Code that uses generics has many benefits over non-generic code. Below are the main benefits
Stronger type checks at compile time
A Java compiler applies strong type checking to generic code and issues errors if the code violates type safety. Fixing compile-time errors is easier than fixing runt...
Different operations with data are done using special classes.
Most of the classes belong to one of the following groups:
classification algorithms (derived from sklearn.base.ClassifierMixin) to solve classification problems
regression algorithms (derived from sklearn.base.RegressorMixin) to so...
A Service is a component which runs in the background (on the UI thread) without direct interaction with the user. An unbound Service is just started, and is not bound to the lifecycle of any Activity.
To start a Service you can do as shown in the example below:
// This Intent will be used to star...
A callback is a method that gets called at specific moments of an object's lifecycle (right before or after creation, deletion, update, validation, saving or loading from the database).
For instance, say you have a listing that expires within 30 days of creation.
One way to do that is like this:

When it comes to geographic data, R shows to be a powerful tool for data handling, analysis and visualisation.
Often, spatial data is avaliable as an XY coordinate data set in tabular form. This example will show how to create a spatial data set from an XY data set.
The packages rgdal and sp provi...
A method defined in an interface is by default public abstract. When an abstract class implements an interface, any methods which are defined in the interface do not have to be implemented by the abstract class. This is because a class that is declared abstract can contain abstract method declaratio...
interface ITable {
// an indexer can be declared in an interface
object this[int x, int y] { get; set; }
}
class DataTable : ITable
{
private object[,] cells = new object[10, 10];
/// <summary>
/// implementation of the indexer declared in the interface

A static member function is just like an ordinary C/C++ function, except with scope:
It is inside a class, so it needs its name decorated with the class name;
It has accessibility, with public, protected or private.
So, if you have access to the static member function and decorate it correctl...
To access a member function of a class, you need to have a "handle" to the particular instance, as either the instance itself, or a pointer or reference to it. Given a class instance, you can point to various of its members with a pointer-to-member, IF you get the syntax correct! Of course...

Prefabs are an asset type that allows the storage of a complete GameObject with its components, properties, attached components and serialized property values. There are many scenarios where this is useful, including:
Duplicating objects in a scene
Sharing a common object across multiple scenes

Each pair in the dictionary is an instance of KeyValuePair with the same type parameters as the Dictionary. When you loop through the dictionary with For Each, each iteration will give you one of the Key-Value Pairs stored in the dictionary.
For Each kvp As KeyValuePair(Of String, String) In curren...
