code here: $obj instance of class user.i calling methods not showing output <?php class user{ public $name; public $age; public function _ _construct($name, $age){ $this->name=$name; $this->age=$age; } public function sayhello(){ echo("hiiiii".$this->name."!!!"); } public function sayage(){ $a=time()-strtotime($this->age); echo " hello age is".floor($a/(365*30*60*60)); } } $obj = new user('xyz','16 july 1980'); $obj->sayhello(); $obj->sayage(); ?> just remove $var $obj. call $obj <?php class user{ public $name; public $age; public function __construct($name, $age){ $this->name=$name; $this->age=$age; } public function sayhello(){ echo("hiiiii".$this->name."!!!"); } public function sayage(){ $a=time()-strtotime($this->age); echo " hello age is".floor($a/(365*30*60*60)); } } $obj = new user('xyz','16...

i have defined set of actions , trying add multiple actors. here's code: parallelaction actions = new parallelaction(); rotatebyaction rotateaction = new rotatebyaction(); rotateaction.setamount(rotationamount); scalebyaction scaleaction = new scalebyaction(); scaleaction.setamount(-0.01f); delayaction delayaction = new delayaction(); delayaction.setduration(0.05f); repeataction raction = new repeataction(); raction.setcount(100); actions.addaction(rotateaction); actions.addaction(scaleaction); actions.addaction(delayaction); raction.setaction(actions); for(monster mon : mons) // mons arraylist of type monster (which extends image) mon.addaction(raction); but above logic adds action last actor in arraylist. why can't use same action multiple actors? need define many actions actors, or there other way it? i looked upon pool here https://...

does know how check list contain objects or strings? in javascript arrays untyped, meaning: nothing take care of in it, if don't yourself. since array composite structure addressed integer value, can check every address exact type stored inside. if array created else. however, array type if find objects, strings , int's in it? other options: create own structure specify type on creation , throw error in add(item) method if items type violated create own structure in add(item) take care of type , write in property of structure

any command know remote repository connected to? if browse directory contains .git folder. can run command know remote repository .git folder mapped ? there no 1:1 local:remote mapping git repos. every repo can have several remotes, or none @ all. you can use git remote -v list of remotes in local repo's config. note these aliases convenience, , can directly fetch , push remote repos using urls.

i not sure means: virtual ~optimizer() { jnienv *env = getjnienv(); env->deleteglobalref(mjavaoptimizer); mjavaoptimizer = 0; } what confuses me delete global reference , set 0. isn't deleting enough? why assignment 0 part? thanks in code, being in c++ destructor, has no practical use. it's programming pattern. in many contexts, variable accessible (visible) before or after holds valid value. during times, preferable hold known value chosen value can tested (a sentinel value) and/or misuse reliably caught in defined way (e.g., null pointer vs bad pointer). setting variable standard invalid value serves comment operation has invalidated previous value, might not obvious reading of immediate code.
