Usage

From source file:Main.java

public static void main(String[] args) {

    String s = "Hello true World! 1 + 1 = 2.0 ";

    Scanner scanner = new Scanner(s);

    while (scanner.hasNext()) {

        // if the next is boolean, print found and the boolean
        if (scanner.hasNextBoolean()) {
            System.out.println("Found :" + scanner.nextBoolean());
        }/*from ww w. j a  v a2 s .com*/

        // if a boolean is not found, print "Not Found" and the token
        System.out.println("Not Found :" + scanner.next());
    }
    scanner.close();
}
