this question has answer here: understanding strange java hash function 6 answers static int hash(int h) { // function ensures hashcodes differ // constant multiples @ each bit position have bounded // number of collisions (approximately 8 @ default load factor). h ^= (h >>> 20) ^ (h >>> 12); return h ^ (h >>> 7) ^ (h >>> 4); } could tell me why hash method designned this?what benefit? if see open jdk source , this method have comments... /** * applies supplemental hash function given hashcode, * defends against poor quality hash functions. critical * because hashmap uses power-of-two length hash tables, * otherwise encounter collisions hashcodes not differ * in lower bits. note: null keys map hash 0, index 0. */

the problem is: have page1.jsp submitted , forwarded page2.jsp. problem forwarded output should content in page2.jsp, instead of showing me content page1.jsp , content page2.jsp i'm using requestdispatcher.forward(string) don know why happening ps: i'm using je 1.4 well seems have got method signature incorrect . per javaee 1.4 api : public void forward(servletrequest request,servletresponse response) throws servletexception, java.io.ioexception hence code should : requestdispatcher dispatcher = request.getrequestdispatcher("page2.jsp); dispatcher.forward( request, response ); better , can use <jsp:forward> standard action. the jsp contains action stops processing, clears buffer, , forwards request target resource. note calling jsp should not write response prior action. suggested reading: how avoid java code in jsp-files?

i need write functions returning ranges within array (you may, if like, assume they're specified starting position , length). can't return tuple, need return other type (and maybe it's idea anyway). now, i'd return that's both (somewhat) standard , not incur performance penalty due vtables, convoluted ctors etc. the options come mind are: std::pair<unsigned> (or std::pair<size_t> ). a struct wrapping 2 unsigned s (or size_t 's). rolling own range class, sugar-coating utility methods. i tried looking proper range class, couldn't find one. it's kind of strange nothing in standard library/stl uses class ranges. are there better alternatives? , if there aren't, of above recommend? the main reason why hard answer it's not clear kinds of situations range used. don't know yet exactly. in situations recommend creating own class, because keeps flexible. can add member functions , nested typedefs needed. if in
