Stream.of(T... values) in Java with examples

Stream of(T… values) returns a sequential ordered stream whose elements are the specified values. A sequential stream work just like for-loop using a single core. On the other hand, a Parallel stream divide the provided task into many and run them in different threads, utilizing multiple cores of the computer.

Syntax :

static <T> Stream<T> of(T... values)

Where, Stream is an interface and T
is the type of stream elements.
values represents the elements of the 
new stream and the function 
returns the new stream.

Example 1 : Stream of strings.

// Java code for Stream.of() 
// to get sequential ordered stream 
import java.util.stream.Stream; 
  
class GFG { 
  
    // Driver code 
    public static void main(String[] args) 
    { 
        // creating a stream of Strings 
        // and printing sequential 
        // ordered stream 
        Stream<String> stream = Stream.of("Geeks", "for", "Geeks"); 
  
        stream.forEach(System.out::println); 
    } 
} 

Output :

Geeks
for
Geeks

Example 2 : Stream of Integers.

// Java code for Stream.of() 
// to get sequential ordered stream 
import java.util.stream.Stream; 
  
class GFG { 
  
    // Driver code 
    public static void main(String[] args) 
    { 
        // creating a stream of Integer 
        // and printing sequential 
        // ordered stream 
        Stream<Integer> stream = Stream.of(5, 7, 9, 12); 
  
        stream.forEach(System.out::println); 
    } 
} 

Output :

Example 3 : Stream of Long primitives.

// Java code for Stream.of() 
// to get sequential ordered stream 
import java.util.stream.Stream; 
  
class GFG { 
  
    // Driver code 
    public static void main(String[] args) 
    { 
        // creating a stream of Long 
        // and printing sequential 
        // ordered stream 
        Stream<Long> stream = Stream.of(4L, 8L, 12L, 16L, 20L); 
  
        stream.forEach(System.out::println); 
    } 
}
