  • How do I call a non-public method of a public class in Clojure?

    - by sramsay
    I'm calling the twitter4j library using Clojure like so: (def twitter (. (TwitterFactory.) getInstance)) This works fine when I call it as a script. But when I use gen-class, I get: java.lang.IllegalArgumentException: Can't call public method of non-public class: public java.lang.Object twitter4j.TwitterFactoryBase.getInstance() Is there a workaround for this?

  • Comparator interface

    - by 1ace1
    ok I was going to edit my previous question but i wasnt sure if it was the right way to do it so i'll just give another question about Comparator, now i want to be able to sort with different ways. I have a bank checks and i want to sort with checkNumber then checkAmount i managed to do it with checkNumber but couldnt figure out how with checkAmount here is how i did it for checkNumber: import java.util.Comparator; public class Check implements Comparator { private int checkNumber; private String description; private double checkAmount; public Check() { } public Check(int newCheckNumber, double newAmountNumber) { setCheckNumber(newCheckNumber); setAmountNumber(newAmountNumber); } public String toString() { return checkNumber + "\t\t" + checkAmount; } public void setCheckNumber(int checkNumber) { this.checkNumber = checkNumber; } public int getCheckNumber() { return checkNumber; } public void setAmountNumber(double amountNumber) { this.checkAmount = amountNumber; } public double getAmountNumber() { return checkAmount; } @Override public int compare(Object obj1, Object obj2) { int value1 = ((Check) obj1).getCheckNumber(); int value2 = ((Check) obj2).getCheckNumber(); int result = 0; if (value1 > value2){ result = 1; } else if(value1 < value2){ result = -1; } return result; } } import java.util.ArrayList; import java.util.Collections; import test.CheckValue; public class TestCheck { public static void main(String[] args) { ArrayList List = new ArrayList(); List.add(new Check(445, 55.0)); List.add(new Check(101,43.12)); List.add(new Check(110,101.0)); List.add(new Check(553,300.21)); List.add(new Check(123,32.1)); Collections.sort(List, new Check()); System.out.println("Check Number - Check Amount"); for (int i = 0; i < List.size(); i++){ System.out.println(List.get(i)); } } } thank you very much in advance and please tell me if im submiting things in the wrong way.

  • Which is the fastest idiomatic way to add all vectors (in the math sense) inside a Scala list?

    - by davips
    I have two solutions, but one doesn't compile and the other, I think, could be better: object Foo extends App { val vectors = List(List(1,2,3), List(2,2,3), List(1,2,2)) //just a stupid example //transposing println("vectors = " + vectors.transpose.map (_.sum)) //it prints vectors = List(4, 6, 8) //folding vectors.reduce { case (a, b) => (a zip b) map { case (x, y) => x + y } } //compiler says: missing parameter type for exp. function; arg. types must be fully known }

  • Vector Troubles in C++

    - by DistortedLojik
    I am currently working on a project that deals with a vector of objects of a People class. The program compiles and runs just fine, but when I use the debugger it dies when trying to do anything with the PersonWrangler object. I currently have 3 different classes, one for the person, a personwrangler which handles all of the people collectively, and a game class that handles the game input and output. Edit: My basic question is to understand why it is dying when it calls outputPeople. Also I would like to understand why my program works exactly as it should unless I use the debugger. The outputPeople function works the way I intended that way. Edit 2: The callstack has 3 bad calls which are: std::vector ::begin(this=0xbaadf00d) std::vector ::size(this=0xbaadf00d) PersonWrangler::outputPeople(this=0xbaadf00d) Relevant code: class Game { public: Game(); void gameLoop(); void menu(); void setStatus(bool inputStatus); bool getStatus(); PersonWrangler* hal; private: bool status; }; which calls outputPeople where it promptly dies from a baadf00d error. void Game::menu() { hal->outputPeople(); } where hal is an object of PersonWrangler type class PersonWrangler { public: PersonWrangler(int inputStartingNum); void outputPeople(); vector<Person*> peopleVector; vector<Person*>::iterator personIterator; int totalPeople; }; and the outputPeople function is defined as void PersonWrangler::outputPeople() { int totalConnections = 0; cout << " Total People:" << peopleVector.size() << endl; for (unsigned int i = 0;i < peopleVector.size();i++) { sort(peopleVector[i]->connectionsVector.begin(),peopleVector[i]->connectionsVector.end()); peopleVector[i]->connectionsVector.erase( unique (peopleVector[i]->connectionsVector.begin(),peopleVector[i]->connectionsVector.end()),peopleVector[i]->connectionsVector.end()); peopleVector[i]->outputPerson(); totalConnections+=peopleVector[i]->connectionsVector.size(); } cout << "Total connections:" << totalConnections/2 << endl; }

  • Undefined function in php

    - by Bidyut
    I wrote three methods in a class and one is calling another, but when I call the function outside through the object, it is showing an undefined function error for the second function. Here's my code: function resize_image(){ } function image_resize(){ $a = resize_image(); } When I run this, it shows resize_image() as undefined. Here's the error: Fatal error: Call to undefined function resize_image() in /home/vacayge/public_html/Major/Alpha1/classes/cUserImages.php on line 2090

    Can someone explain why the example with integers results in different values for x and y and the example with the list results in x and y being the same object? x = 42 y = x x = x + 1 print x # 43 print y # 42 x = [ 1, 2, 3 ] y = x x[0] = 4 print x # [4, 2, 3] print y # [4, 2, 3] x is y # True

  • slowing down a loop in a recursive function

    - by eco_bach
    I have a difficult problem with a recursive function. Essentially I need to 'slow down' a for loop within a function that repeatedly calls itself(the function); Is this possible, or do I need to somehow extract the recursive nature of the function? function callRecursiveFuncAgain(ob:Object):void{ //do recursive stuff; for (var i:int = 0; i < 4; i++) { _nextObj=foo callRecursiveFuncAgain(_nextObj); } }

  • Contact page MVC workflow

    - by alex
    All my previous projects have had this workflow on Contact pages User submits form Controller gets $_POST details Controller validates details (and sets error messages if necessary) Controller sends email Controller redirects to thanks page Is this the standard workflow? I used to validate everything in controllers, and then did some more reading and they recommended against it. Therefore, should I send the $_POST details to a helper type object and let it do all the work (validation/sending)?

  • Customs toString in Java not giving desired output and throwing error

    - by user2972048
    I am writing a program in Java to accept and validate dates according to the Gregorian Calendar. My public boolean setDate(String aDate) function for an incorrect entry is suppose to change the boolean goodDate variable to false. That variable is suppose tell the toString function, when called, to output "Invalid Entry" but it does not. My public boolean setDate(int d, int m, int y) function works fine though. I've only included the problem parts as its a long piece of code. Thanks public boolean setDate(int day, int month, int year){ // If 1 <= day <= 31, 1 <= month <= 12, and 0 <= year <= 9999 & the day match with the month // then set object to this date and return true // Otherwise,return false (and do nothing) boolean correct = isTrueDate(day, month, year); if(correct){ this.day = day; this.month = month; this.year = year; return true; }else{ goodDate = false; return false; } //return false; } public boolean setDate(String aDate){ // If aDate is of the form "dd/mm/yyyy" or "d/mm/yyyy" // Then set the object to this date and return true. // Otherwise, return false (and do nothing) Date d = new Date(aDate); boolean correct = isTrueDate(d.day, d.month, d.year); if(correct){ this.day = d.day; this.month = d.month; this.year = d.year; return true; }else{ goodDate = false; return false; } } public String toString(){ // outputs a String of the form "dd/mm/yyyy" // where dd must be 2 digits (with leading zero if needed) // mm must be 2 digits (with leading zero if needed) // yyyy must be 4 digits (with leading zeros if needed) String day1; String month1; String year1; if(day<10){ day1 = "0" + Integer.toString(this.day); } else{ day1 = Integer.toString(this.day); } if(month<10){ month1 = "0" + Integer.toString(this.month); } else{ month1 = Integer.toString(this.month); } if(year<10){ year1 = "00" + Integer.toString(this.year); } else{ year1 = Integer.toString(this.year); } if(goodDate){ return day1 +"/" +month1 +"/" + year1; }else{ goodDate = true; return "Invalid Entry"; } } Thank you
