  • Java queue and multi-dimension array

    - by javaLearner.java
    First of all, this is my code (just started learning java): Queue<String> qe = new LinkedList<String>(); qe.add("b"); qe.add("a"); qe.add("c"); qe.add("d"); qe.add("e"); My question: Is it possible to add element to the queue with two values, like: qe.add("a","1"); // where 1 is integer So, that I know element "a" have value 1. If I want to add a number let say "2" to element a, I will have like a = 3. If this cant be done, what else in java classes that can handle this? I tried to use multi-dimention array, but its kinda hard to do the queue, like pop, push etc. (Maybe I am wrong) How to call specific element in the queue? Like, call element a, to check its value. [Note] Please don't give me links that ask me to read java docs. I was reading, and I still dont get it. The reason why I ask here is because, I know I can find the answer faster and easier.

  • How do I declare and initialize a 2d int vector in C++?

    - by FrankTheTank
    I'm trying to do something like: #include <iostream> #include <vector> #include <ctime> class Clickomania { public: Clickomania(); std::vector<std::vector<int> > board; bool move(int, int); bool isSolved(); void print(); void pushDown(); }; Clickomania::Clickomania() : board(12, std::vector<int>(8,0)) { srand((unsigned)time(0)); for(int i = 0; i < 12; i++) { for(int j = 0; j < 8; j++) { int color = (rand() % 6) + 1; board[i][j] = color; } } } However, apparently I can't initialize the "board" vector of vectors this way. How can I create a public member of a 2d vector type and initialize it properly?

  • jquery specific show buttons on hover

    - by bob
    I have an application creating a bunch of divs through a loop. Each div has the class "product" so it looks like <div class="product"> !.....stuff here ....! <div class="show_on_hover">...buttons here... </div> </div> so there are about 12 of these same divs per page. I would like to hover over a specific one and show the specific "show_on_hover" div which is initially set to display:none. $('.product').hover(function() { $(.show_on_hover).show(); }, function () { $(.show_on_hover).hide(); } ); That is what I have so far but it will show ALL of the .show_on_hovers on the page so I am wondering how to get only the specific one you have moused over to show. This effect is seen on youtube when you mouseover any of the comments, and some comment tools pop up. Thanks!

  • How to set a predefined value in a form in Rails

    - by marco
    So I just got started in Rails, and I'm trying to create an Object (a book_loan in my case) with a Form. The thing is that I get to this form by clicking on a book, so I pass the book_id as a parameter, like localhost:3000/loans/new?id=1. Now I don't want the user to be able to set the book id field in the form, since I already know the id. So my question is how to set the value in the form. I have been trying things like: <% form_for(@loan) do |f| %> <%= f.error_messages %> ... <%= @loan.book_id = params[:id] %> <%= f.submit 'Create' %> <% end %> without any success. Does anybody have a hint for me?

  • Illegal Start of Expression

    - by Kraivyne
    Hello there, I have just started to learn the very basics of Java programming. Using a book entitled "Programming Video Games for the Evil Genius". I have had an Illegal Start of Expression error that I can't for the life of me get rid of. I have checked the sample code from the book and mine is identical. The error is coming from the for(int i = difficulty; i = 0; i- - ) line. Thanks for helping a newbie out. import javax.swing.*; public class S1P4 {public static void main(String[] args) throws Exception { int difficulty; difficulty = Integer.parseInt(JOptionPane.showInputDialog("How good are you?\n"+ "1 = Great\n"+"10 = Terrible")); boolean cont = false; do { cont = false; double num1 = (int)(Math.round(Math.random()*10)); double num2; do { num2 = (int)(Math.round(Math.random()*10)); } while(num2==0.0); int sign = (int)(Math.round(Math.random()*3)); double answer; System.out.println("\n\n*****"); if(sign==0) { System.out.println(num1+" times "+num2); answer = num1*num2; } else if(sign==1) { System.out.println(num1+" divided by"+num2); answer = num1/num2; } else if(sign==1) { System.out.println(num1+" plus "+num2); answer = num1+num2; } else if(sign==1) { System.out.println(num1+" minus "+num2); answer = num1-num2; } else { System.out.println(num1+" % "+num2); answer = num1%num2; } System.out.println("*****\n"); for(int i = difficulty; i >= 0; i- - ) { System.out.println(i+"..."); Thread.sleep(500); } System.out.println("ANSWER: "+answer); String again; again = JOptionPane.showInputDialog("Play again?"); if(again.equals("yes")) cont = true; } while(cont); } }

  • Routing Skype call to another Voip company

    - by Anarchist
    Hello, As my project to do over this summer I would like to create a program that answers a Skype call using the Skype API and allows a user to connect to another VOIP provider (through SIP) and make calls by dialling through the client callers Skype application. I understand that the Skype API allows me to answer and receive keypad input, but I'm stuck on actually sending the sound of the call to a SIP client. Is there an API/library that would allow me to take the Skype receiving audio as input in the SIP client? Is this even possible? I'm not tied to a language but I had planned on using Python. Thanks.

  • PC to Macbook Pro Transition - Getting (re)started?

    - by Torus Linvald
    I'm in my second computer science course right now. I've enjoyed programming so far, but really have just scraped my way by. I've not done much programming outside of required class work. For similar reasons, I never really invested in downloading/learning software to help me program (IDE's, editors, compilers, etc). I know it sounds tedious, but my current setup is: notepad++ for coding; Filezilla to transfer .cpp & .h files to school's aludra/unix and compiling; unix tells me where my bugs are and I go back to notepad++ to debug; repeat until done. This isn't fun - and I know it could be easier. But I put it off knowing that I was soon going to switch to a Mac. And, tomorrow, I'm switching. So... How should I set up my Macbook for the best programming experience? What IDEs and editors and debuggers and so on should I download? How will Mac programming differ from PC? I'm open to all ideas and comments, even the most basic. (Background - I'm learning/programming in C++ right now. Next semester, my classes switch to Java. I'm also going to take a class in web development, with HTML/CSS/Javascript/PHP. My new laptop will be a late 2009 Macbook Pro with Leopard, or maybe Snow Leopard. Free would be preferrable for all programs.) Thank you all.

  • Error handling with Python + Pylons

    - by ensnare
    What is the proper way to handle errors with Python + Pylons? Say a user sets a password via a form that, when passed to a model class via the controller, throws an error because it's too short. How should that error be handled so that an error message gets displayed on the web page rather than the entire script terminating to an error page? Should there be any error handling in the controller itself? I hope I am explaining myself clearly. Thank you.

  • PUT-ing a form to update a row, but I can't find the id. Where is it?

  • Putting a variable name = value format in Ruby

    - by Calm Storm
    Hi, I would like to add some debugs for my simple ruby functions and I wrote a function as below, def debug(&block) varname = block.call.to_s puts "#{varname} = #{eval(varname,block)}" end debug {:x} #prints x = 5 debug {:y} #prints y = 5 I understand that eval is evil. So I have two questions. Is there any way to write that debug method without using eval? If NO is there a preferred way to do this? Is there any way to pass a list of arguments to this method? I would ideally prefer debug {:x, :y. :anynumOfvariables}. I could not quite figure out how to factor that into the debug method (i.e, to take a list of arguments)

  • Getting MAX_INT from NSDateComponents

    - by MattyW
    I'm trying to write my first iPhone app, and I'm using a date picker object for the user to enter their date of birth. Part of my app requires the year in int format. I've added the code as below. What's odd is that 'month' gets the right value. But day and year seem to be stuck at MAX_INT (2147483647). Can anyone tell me what I'm doing wrong? -(IBAction)dateOfBirthChanged:(id)sender { NSCalendar* calender = [NSCalendar currentCalendar]; NSDateComponents* dateComponents = [calender components:NSMonthCalendarUnit fromDate:[datepicker date]]; NSInteger day = [dateComponents day]; NSInteger month = [dateComponents month]; NSInteger year = [dateComponents year]; label.text = [NSString stringWithFormat:@"Your year of birth is %d", year]; }

  • Python - a clean approach to this problem?

    - by Seafoid
    Hi, I am having trouble picking the best data structure for solving a problem. The problem is as below: I have a nested list of identity codes where the sublists are of varying length. li = [['abc', 'ghi', 'lmn'], ['kop'], ['hgi', 'ghy']] I have a file with two entries on each line; an identity code and a number. abc 2.93 ghi 3.87 lmn 5.96 Each sublist represents a cluster. I wish to select the i.d. from each sublist with the highest number associated with it, append that i.d. to a new list and ultimately write it to a new file. What data structure should the file with numbers be read in as? Also, how would you iterate over said data structure to return the i.d. with the highest number that matches the i.d. within a sublist? Thanks, S :-)
