Checking if long is in array

由 ▼魔方 西西 提交于 2019-12-14 02:14:35
问题 I need to make sure that a certain long value isn't in an array. But for some reason, this isn't working... !d.toString().contains(sq.toString()); I am sure I am getting something really backwards... but I can't figure out what! 回答1: Try !Arrays.asList(d).contains(sq); 回答2: Look at the static methods in java.util.Arrays. Your array will need to be sorted for the binarySearch() to work. 来源： https://stackoverflow.com/questions/5010044/checking-if-long-is-in-array

问题 From the CakePHP manual: Let's say you had a belongsTo relationship between Posts and Authors. Let's say you wanted to find all the posts that contained a certain keyword ("magic") or were created in the past two weeks, but you want to restrict your search to posts written by Bob: array ( "Author.name" => "Bob", "OR" => array ( "Post.title LIKE" => "%magic%", "Post.created >" => date('Y-m-d', strtotime("-2 weeks")) ) ) However, its not working for me. I've got Scrapes belongsTo Vargroup, and

问题 I have an array composed of an X number of 2DPoints, and my goal is to do a boolean operation that could check if that array has the specified 2DPoint. Something like this: Point2D.Double arrayPoints[] = new Point2D.Double[numberOfPoints]; Point2D.Double pointPVariable = new Point2D.Double(positionXVariable,positionYVariable); arrayPoints[variableNumber] = pointPVariable; if(arrayPoints has the Point2D(2.45,6.52)){ do this } How can I do that boolean operation?? Thank you very much! 回答1:

See if String Contains An Element in an Array

问题 I am trying to go through an array of Operators to see if one of the operators is located in the String. For example: String[] OPERATORS = { "<", "<=", ... }; String line = "a <= b < c "; How would I go about going through a loop that checks to see if an operator is in the string? Also, say my method found that "<" is located in the string at " < = " However, I am looking for the actual string " <= ". How would I go about accounting for that? 回答1: I would use a regex instead of having array

Java: How to check if a string is a part of any LinkedList element?

由 会有一股神秘感。 提交于 2019-12-08 06:09:08
问题 Okay so I have a LinkedList, and I have a String. I want to check if the String is contained within any of the LinkedList elements. For example: String a = "apple"; String listelement = "a bunch of apples"; LinkedList list = new LinkedList(); list.add(listelement); if(list.containsany(a){ System.out.println("Hooray!"); } Would result in printing "Hooray!" Obviously list.containsany isn't a real LinkedList method, I'm just using it for this purpose. So how can I simulate my example? Thanks 回答1

I want to get the id in class like... <div class="main demo id_111 test"></div> <div class="main demo test id_222 test demo"></div> <div class="id_3 main demo test test demo"></div> Result must be 111 , 222 and 3 So I code like this var id = $(".main").attr("class"); var id = id.split("id_"); var id = id[1].split(" "); var id = id[0]; $("body").append(id); But someone know better coding than mine ? Playground : http://jsfiddle.net/UHyaD/ You can use a regex : var id = $(".main").attr("class").match(/id_(\d*)/)[1]; JSfiddle : http://jsfiddle.net/scaillerie/UHyaD/1/ You can use match function:
