application programming interface code example
Example 1: what is api
An application program interface (API) is a set of routines, protocols, and
tools for building software applications.
Basically, an API specifies how software components should interact.
Additionally, APIs are used when programming graphical user interface (GUI)
components.
A good API makes it easier to develop a program by providing all the
building blocks. A programmer then puts the blocks together.
Example 2: api
An application programming interface is a computing interface which defines
interactions between multiple software intermediaries.
It defines the kinds of calls or requests that can be made, how to make them,
the data formats that should be used, the conventions to follow, etc.
Example 3: what is api
API (Application Programming Interface) helps in communication
and data exchange between two software systems. It is the channel which
connects two software systems communicate with one another.
An API forms the middle layer of a three-layered application pyramid,
consisting of a data layer, a server layer and a presentation layer.
While the data layer is concerned with data storage and the presentation
layers are concerned with the user interface, the server layer is composed
of business logic that defines the way for users to interact with various
functions, features, and information.
RESTful API ==> plain text, html, xml, json
SOAP ==> more secure, works with only xml
Example 4: what is api
API : Application Programming Interface
An api is a particular set of rules and specifications that programs can
follow to communicate with each other .
The end user sends request , API executes instructions then get the data
from the server and responds to the user.
Example 5: where do you use interface
Interfaces specify what a class must do.
It is the blueprint of the class.
It is used to achieve total abstraction.
We are using implements keyword for interface.
Basic statement we all know in Selenium is
WebDriver driver = new FirefoxDriver();
WebDriver itself is an Interface.
So we are initializing Firefox browser
using Selenium WebDriver.
It means we are creating a reference variable
of the interface and creating an Object.
So WebDriver is an Interface and
FirefoxDriver is a class.
Example 6: interface
Interfaces specify what a class must do.
It is the blueprint of the class.
It is used to achieve total abstraction.
We are using implements keyword for interface.
Basic statement we all know in Selenium is
WebDriver driver = new FirefoxDriver();
WebDriver itself is an Interface.
So we are initializing Firefox browser
using Selenium WebDriver.
It means we are creating a reference variable
of the interface and creating an Object.
So WebDriver is an Interface and
FirefoxDriver is a class.
