There is hash in java

haha, i wrote this long time ago.......when i started learning java. sucks.

    while((s=in.readLine())!=null){
     System.out.println(s);
     StringTokenizer tokens=new StringTokenizer(s,"|");
     num=tokens.nextToken();
     model=tokens.nextToken();
     brand=tokens.nextToken();
     itemcode=tokens.nextToken();
     file://Postel=tokens.nextToken();
     gifFile=tokens.nextToken();

     Double d=Double.valueOf(tokens.nextToken());
     price=d.doubleValue();//converting string to double
     int tempnum=Integer.parseInt(num);
    }
