LongStream of() in Java

LongStream of(long t)

LongStream of(long t) returns a sequential LongStream containing a single element.
Syntax :

static LongStream of(long t)

Parameters :

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

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

Example :

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

class GFG {

    // Driver code
    public static void main(String[] args)
    {
        // Creating an LongStream having single element only
        LongStream stream = LongStream.of(-7L);

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

Output:

-7

LongStream of(long… values)

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

static LongStream of(long... values)

Parameters :

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

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

Example 1 :

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

class GFG {

    // Driver code
    public static void main(String[] args)
    {
        // Creating an LongStream
        LongStream stream = LongStream.of(-7L, -9L, -11L);

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

Output:

-7
-9
-11

Example 2 :

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

class GFG {

    // Driver code
    public static void main(String[] args)
    {
        // Creating an LongStream
        LongStream stream = LongStream.of(-7L, -9L, -11L);

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

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

Output:

3
