Q What are the components of web service?

Web Service Components:
===========================
There are three major web service components.
1. SOAP--Simple Object Access Protocol
2. WSDL-Web Service Description language
3. UDDI--Universal Description, Discovery, and Integration
4.XML- Extensible Markup Language

SOAP
==================
-> SOAP is an acronym for Simple Object Access Protocol.
-> SOAP is a XML-based protocol for accessing web services.
-> SOAP is a W3C recommendation for communication between applications.
-> SOAP is XML based, so it is platform independent and language independent. In other words, it can be used with Java, .Net or PHP language on any platform.

WSDL
=======================
-> WSDL is an acronym for Web Services Description Language.
-> WSDL is a xml document containing information about web services such as method name, method parameter and how to access it.
-> WSDL is a part of UDDI. It acts as a interface between web service applications.
-> WSDL is pronounced as "wiz-dull".

UDDI
====================
-> UDDI is an acronym for Universal Description, Discovery and Integration.
-> UDDI is a XML based framework for describing, discovering and integrating web services.
-> UDDI is a directory of web service interfaces described by WSDL, containing information about web services.

Mockito interview Questions

1.       Question 1. What Is Mockito? Answer : Mockito allows creation of mock object for the purpose of Test Driven Development and Behavior Driven development. Unlike creating actual object, Mockito allows creation of fake object (external dependencies) which allows it to give consistent results to a given invocation. 2.       Question 2. Why Do We Need Mockito? What Are The Advantages? Answer : Mockito differentiates itself from the other testing framework by removing the expectation beforehand. So, by doing this, it reduces the coupling. Most of the testing framework works on the "expect-run-verify". Mockito allows it to make it "run-verify" framework. Mockito also provides annotation which allows to reduce the boilerplate code. 3.       Question 3. Can You Explain A Mockito Framework? Answer : In Mockito, you always check a particular class. The dependency in that class is injected using m...

REST Methods

GET ============================================= HTTP GET method is used to **read** (or retrieve) a representation of a resource. According to the design of the HTTP specification, GET requests are used only to read data and not change it. Therefore, when used this way, they are considered safe. That is, they can be called without risk of data modification or corruption. Means calling it once has the same effect as calling it 10 times. Additionally, GET is idempotent which means that making multiple identical requests ends up having the same result as a single request. Donot expose unsafe operations via GET. It should never modify any resources on the server. Example: ------------    GET http://www.example.com/customers/12345/orders POST =================================== -> The POST verb is most-often utilized to **create** new resources. In particular, it's used to create subordinate resources. -> That is, subordinate to some other (e.g. parent) reso...
