  • Why does Java not have any destructor like C++?

    - by Abhishek Jain
    Java has its own garbage collection implementation so it does not require any destructor like C++ . This makes Java developer lazy in implementing memory management. And Garbage Collection is very expensive. Still we can have destructor along with garbage collector where developer can free resources and which can save garbage collector's work. This might improves the performance of application. Why does Java not provide any destructor kind of mechanism? Developer does not have control over GC but he/she can control or create object. Then why not give them ability to destruct the objects?

  • dangling pointer, reason for value change after free()?

    - by Aman Jain
    In the following code segment, after free(x), why does y becomes 0? As per my understanding, the memory in the heap that was being pointed to by x, and is still being pointed by y, hasn't been allocated to someone else, so how can it change to 0? And moreover, I don't think it is free(x) that changed it to 0. Any comments? #include <stdio.h> int main ( int argc, char *argv[] ) { int *y = NULL; int *x = NULL; x = malloc(4); *x = 5; y = x; printf("[%d]\n", *y); //prints 5 free(x); printf("[%d]\n", *y); //why doesn't print 5?, prints 0 instead return 0; }

  • FF extension: displaying an array of string elements in a sidebar

    - by sujay-jain
    I am developing a ff extension which displays a list of elements from an array (dynamic) in the sidebar. The array is dynamic and needs to be constructed in a function everytime the sidebar is opened (or any other event handler). Later, i will need to implement link functionality on parts of the string. What is the best way to go about this? I have created an empty sidebar and just know the label element as of now. menu, and menuitem dont work. What other elements can i use to display text in a good way which supports dynamic contruction. Is there some good tutorial/sample extension which i can see and learn?

  • Dynamic CSS class names in GWT

    - by Anupam Jain
    I am in the process of porting a simple CSS grid system to GWT. My CSS file currently has classes like .size1, .size2 etc., and I have a CSS resource that looks like - class MyResource extends CSSResource { @ClassName("size1") String size1(); @ClassName("size2") String size2(); // And so on } However what I really want, is to have a single function like the following - String size(int size); which will generate the appropriate class when passed the size as an integer at runtime. This is needed as I perform some calculations to determine the actual space available/needed for a widget in javascript and then attach the appropriate class name. Is this something that is even possible with GWT?

  • Facebook connect with iPhone not working?

    - by Atulkumar V. Jain
    Hi Everybody, I am trying to use Facebook connect in my application, but its not working as I desire. When I am trying to use the API Key and the API SecretKey of my application which I have registered with the facebook its not working. I have downloaded the code for the facebook. In the SessionViewController.m file when I pass my key values its not working. What I am trying to achieve is, when the app launches the first page is the Facebook Login Page. The user enters his username and password and then the next view should display. But nothing is happening, even the label doesn't display the username. Heres the code which I am using - (void)request:(FBRequest*)request didLoad:(id)result { NSArray* users = result; NSDictionary* user = [users objectAtIndex:0]; NSString* name = [user objectForKey:@"name"]; _label.text = [NSString stringWithFormat:@"Logged in as %@",name]; NSLog(@"Username is :- %@",name); FrontController *main = [[FrontController alloc] init]; [self.view addSubview:main.view]; [main release]; } I am not able to figure out what is wrong with this code. When I try with some other key values such as the key for connect application its working fine. Can anyone help me with this... Thanx in advance...
