This code is part of a servlet running in TC 5.5.12, jre ver 1.5.0.6.

I use this code to break out individual data fields from a line which is structured as "a=11111&b=22222&c=333333333&d=44444&e=5". It is executed for over 2 million data lines per day, so this routine is executed over 10 million times per day. All the fields are short ( < 10 chars) except the 5th one, which can be up to about 40 characters. Is there a more cpu-efficient way of doing this, or is this about as good as it gets?

   private static String getField ( String fieldName, String dataString ) {
       Integer    ii, kk;

       ii = dataString.indexOf( fieldName + "=" );
       if (ii == -1 ) return null;
       kk = dataString.indexOf( "&", ii );
       if ( kk.equals( -1 )) {
           kk = dataString.length();
       }
       return ( dataString.substring( ii + 2, kk ));
   }

TIA!
Dave
