i play robocode (it java programming game). want change method public void onscannedrobot (scannedrobotevent e) { } to public int onscannedrobot(scannedrobotevent e){ } so can adapt robot more if scanned true or false. i heard possible overriding method. tryed it: i wrote: public void onscannedrobot(scannedrobotevent e) { public int onscannedrobot(scannedrobotevent e) { return 1; } } but won't work this won't work because return type of overriden method should same or subtype of return type declared in original method. @ link overriding , overloading

i want show using php how many 502 errors server(nginx) have in last 24 hours. couldn't find simple way thanks! there no single way this. better solution, proxy server accepting requests local ip address. work (not tested) the simple solution: grep '502' access.log | wc -l the complex solution: http { upstream error_logger { server 127.0.0.1:80 } } server { error_page 502 /502.html location / { # config here } location /502.html { internal; proxy_pass http://error_logger/502.php; } } the script (502.php); <?php if($_server['remote_addr'] != '127.0.0.1') die(); // logging here

i read several posts concurrency problems i'm still unsure something. can when using synchronized, volatile functionality free, because when lock on object released, next thread reads modified object. volatile, value of object reflected other threads. when use synchronized, there no possibility reflect due lock on object. when lock released, thread may access it. don't have care reflecting value other threads. understand right? [update] example prints 1 2 3 4 5 6 7 8 9 without volatile. package main; public class counter { public static long count = 0; } public class usecounter implements runnable { public void increment() { synchronized (this) { counter.count++; system.out.print(counter.count + " "); } } @override public void run() { increment(); increment(); increment(); } } public class datarace { public static void main(string args[]) ...

i've got winform app 3 layer architecture ui bll (business logic/layer) dal (data access layer) the dal contains factory instantiate proxies used communicate various apis, require credentials of private methods when app starts, 1 or more proxies initialised singletons (1 per api). references singleton kept within app @ ui , bll levels (and maybedal later). the user can choose @ time modify api credentials via ui. in case, want initialise new instances of the singletons, , make sure correct instances used everywhere (ui, bll, dal) what did far is: notify factory of credentials changes, singletons reinitialised used event aggregator pattern in ui, components holding references singleton notified of credential changes , call proxy factory fresh instance however, wanted use event aggregator pattern in ui. question is: how notify objects in bll/dal of change? a solution never hold instances , call factory, there way of doing want properly? edit : have class...

can 1 time reason behind assigning default values data members , not local variables ? there specific reason ? example : class { b b; public void f(){ int a; } in above class b initialized null, compiler throws , error saying variable inside f() not initialized. i (as always) practical reason. can initialize object @ 1 point , use time later - have have mechanism ensure initialized default value in case cannot set them immediately. local object on other hand used after declared - can safely assume programmer able initiate them target value, , should encouraged. bottom line - practical reasons, encouraging practices prevent errors, nothing technical limitations.

how can access function name inside function? // parasitic inheritance var ns.parent.child = function() { var parent = new ns.parent(); parent.newfunc = function() { } return parent; } var ns.parent = function() { // @ point, want know child called parent // ie } var obj = new ns.parent.child(); in es5, best thing is: function functionname(fun) { var ret = fun.tostring(); ret = ret.substr('function '.length); ret = ret.substr(0, ret.indexof('(')); return ret; } using function.caller non-standard , arguments.callee forbidden in strict mode. edit: nus's regex based answer below achieves same thing, has better performance! in es6, can use myfunction.name . note: beware js minifiers might throw away function names, compress better; may need tweak settings avoid that.
