      int y = 5;
      for (int i = 0; i < s.length(); i++) {
         char c = s.charAt(i);
         int h = fm.getHeight();
         int w = fm.charWidth(c);
         g.drawRect(x, y, w, h);
         g.drawString(String.valueOf(c), x, y + h);
         x = x + w;
      }
   }
   public static void main(String[] args) {
      JFrame frame = new JFrame();
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
