I think the issue was by ths following , trying to create string array from key/value below code returns key/value. How do I create string array? , You can use map to achieve the same.
code :
const array = [
  {"id":"123"},
  {"id":"124"}
]

console.log(array.map(item => item.id))

I hope this helps . Let's say I have array like {"12","23","","34","22","","","12"}
code :
var yourArray = ...;
yourArray = yourArray.Where(str => !string.IsNullOrWhiteSPace(str)).ToArray();

var yourResult = Enumerate

Android dynamically create String Array from XML string resources, without XML string array

I wish this helpful for you Ok, so this question is a bit weird, and kinda rubs me the wrong to even ask, but since I probably don't have a choice I want to see what you guys think. I'm still a novice at Java and Android. , So you will get strings.xml as below
code :
<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="string1">1st string</string>
    <string name="string2">2nd string</string>
                 ........
    <string name="stringN">Nth string</string>
</resources>
<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="count">4</string>
    <string name="prefix">string</string>
    <string name="string1">1st string</string>
    <string name="string2">2nd string</string>
    <string name="string3">3rd string</string>
    <string name="string4">4th string</string>
</resources>
int count = Integer.parseInt(getString(R.string.count));
        String prefix = getString(R.string.prefix);
        String[] strings = new String[count];
        for (int i = 0; i < count; i++) {
            strings[i] = getString(getResources().getIdentifier(prefix+(i+1), "string", getPackageName()));
        }

around this issue I'm not sure how to better phrase my question, but here is my situation. , Try this:
code :
$temp_array = array("111111-Name1-122874|876394|120972", "222222-Name2-122874|876394|120972", "333333-Name3-122874|876394|120972");
$id          = "222222";
$rand_number = "999888";

// Loop over each element of the array
// For each element, $i = the key, $arr = the value
foreach ($temp_array as $i => $arr){

    // Get the first characters of the element up to the occurrence of a dash "-" ...
    $num = substr($arr, 0, strpos($arr, '-'));

    // ...and check if it is equal to $id...
    if ($num == $id){
        // ...if so, add $random_number to the back of the current array element
        $temp_array[$i] .= '|'  . $rand_number;
    }
}
Array
(
    [0] => 111111-Name1-122874|876394|120972
    [1] => 222222-Name2-122874|876394|120972|999888
    [2] => 333333-Name3-122874|876394|120972
)

C# - Split string into an array of string using RegEx and create a dictionary<string,string>

I hope this helps you . It would be simpler to use Regex.Matches chained with Linq to get the dictionary directly :
code :
var input = "[Key1,Value1][Key2,Value2][Key3,Value3][Key4,Value4]";

var dictionary = Regex.Matches(input, @"\[(?<key>\w+),(?<value>\w+)\]")
    .Cast<Match>()
    .ToDictionary(x => x.Groups["key"].Value, x => x.Groups["value"].Value);

Create a char array for every string inside a string array


By : Laxman Patil

around this issue I'm trying to implement in java this little project: I want to rename the episodes of an entire season in a series using a text file that has the names of all the episodes in that season. To that end I wrote a code that reads the text file and stores every line of text (the name of an episode) as a string array, where every element of the array stores the name of one episode. Also, I wrote a code that takes the FIRST element of that array (an array called arrayLines[]) and renames a given file. This code works like a charm. What I want to do next is to create a char array for every element in the string array arrLines[]. The pseudo-code i'm thinking to implement is something like this: , Just use a 2-dimensional char array:
code :
char[][] lines = new char[arrLines.length][];
for (int i = 0; i < arrLines.length; i++) {
    lines[i] = arrLines[i].toCharArray();
}
char[][] lines = Arrays.stream(arrLines)
        .map(String::toCharArray)
        .toArray(char[][]::new);
