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.
