  • C lang. -- Error: Segmentaion fault

    I don't understand why this would give me a seg fault. Any ideas? this is the function that returns the signal to stop the program: (below is the other function that is called within this) double bisect(double A0,double A1,double Sol[N],double tol,double c) { double Amid,shot; while (A1-A0 tol) { Amid = 0.5*(A0+A1); shot = shoot(Sol, Amid, c); if (shot==2.*Pi) { return Amid; } if (shot > 2.*Pi){ A1 = Amid; } else if (shot < 2.*Pi){ A0 = Amid; } } return 0.5*(A1+A0); } double shoot(double Sol[N],double A,double c) { int i,j; /Initial Conditions/ for (i=0;i for (i=buff+2;i return Sol[i-1]; } buff, l, N are defined using a #deine statement. l = 401, buff = 50, N = 2000 Thanks

  • ImageAdapter and ListView (java.lang.OutOfMemoryError: bitmap size exceeds VM budget)

    - by theDude
    Hi, I'm using ListView to display images which I provide through an ImageAdapter class. it works great on my device (and on many other devices which I tested it on), but somehow when I'm using the emulator and I'm long-pressing the up/down button - I'm getting an outOfMemory error after 10-15 seconds. I tried clearing cache, canceling cache, etc. - nothing helped. I know this crash is pretty rare (i couldn't reproduced it on any "real" device), but I can see on DDMS that "GC freed" are getting bigger during that long press and I can't find a way to clear them. Any help will be appreciated, Tnx.

  • Trying to write priority queue in Java but getting "Exception in thread "main" java.lang.ClassCastEx

    - by Dan
    For my data structure class, I am trying to write a program that simulates a car wash and I want to give fancy cars a higher priority than regular ones using a priority queue. The problem I am having has something to do with Java not being able to type cast "Object" as an "ArrayQueue" (a simple FIFO implementation). What am I doing wrong and how can I fix it? public class PriorityQueue<E> { private ArrayQueue<E>[] queues; private int highest=0; private int manyItems=0; public PriorityQueue(int h) { highest=h; queues = (ArrayQueue[]) new Object[highest+1]; <----problem is here } public void add(E item, int priority) { queues[priority].add(item); manyItems++; } public boolean isEmpty( ) { return (manyItems == 0); } public E remove() { E answer=null; int counter=0; do { if(!queues[highest-counter].isEmpty()) { answer = queues[highest-counter].remove(); counter=highest+1; } else counter++; }while(highest-counter>=0); return answer; } }

  • Implementation of java.lang.Random in PHP and C

    - by justinhj
    I'm looking for a random number generator that I can run in PHP, C and Java that will always return the same sequence of numbers for a given seed. Here's the Java implementation I would use: java.util.random source Whilst this would be fairly straightforward to port to C and PHP, there is potentially a lot of work to get all the edge cases correct and handle differences in number representation. I'd be extremely happy to just copy and paste a fully tested version should it exist.

Both the machines have Sun's java, the Linux machine has 1.6.0_10, while the Windows machine has 1.6.0_08, or maybe 07 or 06, I can't remember the exact number right now, and don't have the machine at hand. But even though the minor versions of the Javas are slightly different, the code shouldn't break like this. Does anyone understand what's wrong here?

  • Simplifier le code de vos beans Java à l'aide de Commons Lang, Guava et Lombok, par Thierry Leriche-Dessirier

    Bonjour à tous, Je vous propose un article intitulé "Simplifier le code de vos beans Java à l'aide de Commons Lang, Guava et Lombok". Synopsis : Un bean classique, représentant un chien par exemple, peut vite peser des centaines de lignes quand on l'équipe avec les méthodes classiques et indispensables (constructeurs, getters, setters, equals, hashCode, toString, compareTo), même s'il possède peu d'attributs. Dans cet article, nous verrons comment mettre un tel cabot au régime et lui faire une beauté à l'aide de Commons Lang, Guava et Lombok. Nous en profiterons pour comparer ces bibliothèques entre elles et avec le code Java habituel, sans oublier celui qu'Eclipse génère. L'article est disponible ici :
