Returns a stream of int zero-extending the char values from this sequence.

Usage

From source file:Main.java

public static void main(String[] args) {

    String s = "R2D2C3P0";
    int result = s.chars().filter(Character::isDigit).map(ch -> Character.valueOf((char) ch)).sum();

    System.out.println(result);//from  w w w.  ja v a 2  s .  com
}

From source file:Main.java

public static void main(String[] args) {
    String str = "5 123,123,qwe,1,123, 25";
    str.chars().filter(n -> !Character.isDigit((char) n) && !Character.isWhitespace((char) n))
            .forEach(n -> System.out.print((char) n));
