Usage

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) {
    Function<Integer, String> converter = (i) -> Integer.toString(i);

    Function<String, Integer> reverse = (s) -> Integer.parseInt(s);

    System.out.println(converter.apply(3).length());
    System.out.println(converter.andThen(reverse).apply(30).byteValue());
}

From source file:Main.java

public static void main(String[] args) {
    Function<Integer, String> converter = (i) -> Integer.toString(i);

    Function<String, Integer> reverse = (s) -> Integer.parseInt(s);

    System.out.println(converter.apply(3).length());
    System.out.println(converter.compose(reverse).apply("30").length());
}

From source file:Main.java

    while (true) {
        int c;/*from  w w  w  .  jav  a 2s  .  c  om*/
        c = zip.read();
        if (c == -1)
            break;

    }
}

From source file:Main.java

public static void main(String[] args) {

    System.out.println(o);/*from w  w w  . ja v a 2s .co  m*/
}

        DataOutputStream dos = new DataOutputStream(os);
        dos.writeInt(1);

        s.close();
    }
}

From source file:Main.java

public static void main(String[] args) {

    double o = s.collect(Collectors.averagingInt(n -> Integer.parseInt(n)));

    System.out.println(o);/*from  w  ww .j ava 2 s.  c o  m*/
}
