        // setting cursor of iterator
        cel.setOffset(2);
        cel.next();
  
        // display the result
        System.out.println(
            "current offset before calling reset() "
            + cel.getOffset());
  
        // reset the cursor to the
        // beginning of the string
        // using reset() method
        cel.reset();
  
        // display the result
        System.out.println(
            "\ncurrent offset after calling reset() "
            + cel.getOffset());
    }
}
