according this table of java operator precedence , associativity , member access has higher precedence new operator. however, given class myclass , non-static member function myfunction , following line of code valid: new myclass().myfunction(); if . evaluated before new , how can line executed? in other words, why aren't parentheses required? (new myclass()).myfunction(); my guess since () shares precedence . , myclass() evaluated first, , compiler knows before evaluating new keyword myclass constructor 0 parameters being called. however, still seems imply first line should identical new (myclass().myfunction()); , not case. this because of how grammar of java language defined. precedence of operators comes play when same lexical sequence parsed in 2 different ways not case. why? because allocation defined in: primary: ... new creator while method call defined in: selector: . identifier [arguments] ... and both used here: expr

i've 2 lists, in 1 store information of few celebrities, , list store awards information pertaining these actors. the problem trying solve combine these 2 lists 1 award information becomes attribute list of awards. , yes simple achieve. for actor in actor_info: award in award_list: if actor['personid'] == award['personid']: if not actor.get('awards', false): actor.update({'awards':[]}) actor['awards'].append(award) but if observe code above, iterates len(actor_info) * len(award_list) times not elegant solution. there other perspective problem, execution cycles less. note: to explain problem more clearly, i've described below data structure using. each element in actor_info , award_info list dictionary. actor_info = [] d = {} d['personid'] = 1210 d['firstname'] = 'robert , jr' d['lastname'] = 'downey' d['birthplace'] = &#

how can optimize next() , hasnext() methods in following generator produces combinations of bounded multiset? (i posted c++ java because code c++-compatible , has no java-specific elements not convert directly c++. the specific areas of algorithm problematic entire hasnext() method may unnecessarily complicated, , line: if( current[xslot] > 0 ) aiitemsused[current[xslot]]--; which has if-statement think removed somehow. had earlier version of algorithm had of backtracking before return statement , consequently had simpler hasnext() test, not version work. the background of algorithm is difficult find. example, in knuth 7.2.1.3 merely says can done (and gives exercise prove algorithm possible), not give algorithm. likewise, have half dozen advanced texts on combinatorics (including papadimitriou , kreher/stimson) , none of them give algorithm generating combinations of multiset. kreher leaves "exercise reader". anyway, if can improve algorithm above or provi

so in cases better code readability use div#parent div.someclass a , can div.someclass a . version better , faster? it's important when using jquery consider selectors have converted native browser functions @ end of day. means should try use id or tag based selectors whenever possible. recommend using $("div#parent").find("div.someclass a") better performance this gives better performance since use optimized tag/id selector parent, , slower class based selector applied more limited set since applied descendants of specified parent.

i have 2d array store in redis , see 2 solutions: storing json string or storing 1 hash per line. way better? i faced same question when designing application. opted on side of simplicity. i'm going assume 2d array of data represents database row. json encode , store using set . allows me use mget , mset when want handle multiple objects using 1 redis command. if data gets updated in database, del key. me easier trying update redis hash. hashes in redis has advantages. take less memory because of "ziplist" encoding redis uses. can avoid serialization well, pretty significant apps. here's sample use case hash me. let's want username given user id. hget user.usernames 1234 . give me username user id 1234. if there miss, query db , set , since data never changes, never expire hash. allows quick common piece of data rather pulling entire user, unserialize, , return needed field. for prospective massive lookup table, use algorithm pur
