Only a little comment :-)
When I have to make many string comparisons just like in this code fragment, I prefer
using the intern() method of the String class.
The code changes to:
String s = request.getParameter("collection");
s = s.intern();
// Now comparisons can be made through ==
if (s == "scopus") {
...
}
else if (s == "securetrak") {
...
}
else ...
String comparisons are expensive. If the number of comparisons is large enough, the
cost of the intern() call becomes insignificant.
Of course, I am speaking about more than two comparisons. Anybody have made some
tests? I have never had time enough. I use this when I have to do more that ten
comparisons, but I suppose it can provide benefits with less comparisons.
