java - Connection between operator overloading and JVM processing -


i need expert review on statement. encountered statement during recent java interview.

adding operator overloading java have made design more complex without it, , might have lead more complex compiler or slows jvm .

justify ?

  1. from above lines have got 2 questions , how slow down jvm if assume there operator overloading support in java , because overloading being resolved during compile time , , jvm run time perspective (correct me if wrong @ this) .

  2. by making complex compilers can have more freedom of business logic.

a couple of thoughts:

(1) overloading not resolvable @ compile time. subclasses may override methods , not know whether have parent or child class until code executes. don't know how operator overloading have been implemented, have same behaviour.

(2) don't think true. adding operator overloading (essentially syntactic sugar) not allow have more business logic. may express it more succinctly, it's same logic. consider following code, a, b , c instances of same class (ie. they're not scalars). logic same, prefer different expression of it.

c = a.plus(b); c = + b;

html - Outlook 2010 Anchor (url/address/link) -

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
