Why learn Java?

Java is a general-purpose, class-based, object-oriented computer programming language that was designed by James Gosling at Sun Microsystems in 1995.

Key Highlights of Java:
Platform Independent: This allows programmers to develop applications that can run on any operating system.

Usability of Java: Java is most widely used programming language. It is present everywhere. It really doesn't matter which domain you are working in, you will surely come across Java sooner or later!

Open Source: The good news is that Java is available for free! All the development tools and the environment (JRE & JDK) that is used to develop Java applications are absolutely free of cost.

Android: Irrespective of the fact that you are tech savvy or not, most of us are badly bitten by the Android bug! Android is in great demand today and fortunately you need Java for Android development. Hence, the importance of Java has increased even more.

Hadoop: Hadoop is one of the most trending framework for processing Big Data. It has been designed and developed in Java.

In spite of having a tough competition on the server side from Microsoft and other companies, Java is doing extremely well on mobile platforms, thanks to Android! It has also been the primary language for Hadoop Developers.

Understand the Difference Between SOAP and REST APIs

Simple Object Access Protocol (SOAP) and Representational State Transfer (REST) are two answers to the same question: how to access Web services. The choice initially may seem easy, but at times it can be surprisingly difficult. Learn more about SOAP vs REST here:

Effective Design of RESTful APIs

Mohamed Taman, Sr. Enterprise Architect / Sr. Software Engineer, WebCentric

Developers creating websites, especially back-end developers, need to know how to build RESTful APIs correctly. Nowadays those APIs are serving many channels: mobile, microservices components, IoT, integration, or all of these. This session will help you plan and model your own APIs and understand security and the six REST design constraints that help guide your architecture. It starts with a simple overview, including advice on identifying the participants in your system and the activities they might perform with it. The presenter will help you paper-test your model, validating the design before you build it and providing a live example to make sure the concept is clear. Finally the session explores the HTTP concepts and REST constraints needed to build your API.

APIs | REST | REST APIs Demystified

Hey fellow developers!
In this video, I tried to explain in details what an API is? How does it relate to web service? How does it relate to REST?
I also explain REST (REpresentational State Transfer). I explain how the concept relates to the WEB and to HTTP.
After that I talked about How RESTful APIs work with diagram and code. Finally, I give a short list of what you need to know to start building APIs.
I know the video is sort of long, but I think it is worth your time. I hope there was a video like this when I first wanted to learn about API and REST. And this is probably why I created it. I know the pain, and I don't want you to go through it. Enjoy! :)

My two favorite books about RESTful APIs:

Coding 101 Introduction to REST APIs

A classroom session from the DevNet Zone at Cisco Live Berlin 2017. Do you want to get started using APIs and automation? A wide range of Cisco platforms such as APIC-EM, ACI, NX-API, Cisco Spark and many more expose REST APIs. The goal of this session is to introduce attendees to the basics of using REST APIs in an application, and to provide them with the skills to start engaging in this growing area. Watch this video to learn about the concepts you need to create applications that consume REST APIs.

What is an API?

What exactly is an API? Finally learn for yourself in this helpful video from MuleSoft, the API experts.

The textbook definition goes something like this:

“An application programming interface (API) is a set of routines, protocols, and tools for building software applications. An API expresses a software component in terms of its operations, inputs, outputs, and underlying types. An API defines functionalities that are independent of their respective implementations, which allows definitions and implementations to vary without compromising each other. A good API makes it easier to develop a program by providing all the building blocks.

APIs often come in the form of a library that includes specifications for routines, data structures, object classes, and variables. In other cases, notably SOAP and REST services, an API is simply a specification of remote calls exposed to the API consumers.

An API specification can take many forms, including an International Standard, such as POSIX, vendor documentation, such as the Microsoft Windows API, or the libraries of a programming language, e.g., the Standard Template Library in C++ or the Java APIs.

An API differs from an application binary interface (ABI) in that an API is source code-based while an ABI is a binary interface. For instance POSIX is an API, while the Linux Standard Base provides an ABI”.

To speak plainly, an API is the messenger that runs and delivers your request to the provider you’re requesting it from, and then delivers the response back to you.

To give you a familiar example, think of an API as a waiter in a restaurant.

Imagine you’re sitting at the table with a menu of choices to order from, and the kitchen is the provider who will fulfill your order.

What’s missing is the critical link to communicate your order to the kitchen and deliver your food back to your table.

That’s where the waiter (or API) comes in. ”AHEM”

The waiter takes your order, delivers it to the kitchen, and then delivers the food (or response) back to you. (Hopefully without letting your order crash if designed correctly)


Now that we’ve whetted your appetite, let’s apply this to a real API example. In keeping with our theme, let’s book a flight to a culinary capital – Paris.


You’re probably familiar with the process of searching for airline flights online. Just like at a restaurant, you have a menu of options to choose from ( a dropdown menu in this case). You choose a departure city and date, a return city and date, cabin class, and other variables (like meal or seating, baggage or pet requests)

In order to book your flight, you interact with the airline’s website to access the airline’s database to see if any seats are available on those dates, and what the cost might be based on certain variables.


But, what if you are not using the airline’s website, which has direct access to the information? What if you are using online travel service that aggregates information from many different airlines? Just like a human interacts with the airline’s website to get that information, an application interacts with the airline’s API.


The API is the interface that, like your helpful waiter, runs and and delivers the data from that online travel service to the airline’s systems over the Internet.

It also then takes the airline’s response to your request and delivers right back to the online travel service .

And through each step of the process it facilitates that interaction between the travel service and the airline’s systems - from seat selection to payment and booking.

So now you can see that it’s APIs that make it possible for us all to use travel sites. They interface with with airlines’ APIs to gather information in order to present options back to us

The same goes for all interactions between applications, data and devices - they all have API’s that allow computers to operate them, and that's what ultimately creates connectivity.

API’s provide a standard way of accessing any application, data or device whether it is shopping from your phone, or accessing cloud applications at work.

So, whenever you think of an API, just think of it as your waiter running back and forth between applications, databases and devices to deliver data and create the connectivity that puts the world at our fingertips. And whenever you think of creating an API, think MuleSoft.

REST API with JSON-Server | REST API Concepts and examples

Capture & Edit : Shahittik Purno.
#Rest_API
#HTTP
#API
In this video I am going to show you how to install a fake REST API using an incredible tool called JSON-Server. This is used for mocking and prototyping and is something that I personally use all of the time. It is useful to anyone building frontend apps with something like Angular, React, etc.

Developing an API in many web application or other application platform you need to develop a custom API service for several application. That's why you need an external JSON server to host your JSON data.

This video introduces the viewer to some API concepts by making example calls to Facebook's Graph API, Google Maps' API, Instagram's Media Search API, and Twitter's Status Update API.
