This problem is pretty debuggable, an uncommon luxury when you have problems with threads. Your basic tool here is the Debug > Windows > Threads debugger window. Shows you the active threads and gives you a peek at their stack trace. You’ll easily see that, once it gets slow, that you’ll have dozens of threads … Read more
If you want an Iterator over an array, you could use one of the direct implementations out there instead of wrapping the array in a List. For example: Apache Commons Collections ArrayIterator Or, this one, if you’d like to use generics: com.Ostermiller.util.ArrayIterator Note that if you want to have an Iterator over primitive types, you … Read more
Put your values in an array and then implode that array with a comma (+ a space to be cleaner): $myArray = array(); foreach ($this->sinonimo as $s){ $myArray[] = ‘<span>’.ucfirst($s->sinonimo).'</span>’; } echo implode( ‘, ‘, $myArray ); This will put commas inbetween each value, but not at the end. Also in this case the comma … Read more
Try this: foreach($samplearr as $key => $item){ print “<tr><td>” . $key . “</td><td>” . $item[‘value1’] . “</td><td>” . $item[‘value2’] . “</td></tr>”; }
There are several places colon is used in Java code: 1) Jump-out label (Tutorial): label: for (int i = 0; i < x; i++) { for (int j = 0; j < i; j++) { if (something(i, j)) break label; // jumps out of the i loop } } // i.e. jumps to here 2) … Read more
You can access your array keys like so: foreach ($array as $key => $value)
Two ways, you can alter the memory location shared by the current value directly, or access the value using the source array. // Memory reference foreach ($bizaddarray as &$value) { $value = strip_tags(ucwords(strtolower($value))); } unset($value); # remove the reference Or // Use source array foreach ($bizaddarray as $key => $value) { $bizaddarray[$key] = strip_tags(ucwords(strtolower($value))); }
It’s perfectly possible to write a ForEach extension method for IEnumerable<T>. I’m not really sure why it isn’t included as a built-in extension method: Maybe because ForEach already existed on List<T> and Array prior to LINQ. Maybe because it’s easy enough to use a foreach loop to iterate the sequence. Maybe because it wasn’t felt … Read more
foreach is a read only iterator that iterates dynamically classes that implement IEnumerable, each cycle in foreach will call the IEnumerable to get the next item, the item you have is a read only reference, you can not re-assign it, but simply calling item.Value is accessing it and assigning some value to a read/write attribute … Read more
Lets see why JavaScript behaves like this. According to the ECMAScript standard specification for Array.prototype.forEach, when you delete an element at index 1, the element at index 2 becomes the element at index 1 and index 2 doesn’t exist for that object. Now, JavaScript looks for element 2 in the object, which is not found, … Read more
