  • How do I pass an array to a method?

    - by ambidextorous
    Hey, I have not been able to find a proper answer on any forums about this. But how exactly do I pass an array to a class constructor? public class TestArray { String name; String[] array; public TestArray(String name, String[] anArray){ this.name = name; int len = anArray.length; this.array = new String[len]; for (int i = 0; i < len; i++) { this.array[i] = new String(anArray[i]); } } public static void main(String[] args){ String[] anArray = new String[2]; anArray[0] = new String("Test"); anArray[1] = new String("Test2"); TestArray work = new TestArray("Jordan", anArray); // How to pass the array? } }

  • PHP in_array() can't even match a single character. Strict is set to true.

    - by solefald
    I've seen a million of these threads here already, and read through every single one already. Including some serious time Googling. Nothing complicated. All I have to do is check if a single character in a loop matches my alphabet array. print_r($alphabet); // all 26 letters Array ( [0] => a [1] => b [2] => c ... [23] => x [24] => y [25] => z ) print_r($emptyLetters); // dynamic array. Array ( [0] => b [1] => s ) foreach($alphabet as $letter): { echo $letter . '<br />' // Correctly prints out every letter from $alphabet. if(in_array($letter, $emptyLetters, true)): // $strict is set // do something endif; } What the hell is going on??? I do not understand what i am doing wrong.... I tried every combination and option possible, but for some reason even array_search() is bit working...

  • PHP Notice: Undefined index when looping array...

    - by Jonathan
    Hi, I'm looping a two-dimensional array like this: if (!empty($aka)) { foreach ($aka as $ak) { if($ak["lang"]=="es") { $sptitle=$ak["title"]; } } } Pretty simple. If the array ($aka) is not empty I loop trough it and when it finds that the "lang" index is equal to "es" I just save the "title" value for that index in $sptitle. The problem is that the array ($aka) contains a lot of information and sometimes there is no "lang" index... and I get this error: Notice: Undefined index: lang. How can I fix this??? This is a extract of the array to help you understand. Notice that [1] doesn't have a [lang] index but [2] does have: [1] =&gt; Array ( [title] =&gt; The Lord of the Rings: The Motion Picture [year] =&gt; [country] =&gt; USA [comment] =&gt; promotional title ) [2] =&gt; Array ( [title] =&gt; Señor de los anillos: La comunidad del anillo, El [year] =&gt; [country] =&gt; Argentina [comment] =&gt; Chile, Mexico, Peru, Spain [lang] =&gt; es ) Thanks!

  • Parsing a tweet to extract hashtags into an array in Python.

    - by Scott
    I am having a heck of a time taking the information in a tweet including hashtags, and pulling each hashtag into an array using Python. I am embarrassed to even put what I have been trying thus far. For example, "I love #stackoverflow because #people are very #helpful!" This should pull the 3 hashtags into an array.

  • When should an array name be treated as a pointer and when does it just represent the array itself? [duplicate]

    - by user1087373
    This question already has an answer here: When is an array name or a function name 'converted' into a pointer ? (in C) 4 answers I just made a test program after reading the book and the result turned out confusing: #include <stdio.h> int main(void) { char text[] = "hello!"; printf("sizeof(text):%d sizeof(text+2):%d sizeof(text[0]):%d \n",(int)sizeof(text), sizeof(text+2), sizeof(text[0])); printf("text:%p sizeof(text):%d &text:%p sizeof(&text):%d \n",text, sizeof(text), &text, sizeof(&text)); printf("text+1:%p &text+1:%p \n", text+1, &text+1); return 0; } The result: sizeof(text):7 sizeof(text+2):4 sizeof(text[0]):1 text:0xbfc8769d sizeof(text):7 &text:0xbfc8769d sizeof(&text):4 text+1:0xbfc8769e &text+1:0xbfc876a4 What makes me feel confused are: why the value of 'sizeof(text)' is 7 whereas 'sizeof(text+2)' is 4 what's the difference between 'text' and '&text'?

  • Is there a way to define a List<> of two elements string array?

    - by Alexander Prokofyev
    I want to build two-dimentional array of strings where length of one dimention is 2. Similar to this string[,] array = new string[,] { {"a", "b"}, {"c", "d"}, {"e", "f"}, {"g", "h"} } Doing List<string[]> list = new List<string[]>(); list.Add(new string[2] {"a", "b"}); list.Add(new string[2] {"c", "d"}); list.Add(new string[2] {"e", "f"}); list.Add(new string[2] {"g", "h"}); list.ToArray(); gives me string[][] but not string[,] array. Just curious, is there some trick to build dynamically string[,] array somehow?

  • php zencart mod - having problems with attributes array

    - by user80151
    I inherited a zencart mod and can't figure out what's wrong. The customer selects a product and an attribute (model#). This is then sent to another form that they complete. When they submit the form, the product and the attribute should be included in the email sent. At this time, only the product is coming through. The attribute just says "array." The interesting part is, when I delete the line that prints the attribute, the products_options_names will print out. So I know that both the product and the products_options_names are working. The attribute is the only thing that is not working right. Here's what I believe to be the significant code. This is the page that has the form, so the attribute should already be passed to the form. //Begin Adding of New features //$productsimage = $product['productsImage']; $productsname = $product['productsName']; $attributes = $product['attributes']; $products_options_name = $value['products_options_name']; $arr_product_list[] = "<strong>Product Name:</strong> $productsname <br />"; $arr_product_list[] .= "<strong>Attributes:</strong> $attributes <br />"; $arr_product_list[] .= "<strong>Products Options Name:</strong> $products_options_name <br />"; $arr_product_list[] .= "---------------------------------------------------------------"; //End Adding of New features } // end foreach ($productArray as $product) ?> Above this, there is another section that has attributes: <?php echo $product['attributeHiddenField']; if (isset($product['attributes']) && is_array($product['attributes'])) { echo '<div class="cartAttribsList">'; echo '<ul>'; reset($product['attributes']); foreach ($product['attributes'] as $option => $value) { ?> Can anyone help me figure out what is wrong? I'm not sure if the problem is on this page or if the attribute isn't being passed to this page. TIA

  • Minimalist array creation in c#

    - by sipwiz
    I've always wanted to be able to use the line below but the C# compiler won't let me. To me it seems obvious and unambiguos as to what I want. myString.Trim({'[', ']'}); I can acheive my goal using: myString.Trim(new char[]{'[', ']'}); So I don't die wondering is there any other way to do it that is closer to the first approach?

  • Problem with Global Array in PHP

    - by Suezy
    Hi guys,, need some help pls.. i have a PHP code here that lets a user send a message to multiple recipients using the "phonebook" (from database) as the main list. I used an array to temporarily hold all the desired recipients for the current user. So I have a two box, with each for displaying. The user will clicks the name from the phonebook lisy and clicks "Add" button to add on the temporary list on the other select box. The problem is, whenever I use the "onChange" function in javascript; the array accepts only one recipients, and when I try to add, it replaces the first one. :( Here is my code: $recipients = array(); // How do I place the array here? function reload_page(){ i=document.maillinglist.firstletter.selectedIndex; this.location='./group_msg.php?firstletter='+document.maillinglist.firstletter.options[i].value; } function add(){ } $conn = pg_connect("host=localhost user=sa dbname=messaging"); if(isset($_GET['firstletter'])){ $letter=$_GET['firstletter']; } else { $letter='a';} print ""; print "GROUP MESSAGE"; print ""; print ""; print ""; print ""; for($chr_loop=97;$chr_loop<=122;$chr_loop++){ $alphabet = chr($chr_loop); # Displays list of users arranged by letters - this works fine if($alphabet==$letter){ print "\t\t<option value='$alphabet' selected>-------------------- $alphabet --------------------</option>\n"; } else { print "\t\t<option value='$alphabet'>-------------------- $alphabet --------------------</option>\n";} } print ""; print "<td><select style='width:210px' name=\"non_members[]\" size=10 width=200>"; $sql = "select name from test_phonebook where name like '$letter%';"; $result = pg_query($conn, $sql); # Display users from phonebook using the letter chosen while($row = pg_fetch_assoc($result)){ $my_name = $row['name']; print "<option width=200 value=\"$my_name\">$my_name</option>"; } print "</td>"; print "</select>"; print "<td><input type=submit name=add value=\"->>\" onClick=\"add()\"><br><input type=submit name=del value=\"<<-\"></td>"; print "<td><select name=\"members[]\" style='width:210px' size=10>"; # Display temporary recipients - problem: ONLY DISPLAYS ONE VALUE while (list ($key, $val) = each ($recipients)) { echo "$key -> $val <br>"; print "<option width=200 value=\"$val\">$val</option>"; } print "</select></table></form>"; My aim here, is to place all recipients that the user desires to an array, without losing the previous value added.

  • Removing Duplicates in an array in C

    - by LuckySlevin
    The question is a little complex. The problem here is to get rid of duplicates and save the unique elements of array into another array with their original sequence. For example : If the input is entered b a c a d t The result should be : b a c d t in the exact state that the input entered. So, for sorting the array then checking couldn't work since I lost the original sequence. I was advised to use array of indices but I don't know how to do. So what is your advise to do that?

  • Trying to match variables in a PHP array

    - by Nick B
    I'm stuck with a php array problem. I've to a webpage that takes values from a URL, and I need to cross reference those values against some values on the page and if they match output a 'yes'. It's an expression engine bodge job. The URL is something like domain.com/page/C12&C14 The C12 and C14 represent different categories. I've taken the last bit of the url, removed the 'C' from the values and then exploded the 12&14 into an array. I print_r the array on the page and it shows: Array ( [0] = 12 [1] = 14 ) So, the values are in the array. Lovely. Now on the page I have an html list which looks like 10 12 14 15 I want to output a YES next to the variables that are current in the array so the ideal output would be: 10 12 - YES 14 - YES 15 I was trying this but it keeps just saying No next to all of them. $currentnumber = 12; foreach ($tharray as $element) { if ($element == $currentnumber) { echo "Yes"; } else { echo "No"; } } I thought that should work, but it's not. I checked and the array and the variable are both stings. I did a strlen() on both to see if they are the same, but $currentnumber outputs '13' and the array variable outputs '2'. Any ideas as to why it's saying 13? Is the variable the wrong type of string - and if so how would I convert it?

  • decode mysql query before returning it to view

    - by stormdrain
    I'm running a query to mysql that returns encrypted data. I'd like, if possible, to decode the results before sending it to the view. It seems like better form to handle the decoding in the controller (or even the model) rather than inside the view. I can't seem to wrap my head around how to do it, though. I was thinking I could iterate through the object, decodode it, and push it to another array that would be sent to the view. Problem with this is I won't know (and need to keep) the indexes of the query. So the query might return something like: [id] => 742 [client_id] => 000105 [last] => dNXcw6mQPaGQ4rXfgIGJMq1pZ1dYAim0 [first] => dDF7VoO37qdtYoYKfp1ena5mjBXXU0K3dDlcq1ssSvCgpOx75y0A== [middle] =>iXy6OWa48kCamViDZFv++K6okIkalC0am3OMPcBwK8sA== [phone] => eRY3zBhAw2H8tKE Any ideas?

    suppose I have a python list or a python 1-d array (represented in numpy). assume that there is a contiguous stretch of elements how can I find the start and end coordinates (i.e. indices) of the stretch of non-zeros in this list or array? for example, a = [0, 0, 0, 0, 1, 2, 3, 4] nonzero_coords(a) should return [4, 7]. for: b = [1, 2, 3, 4, 0, 0] nonzero_coords(b) should return [0, 2]. thanks.

  • Flex Tree with infinite parents and children

    - by Tempname
    I am working on a tree component and I am having a bit of the issue with populating the data-provider for this tree. The data that I get back from my database is a simple array of value objects. Each value object has 2 properties. ObjectID and ParentID. For parents the ParentID is null and for children the ParentID is the ObjectID of the parent. Any help with this is greatly appreciated. Essentially the tree should look something like this: Parent1 Child1 Child1 Child2 Child1 Child2 Parent2 Child1 Child2 Child3 Child1 This is the current code that I am testing with: public function setDataProvider(data:Array):void { var tree:Array = new Array(); for(var i:Number = 0; i < data.length; i++) { // do the top level array if(!data[i].parentID) { tree.push(data[i], getChildren(data[i].objectID, data)); } } function getChildren(objectID:Number, data:Array):Array { var childArr:Array = new Array(); for(var k:Number = 0; k < data.length; k++) { if(data[k].parentID == objectID) { childArr.push(data[k]); //getChildren(data[k].objectID, data); } } return childArr; } trace(ObjectUtil.toString(tree)); } Here is a cross section of my data: ObjectID ParentID 1 NULL 10 NULL 8 NULL 6 NULL 4 6 3 6 9 6 2 6 11 7 7 8 5 8
