i have question regarding using method in main class, here code race class: import java.util.arraylist; public class race { private arraylist<car>cars; public race(){ cars = new arraylist<car>(); } public void addcars(car car){ cars.add(car); } } the above have done make arraylist cars ready put in using main method in class: public class test { public static void main(string[] args) { car toyota = new car("toyota",1.0,1.0,2.0,2.0); cars.addcars(toyota); } } however, has error in last line, shows "cars cannot resolved",i not sure how should fix it, maybe writing getter method in race class? create instance of race , call addcars race race = new race(); race.addcars(toyota);

is there css selector selecting parent div if directly contains select inside ? example code: <div class="top_level"> <input type="radio"></input> </div> <div class="top_level"> <input type="text"></input> </div> <div class="top_level"> <select name="namehere"> <option>...</option> <option>...</option> <option>...</option> </select> </div> suppose want select third 3rd top_level class div, since contains select directly inside it, how ? i did try search around answer, couldn't find any. have been lot easier if parent selection possible in css. if you're using jquery, can use :has : $('div.top_level:has(select)') if you're using css, answer simple : no, don't have similar select parent.

i did: var element = document.getelementbyid('myelement'); now want do: element.myfunction(); but have no idea how element within function. how do this? function myfunction() { // element here? } you can add custom function prototype of htmlelement objects this: htmlelement.prototype.customfunc = function(){ // within function, 'this' refer // element called on }; this means element have access customfunc function method. example: htmlelement.prototype.customfunc = function(){ console.log(this.id); }; // assuming html contains #myelement , #anotherelem: document.getelementbyid('myelement').customfunc(); // displays 'myelement' document.getelementbyid('anotherelem').customfunc(); // displays 'anotherelem' obviously, careful naming of function, don't want overwrite pre-existing methods or properties.

i created form using formbuilder in symfony. add basic styling form inputs using external stylesheet , referencing tag id. form renders correctly , processes information correctly. however, outputs unwanted unordered list list item containing following text: this form should not contain fields. i having hard time getting rid of notice. wondering if can me understand why being rendered form , how remove it? many in advance! controller $form = $this->createformbuilder($search) ->add('searchinput', 'text', array('label'=>false, 'required' =>false)) ->add('search', 'submit') ->getform(); $form->handlerequest($request); twig output (form outputted , processed correctly this form should not contain fields. rendered html <form method="post" action=""> <div id="form"> <ul> <li>this form should not conta

so... have list of input boxes in form... no labels, placeholder texts. lets have text input field email... and value of text ruby@rails.com i display: (email) after string...

i'm working on project requires working gigabytes of scientific data sets. data sets in form of large arrays (30,000 elements) of integers , floating point numbers. problem here large fit memory, need on disk solution storing , working them. make problem more fun, restricted using 32-bit architecture (as work) , need try maximize performance solution. so far, i've worked hdf5, worked okay, found little complicated work with. so, thought next best thing try nosql database, couldn't find way store arrays in database short of casting them character arrays , storing them that, caused lot of bad pointer headaches. so, i'd know guys recommend. maybe have less painful way of working hdf5 while @ same time maximizing performance. or maybe know of nosql database works storing type of data. or maybe i'm going in totally wrong direction , you'd smack sense me. anyway, i'd appreciate words of wisdom guys can offer me :) assuming data sets large enough

i use http binding @ services. read net.tcp binding works faster, not quite sure on when should use it? best practice, there drawbacks? thanks the msdn page nettcpbinding says best the default configuration nettcpbinding faster configuration provided wshttpbinding, intended wcf-to-wcf communication. so nettcpbinding use when have .net wcf client , .net wcf server, if need support clients not written in .net wcf (for example publishing public service , don't know language client written in) need use httpbinding instead. this page has quick summary of each type of binding , when should used. basichttpbinding - binding suitable communicating ws-basic profile conformant web services, example, asp.net web services (asmx)-based services. binding uses http transport , text/xml default message encoding. wshttpbinding - secure , interoperable binding suitable non-duplex service contracts. ws2007httpbinding - secure , interoperable binding pr

i'm having problems solving why jquery being ignored. below jquery: $(document).ready(function() { var $root = $('html, body '); $('a').click(function(e) { var href = $.attr(this, 'href'); $root.animate({ scrolltop: $(href).offset.top }, 500, function () { window.location.hash = href; }); return false; }); this jquery trying nicely scroll part of page works if use .offset('top') throws out error : uncaught typeerror: cannot use 'in' operator search 'using' in top which has made jquery jump instead of scroll nicely. the rest of jquery code: // responsive menu $(function() { var pull = $('#pull'); menu = $('nav ul'); menuheight = menu.height(); $(pull).on('click', function(e) { e.preventdefault(); menu.slidetoggle(); }); $(window).resize(function(){ var w = $(window).width();

i have confusion compilation , interpretation , way jit works. know source code or java program gets compiled java byte code loaded onto jvm either interprets bytecode native machine code or uses jit. i going through interpreter doc , understood interpreter analyses each statement on every request , converts native code leading slower performance. and read jit dynamic translation , stores native code on cache used subsequent requests. what wanted understand how jit works? whenever first request made application converts part of byte code machine code, stores on cache , uses it.. process? if then, every first request slower needs translation of bytecode machine code? please explain in detail. depends on implementation, @ least in java, jit done "hotspots", i.e. used code. if jvm finds out method has been called more x times compile native code. meaning, have call few times first, , gets faster after that. also, jit results kept in-memory, not saved disk

i need disconnect sender , return receiver's main ("ready cast" screen). receiver decides when , how (e.g. 10 mins idling after media playback paused) i've tried stop receiver explicitly receiver.stop() and disconnecting connection service cs = receiver.getconnectionservice() cs.disconnect() that didn't work wanted, doesn't return main screen , senders still see ongoing cast session so how can force disconnecting on receiver? receiver api page seems describing these 2 methods. you shouldn't call receiver.stop() , nor calling cs.disconnect(); instead try using window.close() .
