newbie here.. i'm wondering best practice in following case: i use mvc-pattern. controller-class needs call model-class perform procedure. procedure has 4 steps. in 3 first steps, if goes wrong, model produce list of strings, controller must ensure displayed user, in addition error message. in last step, model produce map, again controller must ensure showed user. in last step, timeout occur.. what best way handle this? i have made 2 rough drafts of suggestions below. alternative 1: public class model{ public list<string> step1(){ // return empty list if ok, fill list otherwise } public list<string> step2(){ // return empty list if ok, fill list otherwise} public map<string, string> step3(){ // return empty list if ok, fill list otherwise} } public class controller{ model mymodel; public void doprocedure(){ list<string> list = mymodel.step1(); if(list.size() != 0){ str

i created note web app allows user create several notes , navigate between them using various tabs on left. now want these notes save in local storage added following code: $(document).ready(function() { $(window).unload(savesettings); loadsettings(); }); function savesettings() { localstorage.notes = $('#notes').html(); } function loadsettings() { $('#notes').html(localstorage.notes); } } it works in degree. meaning whole div saved in cache reason when reload page can see different tabs not text wrote. whole point save notes it's problem if can't see text wrote. i unfortunately not knowledgeable on javascript & jquery, have no idea do. i believe smarter save each tabs , textarea individually in cache instead of whole div don't know how that. if can me or @ least guide me, appreciated. the "value" of <textarea> field apparently not become part of innerhtml of el

i did searches oracle sql outer joins see whether there shotcut (like think in mysql can *= b believe, outer join). found 1 thing looked promising didn't work. trying find shortcut because can never remember outer join syntax. have time. take example: select l.*, r.* database.login l left outer join database.relation r on l.user_id = r.user_id , r.user_id null several values of r.user_id null expected. tried read somewhere: select l.*, r.* database.login l, database.relation r l.user_id = +r.user_id but did not select rows database.relation did not have user_id matching database.login. so have type whole syntax? trying entry in login not in relation. i suppose use following: u.user_id not in select user_id database.relation if necessary you can this: select l.*, r.* database.login l, database.relation r l.user_id = r.user_id (+) for left outer join , select l.*, r.* database.login l, database.relation r l.user_id (+) = r.u

i have multiple divs same class name, once 1 clicked don't want function happen again if same class clicked again. $('.js-item').one( "click", function() { console.log('clicked once'); // once if div same class clicked again }); is there way .one() happen once on classes? because @ moment applies once each time individual div class name clicked. i need these divs have same class name. you can call off() on classes after executing logic: $('.js-item').one("click", function() { console.log('clicked once'); // once if div same class clicked again $('.js-item').off('click'); }); <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="js-item">click me!</div> <div class="js-item">click me!</div> <div class="js-item">click me!</div> <

i have text file room numbers in school. have code asks room number of student's class. kb user input scanner , roomnos text file scanner. code: string room = null; boolean invalid = true; while(invalid) { system.out.println("what room number of class?"); room = kb.nextline(); while(roomnos.hasnext()) { string roomno = roomnos.nextline(); if(room.equals(roomno)) invalid = false; } if(invalid == true) { system.out.println("the room number you've given invalid."); } } the code works if first room number given user valid. however, if user inputs invalid room number, loop not stop, is, says room number invalid , asks room number again , again, if room number valid. think hasnext() in nested while loop not restart , go beginning of file , hence, cannot search room number during next loops of bigger while loop. whatever problem is, how can fix it? your check invalid input happens

currently using recursive invalidate() calls , don't know if code run at fixed rate in every phone . below can see code here. handler approach better , reliable one? how can make view update speed fixed in every phone? @override protected void ondraw(canvas canvas) { super.ondraw(canvas); if(action){ checkcollisiondetection(); rotateangle = rotatereverse ? rotateangle - levelrotatespeeds[level-1] : rotateangle + levelrotatespeeds[level-1]; canvas.rotate(rotateangle,coordinateutils.centerx,coordinateutils.centery); invalidate(); //this recursive approach }else canvas.rotate(rotateangle,coordinateutils.centerx,coordinateutils.centery); canvas.drawroundrect(rect,markerroundsize,markerroundsize,paint); }
