  • Printing the results in the original order

    - by Sam
    String[] numbers = new String[] {"3", "4", "s", "a", "c", "h", "i", "n", "t", "e", "n", "d", "u", "l", "k"}; Map<String, Integer> map = new HashMap<String, Integer>(); for (int i = 0; i < numbers.length; i++) { String key = numbers[i]; if (map.containsKey(key)) { int occurrence = map.get(key); occurrence++; map.put(key, occurrence); } else { map.put(key, 1); }// end of if else }// end of for loop Iterator<String> iterator = map.keySet().iterator(); while (iterator.hasNext()) { String key = iterator.next(); int occurrence = map.get(key); System.out.println(key + " occur " + occurrence + " time(s)."); } This program tries to count the number of occurrences of a string. When I execute it I am getting the answer, but the output is not in the original order, it is shuffled. How can I output the strings in the original order?

  • Displaying text in correct column

    - by wrongusername
    After getting a helpful answer here, I have run into yet another problem: displaying two or more strings in the column I want it to be displayed in. For an example of the problem I have, I want this output: Come here! where? not here! but instead get Come here! where? not here! when I use the code cout << left << setw(30) << "Come here!" << " where? " << setw(20) << "not here!" << endl; I made sure (I think) that the width of both columns could contain the two strings, but no matter how large I set the width of the columns to be, the error is still there.

  • Make div expand only horizontally when more floating divs are added to it

    - by Wesam
    I am trying to make a div that contains other floating divs to adjust its width such that adding more floating divs (dynamically using jQuery) will only expand the div in its width, not allowing the floating divs to create a new line. Therefore, I want to fix this issue such that each div with class grid-row only expands in width, and so I will be able to scroll using the overflow: scroll for the parent grid div. I have searched a lot for answers, and it seems that it is a famous issue. However, non of the answer solved my problem. I am currently doing this: <div id="grid_container"> <div id="grid"> <div class="grid_row"> <div class="module" id="experience"> Experience </div> <div class="header"> Google </div> <div class="header"> Microsoft </div> </div> <div class="grid_row"> </div> </div> </div> CSS: body { } #grid_container { margin: 50px auto; width: 500px; height: 500px; padding: 10px; border: black solid 1px; } #grid { overflow:scroll; height: 100%; } .grid_row { clear: both; height: 50px; } .module, .header{ padding: 10px; float: left; border: gray solid 1px; }

  • Avoiding instanceof in Java

    - by Mark Lutton
    Having a chain of "instanceof" operations is considered a "code smell". The standard answer is "use polymorphism". How would I do it in this case? There are a number of subclasses of a base class; none of them are under my control. An analogous situation would be with the Java classes Integer, Double, BigDecimal etc. if (obj instanceof Integer) {NumberStuff.handle((Integer)obj);} else if (obj instanceof BigDecimal) {BigDecimalStuff.handle((BigDecimal)obj);} else if (obj instanceof Double) {DoubleStuff.handle((Double)obj);} I do have control over NumberStuff and so on. I don't want to use many lines of code where a few lines would do. (Sometimes I make a HashMap mapping Integer.class to an instance of IntegerStuff, BigDecimal.class to an instance of BigDecimalStuff etc. But today I want something simpler.) I'd like something as simple as this: public static handle(Integer num) { ... } public static handle(BigDecimal num) { ... } But Java just doesn't work that way. I'd like to use static methods when formatting. The things I'm formatting are composite, where a Thing1 can contain an array Thing2s and a Thing2 can contain an array of Thing1s. I had a problem when I implemented my formatters like this: class Thing1Formatter { private static Thing2Formatter thing2Formatter = new Thing2Formatter(); public format(Thing thing) { thing2Formatter.format(thing.innerThing2); } } class Thing2Formatter { private static Thing1Formatter thing1Formatter = new Thing1Formatter(); public format(Thing2 thing) { thing1Formatter.format(thing.innerThing1); } } Yes, I know the HashMap and a bit more code can fix that too. But the "instanceof" seems so readable and maintainable by comparison. Is there anything simple but not smelly?

  • How to learn a new programming language? And how to choose the appropriate language?

    - by Sebi
    Unfortunately my last question was closed, so I reformulated the question: I know this question was here a lot of times and can't be answered at all, but im not looking for a single name, but rather for an advice in my situation. I learned programming with Java and now I'm developing in Java for more or less 5 years (at the university) and I thinks my programming skills their are really ok/average. I have also small experience in C/C++ and C#. Now I have some spare time and I'd like to learn a new language or deepen the knowledge of Java/C/C++. But how to choose the right language to learn? I'd like to learn a language which will be usefull in the future concerning working in a software development business? I know there is no single answer, but I'm sure you could mention some languages that are more usefull than others. And what's the best way to learn such a language efficiently (bearing in mind that one has already learned some other languages)? Just doing tutorials? Or trying to implement a project? Trying to move a Java project to the new language?

  • How can pointers to functions point to something that doesn't exist in memory yet? Why do prototypes have different addresses?

    - by Kacy Raye
    To my knowledge, functions do not get added to the stack until run-time after they are called in the main function. So how can a pointer to a function have a function's memory address if it doesn't exist in memory? For example: using namespace std; #include <iostream> void func() { } int main() { void (*ptr)() = func; cout << reinterpret_cast<void*>(ptr) << endl; //prints 0x8048644 even though func never gets added to the stack } Also, this next question is a little less important to me, so if you only know the answer to my first question, then that is fine. But anyway, why does the value of the pointer ( the memory address of the function ) differ when I declare a function prototype and implement the function after main? In the first example, it printed out 0x8048644 no matter how many times I ran the program. In the next example, it printed out 0x8048680 no matter how many times I ran the program. For example: using namespace std; #include <iostream> void func(); int main() { void ( *ptr )() = func; cout << reinterpret_cast<void*>(ptr) << endl; } void func(){ }

  • Just a small help about switch's use

    - by Laurent Fournier
    If an answer on this already exist, my apologies i've not found on this question... is this statement correct if i want presice actions on integers from -2 to 0, and for those between 1 and 6 apply the same methods with only my integer who'll change ? Like this: public void setCaseGUI(Point pt, int i, boolean b){ plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setSelected(b); plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setIcon(null); switch(i) { case -2: plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setText("F"); plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setForeground(Color.red); break; case -1: plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setText("B"); plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setForeground(Color.red); break; case 0: plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setText(""); plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setForeground(null); break; case 1: case 2: case 3: case 4: case 5: case 6: case 7: case 8: plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setText(String.valueOf(i)); plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setForeground(null); break; default: System.out.println("Erreur de changement d'état/case !"); } } Please don't be too harsh on me i've started to learn dev only a few month ago

  • Weird CSS behavior... removing a 1px border makes <DIV> move about 20px

    - by John
    I have the following: CSS #pageBody { height: 500px; padding:0; margin:0; /*border: 1px solid #00ff00;*/ } #pageContent { height:460px; margin-left:35px; margin-right:35px; margin-top:30px; margin-bottom:30px; padding:0px 0 0 0; } HTML <div id="pageBody"> <div id="pageContent"> <p> blah blah blah </p> </div> </div> </div> If I uncomment the border line in pageBody, everything fits sweetly... I had the border on to verify things were as expected. But removing the border, pageBody drops down the page about 20px, while pageContent does not appear to move at all. Now this is not the real page, but a subset. If nothing's obvious I can attempt to generate a working minimal sample, but I thought there might be an easy quick answer first. I see the same exact problem in Chrome and IE8, suggesting it's me not the browser. Any tips where to look? I wondered maybe the 1px border was some tipping point making the contents of a div just too big, but changing #pageContent height to e.g 400 makes no difference, other than clipping the bottom off that div.

  • Is there any good reason for private methods existence in C# (and OOP in general)?

    - by Piotr Lopusiewicz
    I don't mean to troll but I really don't get it. Why would language designers allow private methods instead of some naming convention (see __ in Python) ? I searched for the answer and usual arguments are: a) To make the implementation cleaner/avoid long vertical list of methods in IDE autocompletion b) To announce to the world which methods are public interface and which may change and are just for implementation purpose c) Readability Ok so now, all of those could be achieved by naming all private methods with __ prefix or by "private" keyword which doesn't have any implications other than be information for IDE (don't put those in autocompletion) and other programers (don't use it unless you really must). Hell, one could even require unsafe-like keyword to access private methods to really discourage this. I am asking this because I work with some c# code and I keep changing private methods to public for test purposes as many in-between private methods (like string generators for xml serialization) are very useful for debugging purposes (like writing some part of string to log file etc.). So my question is: Is there anything which is achieved by access restriction but couldn't be achieved by naming conventions without restricting the access ?

  • yet another logic.

    - by Sunil
    I'm working on a research problem out of curiosity and I don't know how to program the logic that I've in mind. Let me explain it to you : I've 4 vectors say for example, v1 = 1 1 1 1 v2 = 2 2 2 2 v3 = 3 3 3 3 v4 = 4 4 4 4 Now what I want to do is to add them combination-wise. i.e v12 = v1+v2 v13 = v1+v3 v14 = v1+v4 v23 = v2+v3 v24 = v2+v4 v34 = v3+v4 Till this step it is just fine. The problem/trick is now, at the end of each iteration I give the obtained vectors into a black box function and it returns only few of the vectors say v12, v13 and v34. Now, I want to add each of these vectors one vector from v1,v2,v3,v4 which it hasn't added before. For example v3 and v4 hasn't been added to v12 so I want to create v123 and v124. similarly for all the vectors like, v12 should become : v123 = v12+v3 v124 = v12+v4 v13 should become : v132 // this should not occur because I already have v123 v134 = v13+v4; v14,v23 and v24 cannot be considered because it was deleted in the black box function so all we have in our hands to work with is v12,v13 and v34. v34 should become : v341 // cannot occur because we have 134 v342 = v34+v2 It is important that I do not do all at one step at the start like for example I can do (4 choose 3) 4C3 and finish it off but I want to do it step by step at each iteration. I've asked a modified version of this question before (without including the black box function) and got answers here. Can anybody tell me how to do it when the black box function is included ? A modification of the previous answer would also be great. Thanks in advance.

  • How can I call multiple nutrient information from ESHA Research API? (apid.esha.com)

    - by user1833044
    I want to call ESHA Research nutrient REST API. I cannot seem to figure out how to call multiple nutrients using ESHA REST API. So far I am calling the following and only able to retrieve the calories, or protein, or another type of nutrient information. So I was hoping someone had experience in retrieving all the nutrient information with one call. Is this possible? This is how I call to retrieve the TWIX nutrient http://api.esha.com/analysis?apikey=xxxx&fo=urn:uuid:81d268ac-f1dc-4991-98c1-1b4d3a5006da (returns calories, please note the api key is not xxxx but instead a key generated from Esha once you sign up as developer) The return is JSON format. If I want to call fat it would be the following http://api.esha.com/analysis?apikey=xxxx&fo=urn:uuid:81d268ac-f1dc-4991-98c1-1b4d3a5006da&n=urn:uuid:589294dc-3dcc-4b64-be06-c07e7f65c4bd How can I make a call once and get a return of all the nutrients (so Fat, Calories, Carbs, Vitamins, etc..) for a particular food ID? I have researched and looked at this for a while and cannot seem to find the answer. Thanks in advance for your help.

  • Conditional fieldgroups/fieldsets in Drupal 7

    - by seane
    Background: In Drupal 7, I have created a form with CCK (aka the Field UI). I used the Field group module to create a fieldgroup, but I need it to be conditional, meaning it will only display depending on a previous answer. Previous research: To create a conditional field, you can use hook_form_alter() to edit the #states attribute like so: function MYMODULE_form_alter(&$form, &$form_state, $form_id) { if ($form_id == 'person_info_node_form') { // Display 'field_maiden_name' only if married $form['field_maiden_name']['#states'] = array( 'visible' => array( ':input[name="field_married[und]"]' => array('value' => 'Yes'), ), ); } } However, there seems to be no way to use the States API for fieldgroups. One thing to note is that, while fields are stored in $form, fieldgroups are stored in $form['#groups'] as well as in $form['#fieldgroups']. I don't know how to distinguish between these, and with this in mind, I have tried to apply a #states attribute to a fieldgroup in the same manner as above. However, it only produces server errors. Question: Is there a way to make a fieldgroup display conditionally using the States API or some alternative approach?

  • Learning Java Swing (GUI builder or not?)

    - by Paul
    Well I know basic Java and wanted to learn Swing so of course looked at the Sun website first, where this tutorial is. I was going to start it but realised it relied heavily on NetBeans, which I'm not sure about. I'm not sure because it's learning that I want to acheive, not a nice looking program. So I thought using NetBeans like this would be great once I know it, but I don't want to be building things without a clue what's going on underneath, and of course this could also cause problems later. My first question is is this the right way to do it, should I try not to rely on an IDE heavily? Looking through questions on the site most people recommend using the Sun tutorial, and I've only seen one answer that agrees with what I'm thinking, and they linked to this resource which looks promising. Or perhaps I'm getting the wrong idea of the Sun tutorial, perhaps it doesn't rely on the IDE, it just seemed like that. My second question is, if you agree with me, what resources (apart from the one above) would you recommend? Thanks for your answers.

  • STL in C++ how does it work

    - by helloWorld
    I have very technical question, I was working with C, and now I'm studying C++, if I have for example this class class Team { private: list<Player> listOfPlayers; public: void addPlayer(string firstName, string lastName, int id) { Player newPlayer(string firstName, string lastName, int id); listOfPlayers.push_back(Player(string firstName, string lastName, int id)); } } this is a declaration of the Player: class Player{ private: string strLastName; string strFirstName; int nID; public: Player(string firstName, string lastName, int id); } and this is my constructor of Player: Player::Player(string firstName, string lastName, int id){ nId = id; string strFirstName = firstName; string strLastName = lastName; } so my question is when I call function addPlayer what exactly is going on with program, in my constructor of Account do I need to allocate new memory for new Account(cause in C I always use malloc) for strFirstName and strLastName, or constructor of string of Account and STL do it without me, thanks in advance (if you don't want to answer my question please at least give me some link with information) thanks in advance

  • Questions about "sets"

    - by James
    I have a test tomorrow that I am revising for and the lecturer has supplied some sample questions with no answers. I was hoping I could get some help with a couple of them. I've written what I think the answer is for them. 1. What is the type of the set {1, 2, 3}? integer/number 2. What is the type of the set {{1}, {2}, {3}}? integer/number (unsure what putting each number in {} does?) 3. What is the type of the set {{1}, {2}, {3}, empty}? integer/number 4. What is the type of the set {1, {2}, 3}? — is it well typed? integer/number 5. What is the type of the set {1, 2, john}? — is it well typed? unsure for a mixed set. Taking a complete guess of void or empty. Any help will be much appreciated.

  • Categorize data without consolidating?

    - by sqlnoob
    I have a table with about 1000 records and 2000 columns. What I want to do is categorize each row such that all records with equal column values for all columns except 'ID' are given a category ID. My final answer would look like: ID A B C ..... Category ID 1 1 0 3 1 2 2 1 3 2 3 1 0 3 1 4 2 1 3 2 5 4 5 6 3 6 4 5 6 3 where all columns (besides ID) are equal for IDs 1,3 so they get the same category ID and so on. I guess my thought was to just write a SQL query that does a group by on every single column besides 'ID' and assign a number to each group and then join back to my original table. My current input is a text file, and I have SAS, MS Access, and Excel to work with. (I could use proc sql from within SAS). Before I go this route and construct the whole query, I was just wondering if there was a better way to do this? It will take some work just to write the query, and I'm not even sure if it is practical to join on 2000 columns (never tried), so I thought I'd ask for ideas before I got too far down the wrong path. EDIT: I just realized my title doesn't really make sense. What I was originally thinking was "Is there a way I can group by and categorize at the same time without actually consolidating into groups?"

  • Sending arbitrarily long string over Java TCP socket

    - by bibismcbryde
    I have an Android app that communicates over a TCP socket with a server I wrote. The method I'm using now to read and write output works fine for smaller strings (up to 60kB) but I get an exception thrown when the string is much longer than that. Here is the relevant part of what I have for the server and client: Server: DataInputStream dis = null; DataOutputStream dos = null; try { dis = new DataInputStream(server.getInputStream()); dos = new DataOutputStream(server.getOutputStream()); String input = ""; input = dis.readUTF(); handle_input info = new handle_input(input, id); String xml = info.handle(); dos.writeUTF(xml); server.close(); } Client: Socket socket = null; DataOutputStream dos = null; DataInputStream dis = null; Boolean result; try { socket = new Socket(ip, port); dos = new DataOutputStream(socket.getOutputStream()); dis = new DataInputStream(socket.getInputStream()); dos.writeUTF(the_text); String in = ""; while (in.equals("")) { in += dis.readUTF(); } } How can I modify it to deal with potentially enormous Strings? I've been looking around and can't seem to find a clear answer. Thanks.

  • Comparing C++ input with array values

    - by Security_Gate
    Hey everyone, Over the last couple months I've still been slowly but surely trudging through C++, and I've run into a snag that I've been meaning to figure out. I've tried asking/reading/searching, but I could never find an appropriate answer. Maybe it is simply because the question is sort of difficult to ask. What I'm trying to do is at the end of my program, have the end sequence compare the input value with values within an Array. Do I have to loop a comparison sequence? Is there an easier way around this? #include <iostream> #include <string> using namespace std; int main () { string YesAnswers[5] = {"Y", "YES", "yes" "y"}; string Name; string YN; do { cout << "Enter your name: "; getline(cin, Name); cout << "Your name is "<< Name; cout <<"\nIs this correct? Y\N: "; cin >> YN; } while(YN == YesAnswers); system("Pause"); return 0; }

  • CakePHP "down for maintenance" page

    - by user1852176
    I found this post about how to create a "down for maintenance" page but I'm having some trouble getting it to work properly. define('MAINTENANCE', 1); if(MAINTENANCE > 0){ require('maintenance.php'); die(); } When I place this code in /webroot.index.php it works. However, the answer suggests adding an IP address check so that if it's down, I would still be able to view it and make sure any updates went through smoothly. So, it would look something like this define('MAINTENANCE', 0); if(MAINTENANCE > 0 && $_SERVER['REMOTE_ADDR'] !='188.YOUR.IP.HERE'){ require('maintenance.php'); die(); } The issue is, my IP address will NOT be detected by cake. I've typed echo $_SERVER['REMOTE_ADDR'] and it just shows ::1. I also tried using my user_id but I got the following error Class 'AuthComponent' not found in.... I tried /index.php and /App/index.php but the maintenance page wasn't triggered and the page loads normally.

  • Is JDEE worth using?

    - by User1
    I see many nice feature of JDEE in Emacs. However installation seems to be a bit involved, especially in Windows so I want to see if others found it useful. I use Eclipse and NetBeans and there are some decent features to these products. However, I really like the idea of a scripted language like Lisp built into my IDE so I can change most features on-the-fly. So I want to give JDEE a shot, but I've heard from more than one advanced Emacs user that they don't even need JDEE. I wonder if those people even tried JDEE or if they are just doing simple Java projects. Has anyone tried JDEE and liked it? Are there features in Emacs that make JDEE fairly pointless? Please no "try Eclipse" comments..I have used it and it has nice features, but I want to give Emacs a fair shot. UPDATE: See my accepted answer. I tried JDEE for a while but gave it up for eclipse and have never looked back. Happily ever after.

  • Can a pc with a 1.2 ghz dual core run VS 2013? [on hold]

    - by moo2
    Edit: This question is about a tool used for programming, Microsoft Visual Studio 2013. I already read the minimum requirements for VS 2013 before I posted or I wouldn't have asked the question. I searched on the web for an answer for a few hours before posting. Why should I go out and spend $400 on a laptop if I can spend less than $100 and use it to learn how to program? In the context of the question it is clear I was not asking for advice on what laptop to buy and it was also clear I was not asking for someone to walk me through the system requirements of VS 2013. This is a vast community and I was wondering if someone in this vast community would have experience in dealing with my question. In other words has anyone ever tried anything like it? If I had an old computer sitting around I would have tested it. At the moment all I have is a friend's Chromebook I'm borrowing. End Edit. I know the requirements for Microsoft Visual Studio 2013 state 1.6 ghz processor. I'm looking at getting a laptop for school and I found one that is old but cheap and would work for college. The Dell D430 I'm looking at getting has a 1.2ghz Core 2 Duo CPU, 80GB HD, 2GB RAM, and Windows 7 Home Premium. It's refurbished. I can get it for less than most phone's cost and from a Microsoft Authorized Refurbisher. I know it's not a skyrim rig but it's lightweight and can handle being a college laptop and doing word processing. Would Visual Studio 2013 run at all? If it is slower I'm not concerned. I just want to know if it would work and compile my assignments and run them? I'd be using this laptop for doing assignments and learning programming languages not for coding the next social media sensation.

  • Need help finding a unique value in array

  • DOS "pause" in Linux?

    - by user2930466
    Firstly, I'm REALLY new to programming. I've just started my first programming class two weeks ago, and I apologize if I sound newbish. My professor wants me to implement a "press any key to continue..." thing in my program. Basically when I run a program, he wants one line to come up [like printf("jfdskaljlfja");] then what would come up is "press any key to continue," before the next line runs. he told us that the DOS equivalent is system("pause"), but he wants us to do it linux. This is what my code looks like: #include <stdio.h> int main() { printf("This is the first line of this program); system("pause"); printf("This is the second line); } Except he wants us to do this in Linux, so system("pause") won't work in this case. Is there a way to have it do exactly what pause does, but in linux terms? again, sorry if i sound newbish. thank you so much! Also, he doesn't really care if the code is efficient or anything, as long as it runs. Again, i'm really new to programming, so the simplest answer would be much appreciated :)
