i have 1 class named sample used in code. class sample{ . . object somemethod(){ return someobject; } . . } i call : object ob = new sample().somemethod(); i want know there advantage if create anonymous object of class( new sample() ) , call require method if don't have further use of object. benefits? i assume asking code posted contrasted following: sample s = new sample(); s.somemethod(); (where explicitly assign new sample() local variable). there's no significant performance or memory benefit 1 way or another. if store reference in local variable , invoke method, suppose there may (extremely) small performance penalty storing reference. however, suspect many compilers notice variable dead once method called , optimize away assignment. jit compiler might finish job. we're talking few cpu cycles @ most.

running test-connection ip address takes considerably longer running same command server's hostname. however; if add -quiet parameter performance same (ip fraction faster, may expect). using measure-command anomaly not show up; presumably quirk of output not being displayed. the below code more accurately reflects anomaly seen: $begin=(get-date).ticks;test-connection '123.45.67.89'; $a=((get-date).ticks - $begin) $begin=(get-date).ticks;test-connection 'myhostname'; $b=((get-date).ticks - $begin) $a-$b colleagues have reproduced same issue on machines. question: aware of may cause this? i.e. suspect it's bug (and have reported such), implies there's clever going on powershell may work differently depending on whether output displayed or not / causing quantum-like effect; it's not running commands given in order, doing (de)optimisation under covers. my environment os: ms windows 7 pro sp1 $psversioninfo : name ...

this question understanding interfaces in java. here simple example of implementing interfaces in java. interface parenta { void display(); } interface parentb { int display(); } class child implements parenta, parentb { @override public void display() { system.err.println("child parenta"); } //error : return type incompatible parentb.display() //so added method int return type @override public int display() { system.err.println("child parentb"); } } this case can happen in large java application 2 interface can have method same name. thought since return type different jvm know interface's method overriding. what best explanation this? situation make sense? thanks in advance because method same signature not allowed, confuses compiler detect exact override-equivalent method declared once. jls (§8.4.2) 2 methods or constructors, m , n, have same signature if have, ...
