Returns a sequential Stream with this collection as its source.

Usage

From source file:Main.java

public static void main(String[] args) {
    List<Integer> numbers = Arrays.asList(1, 2, 3, 4, 5);
    boolean o = numbers.stream().anyMatch(n -> n % 2 == 0);

    System.out.println(o);// ww  w  . j  av  a 2 s  .c  o  m
}

From source file:Main.java

public static void main(String[] args) {
    List<String> stringList = Arrays.asList("1", "1", "2", "3", "4");

    stringList.stream().sorted(Comparator.reverseOrder()).forEach(System.out::println);
}

From source file:Main.java

public static void main(String[] args) {
    List<Integer> list = Arrays.asList(0, 1, 2, 3, 4, 5, 6, 7, 8, 9);

    list.stream().filter(x -> x % 3 == 0).sorted((x, y) -> y - x).map(x -> x * 3).forEach(System.out::println);
}

From source file:Main.java

public static void main(String[] args) {
    List<Integer> numbers = Arrays.asList(1, 2, 3, 4, 5);
    boolean o = numbers.stream().allMatch(n -> n % 2 == 0);

    System.out.println(o);/*from w  w  w.j av  a2s  .  co  m*/
}

From source file:Main.java

public static void main(String... args) {
    List<Integer> numbers = Arrays.asList(3, 4, 5, 1, 2);

    int max = numbers.stream().reduce(0, (a, b) -> Integer.max(a, b));
    System.out.println(max);/*from w  w w. ja v  a 2s . c  o m*/

}

From source file:Main.java

public static void main(String[] args) {
    List<Integer> numbers = Arrays.asList(3, 7, 9, 3, 1, 2, 1, 2, 3, 4, 5);
    numbers.stream().filter(n -> n % 2 == 1).sorted().forEach(System.out::println);
}

From source file:Main.java

public static void main(String[] args) {
    List<Point> points = Arrays.asList(new Point(12, 2));
    points.stream().map(p -> p.getX()).forEach(System.out::println);
}

From source file:Main.java

public static void main(String[] args) {
    List<Integer> numbers = Arrays.asList(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);
    numbers.stream().map(value -> value * 2).forEach(System.out::println);

}

From source file:Main.java

public static void main(String[] args) {
    List<String> stringList = Arrays.asList("1.2", "2.2", "3", "4", "5");

    stringList.stream().flatMap(n -> Stream.of(n)).forEach(System.out::println);
}

From source file:Main.java

public static void main(String[] args) {
    List<String> stringList = Arrays.asList("1.2", "2.2", "3", "4", "5");

    stringList.stream().flatMapToInt(n -> IntStream.of(Integer.parseInt(n))).forEach(System.out::println);
