If you want to add a UIImageView to the center of the screen with width and height of 100 pixel, you need to set center x constraint and center y constraint to the superview from the UIImageView and width, height constraint to the UIIMageView. Here is the code. There is way to do this in storyboard ...
A NullReferenceException is thrown when you try to access a non-static member (property, method, field or event) of a reference object but it is null.
Car myFirstCar = new Car();
Car mySecondCar = null;
Color myFirstColor = myFirstCar.Color; // No problem as myFirstCar exists / is not null

The ROW_NUMBER function can assign an incrementing number to each row in a result set. Combined with a Common Table Expression that uses a BETWEEN operator, it is possible to create 'pages' of result sets. For example: page one containing results 1-10, page two containing results 11...
There are two equivalent ways to calculate the amount of time unit between two LocalTime: (1) through until(Temporal, TemporalUnit) method and through (2) TemporalUnit.between(Temporal, Temporal).

Parallelism in Haskell can be expressed using the Eval Monad from Control.Parallel.Strategies, using the rpar and rseq functions (among others).
f1 :: [Int]
f1 = [1..100000000]
f2 :: [Int]
f2 = [1..200000000]
main = runEval $ do
a <- rpar (f1) -- this'll take a while...

Cast your random floating-point number as an int.
Input:
my $range = 10;
# create random integer as low as 0 and as high as 9
my $random = int(rand($range)); # max value is up to but not equal to $range
print $random . "\n";
Output:
A random integer, like...

Let's understand something. JavaEE consists of a number of specifications. When you install an Application Server (Payara for example), you install all of the specifications at once. For example there's a specification for an ORM called JPA (Java Persistence API), a specification to build Component ...
We will present some examples to show how to apply happens-before reasoning to check that writes are visible to subsequent reads.

CALL is also a way to extend COBOL functionality, and also to allow the reusability of code. It can also give access to "system" functionality.
This example illustrates ways to provide "sleep" functionality to IBM Mainframe COBOLs. Bear in mind that the requirement to do so is r...

A decision tree is a classifier which uses a sequence of verbose rules (like a>7) which can be easily understood.
The example below trains a decision tree classifier using three feature vectors of length 3, and then predicts the result for a so far unknown fourth feature vector, the so called te...
