import java.util.*;

public class Demo {
    public static void main(String[] args) {

        String s = "Hello World! 3 + 3.0 = 6.0 true ";

        // create a new scanner with the specified String Object
        Scanner scanner = new Scanner(s);

        // find the next short token and print it
        // loop for the whole scanner
        while (scanner.hasNext()) {

            // if the next is a short, print found and the short with radix 4
            if (scanner.hasNextShort()) {
                System.out.println("Found :" + scanner.nextShort(4));
            }

            // if no short is found, print "Not Found:" and the token
            System.out.println("Not Found :" + scanner.next());
        }

        // close the scanner
        scanner.close();
    }
}

输出结果为:

Not Found :Hello
Not Found :World!
Found :3
Not Found :+
Not Found :3.0
Not Found :=
Not Found :6.0
Not Found :true
