Create a LongStream and add some elements.

LongStream longStream = LongStream.of(50L, 30L, 80L, 40L, 15L, 60L);

Now, get the count of elements.

      LongStream longStream = LongStream.of(50L, 30L, 80L, 40L, 15L, 60L);
      System.out.println("The number of elements in the stream = "+longStream.count());
