Why I've got WA test 6?
import java.io.*;
import java.util.*;
public class Trolley{
    public static void main(String args[])throws Exception{
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        int a=0,b=0;
        while(in.ready()){
            StringTokenizer st = new StringTokenizer(in.readLine());
            while(st.hasMoreTokens()){
                String s = st.nextToken("|.,/][';:\"{}!@#$%^&*()_+=- ");
                if(s.equals("tram"))a++;
                else if(s.equals("trolleybus"))b++;
            }
        }
        if(a>b)System.out.println("Tram driver");
        else if(b>a)System.out.println("Trolleybus driver");
        else System.out.println("Bus driver");
    }
}
What is wrong?

try test
trolleybu
out
Bus driver
P.S. My prog works bad on this test

i have the same problem on java

I have AC with string nextToken("`~!@#$%^&*()-_=+\\|[{]};:'\",<.>/?№ "); Test 6 contains '№' symbol.

I rewrited Scanner for that problem.It's very simple :)

class Scanner{

   StreamTokenizer in;

   Scanner(InputStream stream){
      in = new StreamTokenizer(new InputStreamReader(stream));
      in.resetSyntax();
      in.whitespaceChars(0, 127);
      in.ordinaryChars('a','z');//cлово обязано начинаться с символа ordinary. А далее может быть что угодно из wordChar.
      in.wordChars('a','z');
   }

   void asserT(boolean e){
      if (!e){
         throw new Error();
      }
   }

   String nextWord(){
      try{
         in.nextToken();
         if (in.ttype == in.TT_EOF){
            return null;
         }
         asserT(in.ttype == in.TT_WORD);
         return in.sval;
      }catch (IOException e){
         throw new Error();
      }
   }
}

And then called "String word = in.nextWord();"
