Returns a sequential Stream with this collection as its source.

Usage

From source file:Main.java

public static void main(String[] args) {

    List<Integer> l = getDatas();

    System.out.println(l.stream().map((a) -> (a.toString())).reduce((a, b) -> (a + b)).orElse("ko"));

}

From source file:Main.java

public static void main(String[] args) {
    List<String> stringList = Arrays.asList("1", "2", "3", "4", "5");

    stringList.stream().mapToLong(n -> Long.parseLong(n)).filter(n -> n % 2 == 0).forEach(System.out::println);
}

From source file:Main.java

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

    stringList.stream().limit(2).peek(System.out::println);
}

From source file:Main.java

public static void main(String[] args) {
    List<String> stringList = Arrays.asList("5", "1", "2", "3", "4");

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

From source file:Main.java

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

    stringList.stream().skip(2).forEach(System.out::println);
}

From source file:Main.java

public static void main(String[] args) {
    List<String> stringList = Arrays.asList("1", "2", "3", "4", "5");

    stringList.stream().mapToInt(n -> Integer.parseInt(n)).filter(n -> n % 2 == 0).forEach(System.out::println);
}

From source file:Main.java

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

    stringList.stream().distinct().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().noneMatch(n -> n % 2 == 0);

    System.out.println(o);//  w  w  w  . j  ava  2s .  co  m
}

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<Integer> numbers = Arrays.asList(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);
    numbers.stream().filter(value -> value % 2 == 0).forEach(System.out::println);
