Usage

From source file:Main.java

public static void main(String[] args) {
    Stream<String> s = Stream.of("a");
    s.limit(10).forEach(System.out::println);

}

From source file:Main.java

public static void main(String[] args) {
    Integer[] numbers = { 1, 2, 3, 4 };
    Stream<Integer> arrayStreams1 = Stream.of(numbers);

    System.out.println(Arrays.toString(arrayStreams1.toArray()));
}

From source file:Main.java

public static void main(String[] args) {

    int[] intArray = { 1, 2, 3, 4 };
    Stream<int[]> singleElementStream = Stream.of(intArray);

    // OUTPUTS/*ww w  .  j  ava 2 s . c  o m*/

    System.out.println(Arrays.toString(singleElementStream.toArray(Integer[]::new)));
    singleElementStream.toArray(); // watch it, it is Object[]
}

From source file:Main.java

public static void main(String[] args) {
    Integer[] numbers = new Integer[] { 2, 7, 3, 9, 5, 4, 6, 8, 1 };

    Stream.of(numbers).forEach(System.out::println);
}

From source file:Main.java

public static void main(String[] args) {
