Ah, I see. Yes you could monkey something up but it's probably not
worth it....

class Tests

// test();

         Holder h = new Holder();
         h.dogs = 3;
         h.cats = 1;
         String s = instring(
            "I have $dogs dogs and $cats cats and $fish fish.",
                 h );
         System.out.println( s );
     }

     static String instring( String s, Object o )
             throws IllegalArgumentException,
             IllegalAccessException
     {
         for( Field f : o.getClass().getDeclaredFields() )
         {
             s = s.replaceAll( "\\$"+f.getName(), f.get( o ).toString() );
         }
         return s;
     }
}

OUTPUT:
I have 3 dogs and 1 cats and $fish fish.
