say want 'of' typed in input user i making app, not finishing off in dumb output screen (this example) import java.util.*; scanner input = new scanner(system.in); string text = input.nextline(); int check = 0; for(int = 0; < text.length(); i++;){ if(text.substring(i, + 2) .equals("of")){ check = 0; } } if user enters abofd , surely recognises of @ position @ 2-4. when i value 4 checks position 4-6, position 6 not present not present gives error. know thinking me set i < text.length() - 1 @ line 5, original code needs run until end! it good idea validate input coming user, overcomplicating things! worse, wrote down outright wrong code: string text = input.nextline(); int check = 0; for(int = 0; < text.length(); i++;){ if(text.substring(i, + 2) .equals("of")){ the above can't work! see, i iterates 0 text length. using i+2 substring text. (so: hello first arrayindexoutofboundsexception). i...

i have simple treeview, when click on treeview item load text file here code: private async void notestreeview_onselecteditemchanged(object sender, routedpropertychangedeventargs<object> e) { var clickedmodel = e.newvalue treefileitem; if (clickedmodel != null && file.exists(clickedmodel.filepath)) { _viewmodel.noteloadinginprogress = true; using (var reader = file.opentext(clickedmodel.filepath)) { var filecontent = await reader.readtoendasync(); _viewmodel.activenote = filecontent; } _viewmodel.noteloadinginprogress = false; } } this works, when click on treeview item ui frozen, until file read complete. why such behavior? have other async methods in code , don't block ui. edit: seems issue not in reading file, in setting large amount of text textbox.text properti via databinding, though setting directly take lot of time , make ui freeze the ui frozen, until file...

insert :: eq(a) => -> -> [a] -> [a] insert m n [] = [] insert m n (x:xs) | m==x = n : x : insert m n xs | otherwise = x : insert m n xs the insert function above working function inserts value n list before instances of value m . i need writing interspace function inserts value n between values m , q in list. have far: interspace :: eq(a) => -> -> a->[a] -> [a] interspace m n q[] = [] interspace m n q (x:xs)| m==x && q==(head xs) = n: x : insert m n (headxs)++interspace m n q (xs) | otherwise = x : interspace m n q xs since adding values front of list, insert function unnecessary.

i using statement similar union results 2 similar tables. select sale_time, nullif(sale_time, '0000-00-00') 'nullif_sale_time' tblcompletedsales union select sale_time, nullif(sale_time, '0000-00-00') 'nullif_sale_time' tblopensales; sale_time timestamp field on both tables. instead of getting full date, in nullif_sale_time, truncated version. in other words, if sale_time '2015-08-12 09:33:46' nullif_sale_time '2015-0'. true records both tblcompletedsales , tblopensales. example: sale_time nullif_sale_time 2015-06-15 10:44:44 2015-0 if run either statement without union both work expected. has worked expected until today. happening on local machine remote server. what cause this? there missing? edit: here fiddle shows same thing.

my rails app hosted on heroku postgress database. model i'm asking user chose day , time, combine date before saving model: def create_timestamp self.date = day.to_datetime + time.seconds_since_midnight.seconds end when chose instance today @ 20:50:00 , store in database, record looks this: <report id: 1, account_id: 1, date: "2016-11-05 20:50:00", description: "test", created_at: "2016-11-05 19:50:57", updated_at: "2016-11-05 19:50:57", deleted_at: nil, user_id: 1, report_category_id: 2, time: "2000-01-01 20:50:00", day: "2016-11-05"> as might notice, created_at date different, because it's in different timezone. while created_at stored in utc +0000, custom date, uses local timezone cet +0100. so when type in console: report.find(1).date , returns 2016-11-05 21:50:00 +0100. how can store correct date in initial set, or make database return correct timezone when querying? thanks ...

i trying make simple clojure macro applies inputted function twice: (f (f args)) , (e.g (inc (inc 4)) => 6 ) the problem is, when run below code using (reapply-function '(inc 4)) , nil . doesn't make sense me since can print out both value of f , result inc , 5 . there must simple thing i'm missing. can see issue? (defmacro reapply-function [args] (list 'let ['f (list 'first (list 'quote args)) 'result args] (list 'f 'result))) initial note this answer provided assuming you're trying learn use macros own sake. agree @thumbnail's answer : don't use macros except when absolutely, positively cannot avoid -- , not 1 of times. shorter implementation consider: (defmacro reapply-function [[func & rest]] `(~func (~func ~@rest))) macroexpand demonstrates how works: user=> (macroexpand '(reapply-function (inc 4))) (inc (inc 4)) ...and functions in repl: user=> (rea...

i learning design pattern in javascript, , i'm going use module pattern. i'm puzzled 2 things. 1 - if create plugin, can use module pattern, , have private , public methods/variables. if have full javascript file, don't need private , public methods, since 1 part of program has nothing part. what's point of private , public methods? 2 - since javascript file long, should have nested module's? how should go full file of javascript? (1) when javascript files loaded, scripts in files in 1 file. script in 1 file can access (read, update, delete) global variables in other files. there lot of questions on this, can search those. of course, "one part of program has nothing part", in case in team many members, each works on part of system (or in cases, file). then, there chance 1 person accidentally changes variables created person. kinds of error quite easy detect. if can modularize script, can avoid kinds of error altogether. (2) you ca...

i have piece of code: def validate_index index # change sizeerror raise argumenterror, "size of index (#{index.size}) not matches"\ "size of vector (#{size})" if size != index.size end on this, rubocop gives offence: style/multilineifmodifier: favor normal if-statement on modifier clause in multiline statement. i modified code this: def validate_index index # change sizeerror if size != index.size raise argumenterror, "size of index (#{index.size}) not matches"\ "size of vector (#{size})" end end but gives offence: style/guardclause: use guard clause instead of wrapping code inside conditional expression. am doing wrong or bug? rubocop wants write this: def validate_index index # change sizeerror return if size == index.size raise argumenterror, "size of index (#{index.size}) not matches"\ "size of vector (#{size})" end it if want go route. either way, rubocop re...

i have console application made of c# it allows user paste text following aaaaa bbbbb ccccc i know console.readline() wont take it, used console.in.readtoend() string input = console.in.readtoend(); list<string> inputlist = input.split('\n').tolist(); i need parse input text line line above code works, after pasting, in order conintue, user has hit enter once, hit ctrl+z hit enter again. im wondering if there better way requires hit enter key once any suggestions? thanks in console if paste block of lines not executed immediately. if paste aaaa bbbb cccc nothing happens. once hit enter, read method starts doing it's job. , readline() returns after every new line. way it, , imo it's easiest way: list<string> lines = new list<string>(); string line; while ((line = console.readline()) != null) { // either here each line separately or lines.add(line); } // of lines here my first stacko...

i'm stuck following problem springmvc, thymeleaf , javascript. 1) server-side: under circumstances add flash redirect attribute in controller before redirecting page. redirectattributes.addflashattribute("mycondition", true); 2) client-side: in case attribute exists, want javascript function execute additional code. window.onload = function() { ... if([[${mycondition}]]) { //do } } this works fine after redirect, on first enter redirect attribute not exist, results in following javascript code being rendered: window.onload = function() { if() { //do } } this code not valid , therefore produces javascript error. i'm not sure how check javascript if redirect attribute exists? has run similar problem before? can try following code , let me know if works declare variable mycondition var mycondition = [[${mycondition}]]; if(mycondition) { //do } hope helps
