of(double… values)

DoubleStream of(double… values) returns a sequential ordered stream whose elements are the specified values.
Syntax :

static DoubleStream of(double... values)

Parameters :

1. DoubleStream : A sequence of primitive double-valued elements.
2. values : Represents the elements of the new stream.

Return Value : DoubleStream of(double… values) returns a sequential ordered stream whose elements are the specified values.

Example 1 :

// Java code for DoubleStream of(double... values)
// to get a sequential ordered stream whose
// elements are the specified values.
import java.util.*;
import java.util.stream.DoubleStream;

class GFG {

    // Driver code
    public static void main(String[] args)
    {
        // Creating an DoubleStream
        DoubleStream stream = DoubleStream.of(8.2, 5.6, 4.1);

        // Displaying the sequential ordered stream
        stream.forEach(System.out::println);
    }
}

Output :

8.2
5.6
4.1

Example 2 :

// Java code for DoubleStream of(double... values)
// to get a sequential ordered stream whose
// elements are the specified values.
import java.util.*;
import java.util.stream.DoubleStream;

class GFG {

    // Driver code
    public static void main(String[] args)
    {
        // Creating an DoubleStream
        DoubleStream stream = DoubleStream.of(5.2, 4.2, 6.3);

        // Storing the count of elements in DoubleStream
        long total = stream.count();

        // Displaying the count of elements
        System.out.println(total);
    }
}

Output :
