According to an email I received from Peter Haggar (author of Practical Java: Programming Language Guide). The use of implicit imports have no effect on the performance as it is only used during compile time. It seemed, according to the email (which i unfortunately lost), that the use of implicit vs explicit is mainly a programmer preference. To see a copy of his latest javalive chat session, go to:
http://developer.java.sun.com/developer/community/chat/JavaLive/2001/jl0131. html (Java Developer Connection login required.. free) It might debunk alot of myths including the stupid which is faster while or for loop question. (I've actually done thousands of tests on these 2 because an idiot manager insisted one was faster than the other). BTW. Peter Haggar is a great guy. He answered my email quickly and was very very detailed about it. Not very many authors would take the time to do that. The chat has a link to his email address. -Tim -----Original Message----- From: Mark Galbreath [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 17, 2002 10:29 AM To: [EMAIL PROTECTED] Subject: Class Loader Performance Question Anybody have an idea on the performance hit that might be taken by a high-volume app server running classes with explicit imports rather than wildcard imports? For example, import javax.servlet.http.HttpServletRequest; .... import org.apache.struts.action.Action; .... import org.apache.struts.util.PropertyUtils; .... as opposed to import javax.servlet.http.*; import org.apache.struts.action.*; import org.apache.struts.util.*; Cheers!
