I don't think this materially affects my argument tho', because the only time where the performance difference between, foo == "literal" and, foo.equals("literal") is going to be significant is where there are long chains of comparisons, ie., if(foo == "elem1") // do stuff for elem1 else if(foo == "elem2") // do stuff for elem2 // ... repeat many times ... else if (foo == "elemn") // do stuff for elemn where it'd be a far better idea (both from performance and software design POVs) to do something like, ElementHandler handler = (ElementHandler)someTable.lookup(foo); handler.doStuffForElement(); Cheers, Miles -- Miles Sabin Cromwell Media Internet Systems Architect 5/6 Glenthorne Mews +44 (0)20 8817 4030 London, W6 0LJ, England msabin@c... http://www.cromwellmedia.com/ xml-dev: A list for W3C XML Developers.
