Empty Streams

Description

An empty stream has no elements.

Example

We can use empty() static method from Stream interface to create an empty sequential stream.

import java.util.stream.Stream;
/* w w w . j  a v  a 2  s.co m*/
public class Main {
  public static void main(String[] args) {
    Stream<String> stream  = Stream.empty();
    stream.forEach(System.out::println);
  }
}

Note

The IntStream, LongStream, and DoubleStream interfaces also contain an empty() static method to create an empty stream of primitive types.

The following code creates an empty stream of integers.
