问题 I have an ArrayList which having many objects. I want to do sum of values of the same property name. Examples Data in Array List which is Objects of ProfitAndLossDataDO "Michel" , 5000 "Alex" , 5000 "Edvin" , 4000 "Sosha" , 3000 "Michel" , 2000 "Alex" , 3000 And the Result Would be (Sum of values when person are same)- "Michel" ,7000 "Alex" , 8000 "Edvin" , 4000 "Sosha" , 3000 The Logic class ProfitAndLossDataDO public class ProfitAndLossDataDO { String ledgerName; double ledgerAmount; public

问题 I looked at the template definition and the parameters appear to want iterators across a range and a predicate. I passed in a vector.begin(), ...end(), and a std::string predicate but still get many compile time errors related a host of boost library items. Can I see a clear example of the use of boost::algorithm::contains please? 回答1: It's fairly simple, I guess you are passing iterators when you should be passing containers. std::string s = "fishing"; std::cout << boost::algorithm::contains

问题 I want to know is there a generic way to write code to judge whether a slice contains an element, I find it will frequently useful since there is a lot of logic to fist judge whether specific elem is already in a slice and then decide what to do next. But there seemed not a built-in method for that(For God's sake, why?) I try to use interface{} to do that like: func sliceContains(slice []interface{}, elem interface{}) bool { for _, item := range slice { if item == elem { return true } }

问题 Was hoping to find out if there is an easy way to check if a list only contains certain list values. For example if I have a list of int that could randomly contain distinct ints 1-10 (ie 1,3,7 or 2,3,4,6,8,9) and I want to check if the list only contains int 1 and/or 5. 1 or 5 or 1,5 would return true and anything else would return false. This is actually for an MVC project and is a list of strings. Based on conditions I build a string list and want to check if 1 or both of 2 certain strings

问题 well, I am more of a PHP person, and my JS skills are close to none when it comes to any JS other than simple design related operations , so excuse me if I am asking the obvious . the following operations would be a breeze in PHP (and might also be in JS - but I am fighting with unfamiliar syntax here ...) It is some sort of input validation var ar = ["BRS201103-0783-CT-S", "MAGIC WORD", "magic", "Words", "Magic-Word"]; jQuery(document).ready(function() { jQuery("form#searchreport").submit

问题 How can I check in the following json that at least one element in the array names has a property nickName with the value Ginny ? { "names": [ { "firstName": "Hermione", "lastName": "Granger" }, { "firstName": "Harry", "lastName": "Potter" }, { "firstName": "Ron", "lastName": "Weasley" }, { "firstName": "Ginevra", "lastName": "Weasley", "nickName": "Ginny" } ] } Currently I'm using the draft-06 version (FAQ here). This is my NOT WORKING schema: { "$schema": "http://json-schema.org/draft-06

问题 I am a newcomer to XPath. I am looking for a way to get all elements whose tag name contains a particular string. For example, if I have XML like below, I want to get all the elements whose tag name contains the word 'Name'. i.e., I want to fetch the following elements: <SquareName> , <RectangleName> , and <ParallelogramName> . I tried some combinations of name() , contains() etc., but it did not work. Please suggest. <Objects> <Four-Sided> <Square> <SquareName>ABCD</SquareName> <Length>4<

问题 I'm constructing a linq query that will check is a string in the DB contains any of the strings in a list of strings. Something like. query = query.Where(x => x.tags .Contains(--any of the items in my list of strings--)); I'd also like to know how many of the items in the list were matched. Any help would be appreciated. Update: I should have mentioned that tags is a string not a list. And I am adding on a couple more wheres that are not related to tags before the query actually runs. This is
