Stream.of(T t) in Java with examples
Stream of(T t) returns a sequential Stream containing a single element i.e, a singleton sequential stream. 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 t) Where, Stream is an interface and T is the type of stream elements. t is the single element and the function returns a singleton sequential stream.
Example 1 : Singleton string stream.
// Java code for Stream.of()// to get sequential Stream// containing a single element.import java.util.stream.Stream; class GFG { // Driver code public static void main(String[] args) { // creating a stream of Strings // and printing sequential Stream // containing a single element Stream<String> stream = Stream.of("Geeks"); stream.forEach(System.out::println); }} |
Output :
Geeks
Example 2 : Singleton Integer Stream.
// Java code for Stream.of()// to get sequential Stream// containing a single element.import java.util.stream.Stream; class GFG { // Driver code public static void main(String[] args) { // creating a stream of Integer // and printing sequential Stream // containing a single element Stream<Integer> stream = Stream.of(5); stream.forEach(System.out::println); }} |
Output :
5
Example 3 : Singleton Long stream.
// Java code for Stream.of()// to get sequential Stream// containing a single element.import java.util.stream.Stream; class GFG { // Driver code public static void main(String[] args) { // creating a stream of Long // and printing sequential Stream // containing a single element Stream<Long> stream = Stream.of(4L); stream.forEach(System.out::println); }} |
Output :
4
