Hello everyone, I need to know which class multidimensional arrays in Java extends exactly? When we assign Object[] ref=new int[]{1,2,3}; the compiler complains that the objects are of different types. So it seems that one dimensional arrays extend Object; I know that already. But when we assign Object[] ref2=new int[][]{{1,2,3},{...
Is there a built-in way to multiply every member of an array by some number in-place? Example: Dim volts () as Double = {1.243, 0.534, 5.343, 2.223, 4.334} Dim millivolts (4) as Double = volts.MultiplyEachBy(1000) 'something like this ...
I need the following array in alphabetical order (at all levels), but asort doesn't seem to work because I have a recursive call in my function (or so I think); it only partially sorts my array, so I'll have chunks of it that are alphabetized, but they'll be out of order. Help! Ex. Directory Listing: apartments.html js/ application....
The question pretty much sums it up. "dtrace 'print an associative array'" has exactly one google hit and the similar searches are equally useless. EDIT: If I were to use an aggregation, I'm not aware that I'd still be able to remove entries. My application requires that I be able to do things like: file_descriptors[0] = "stdin" fil...
I've got an array of sites like so... $data = array( 'http://site1.net/', 'http://site2.net/', 'http://site3.org/' ); And I'd like to create a script that iterates over the array and creates a list of input text fields containing each array element... Example: 1. [] http://site1.net/ 2. [] http://site2.net/ 3. [] http://site2.net/...
I changed the single quotes to doubles quotes after I faced th following problem: $lang = array( 'let's do something...' ); Now I have this problem: $lang = array( "tagline_h2" => "A paragraph...<a href="#">this is a link</a>" ); What should I do? ...
I would like to know how to adapt section 11.14 of the C++-FAQ-lite to arrays. Basically, I would want something like this: class Pool { public: void* allocate(size_t size) {...} void deallocate(void* p, size_t size) {...} }; void* operator new[](size_t size, Pool& pool) { return pool.allocate(size); } void operator delete[](void*...
Hi all. Is there any simple way of checking if all elements of an array are instances of a specific type without looping all elements? Or at least an easy way to get all elements of type X from an array. Thank you. Regards, Diogo ...
Hi there, I hope this question hasn't been asked before: I'm using the ancestry gem to manage my tree structure. I'm using a function which returns the descendants of a node to a certain number of levels. Here's a simplistic example of what it's returning: [{:name => 'node 1', :depth => 1}, {:name => 'node 2', :depth => 2} {:name => '...
I wanna design an Entity Class which has a String[] property. This String Array always has two values and I dont want Hibernate (or rather JPA) create an extra table for this but embed this two String values directly into the table. Is this possible and if so how? ...
I have a var dump of unserialized data that looks like this array(3) { ["product_options"]=> array(1) { [594]=> string(4) "2497" } ["is_edp"]=> string(0) "" ["base_price"]=> float(17.99) } Can anyone help me get the data out of this array. I specifically need to access the [594] and get it to print out 2497. Any solutions or advi...
From an array $my_array = array('a','b','c','d','e'); I want to get two DIFFERENT random elements. With the following code: for ($i=0; $i<2; $i++) { $random = array_rand($my_array); # one random array element number $get_it = $my_array[$random]; # get the letter from the array echo $get_it; } it is possible to g...
I'm trying to build an array of prime numbers in Java. if(c % 2 != 0 || c % 3 != 0 || c % 5 != 0) { n.add(c); } But my program seems to ignore the condition and just adds every number to my list. But if I just use one condition for example, if(c % 2 != 0) The code works perfectly in ignoring any number which is a multiple of ...
Hi, I have some objects that have 3 sorting options: quality, quatity and a compare against the other object, sorted by that order. - (NSComparisonResult) compare: (MyObject *) obj { if (self.quality > obj.quality) return NSOrderedAscending; else if (self.quality < obj.quality) return NSOrderedDescending; if (self.quantity > obj.quant...
When soritng an array made of a mix of strings, null values and zeros, i get the result not properly as exptected, null values seem to get sorted as if they were 'null' strings. I did this (tested on FireFox): var arr1 = arr2 = [null, "b", "c", "d", null, "e", 0, "g", null, 0, "h", "i", "l", "m", "n", "o", "p", "ne", "nur", "nimbus"]; ...
Hello I want to store arrays in an array, but I don't know exactly how to do it. What I want is: I have an array called, for example, array. In a method I want to append an item to this array, this item would be an array too. For example, this would be in my first array: (every item of it is appended when the method is called) {1,2}...
I've got two arrays, one with IDs and one with Names: $ids = array(4, 13, 6, 8, 10); $names = array('alice', 'bob', 'charles', 'david', 'elizabeth'); I need to update the db so that the rows with the ids have the names in the array. Here's the tricky bit: I also have two ints: $special_name = 2; // the index in $names, in this case w...
I'm trying to create a structure storing strings and I'm getting an error incompatible types when I try and insert as string into the array. This my first time working with a program in C. Could somebody help spot my problem. This is my implementation of list.c struct list *init_list(int num) { struct list *p; p = malloc(LIS...
hey all, i use array_map from time to time to write recursive methods. for example function stripSlashesRecursive( $value ){ $value = is_array($value) ? array_map( 'stripSlashesRecursive', $value) : stripslashes( $value ); return $value; } Question: say i wanna put this function in a static class, how would i use...
This is the most optimal way of dealing with a multilingual website I can think of, right now (not sure) which doesn't involve gettext, zend_translate or any php plugin or framework. I think its pretty straight forward: I have 3 languages and I write their "content" in different files (in form of arrays), and later, I call that content ...
