Almost sure to be asked in every company using any Dependency Injection framework ( Spring, Guice etc )
  Q1. What is Dependency Injection or IOC ( Inversion of Control ) ?Design

Ans. It is a Design Pattern that facilitates loose coupling by sending the dependency information ( object references of dependent object ) while building the state of the object. Objects are designed in a manner where they receive instances of the objects from other pieces of code, instead of constructing them internally and hence provide better flexibility.

 Q2. What is the difference between SDLC and Agile ?Process2017-08-28 19:37:08

Ans. Here are the differences between Agile and Waterfall Methodology:

The software development process is divided into different phases in the Waterfall model while Agile methodology segregates the project development lifecycle into sprints

Waterfall is a structured software development methodology, and often times can be quite rigid, whereas the Agile methodology is known for its flexibility

According to the Waterfall model, software development is to be completed as one single project, which is then divided into different phases, with each phase appearing only once during the SDLC. However, the Agile methodology can be considered as a collection of many different projects, which are nothing but the iterations of the different phases focusing on improving the overall software quality with feedback from users or the QA team

If you want to use the Waterfall model for software development, then you have to be clear with all the development requirements beforehand as there is no scope of changing the requirements once the project development starts. The Agile methodology, on the other hand, is quite flexible, and allows for changes to be made in the project development requirements even after the initial planning has been completed

All the project development phases such as designing, development, testing, etc. are completed once in the Waterfall model while as part of the Agile methodology, they follow an iterative development approach.

As a result, planning, development, prototyping and other software development phases can appear more than once during the entire SDLC One of the major differences between Agile and Waterfall development methodology is their individual approach towards quality and testing.

In the Waterfall model, the Testing phase comes after the Build phase, but, in the Agile methodology, testing is typically performed concurrently with programming or at least in the same iteration as programming

While Waterfall methodology is an internal process and does not require the participation of customers, the Agile software development approach focuses on customer satisfaction and thus, involves the participation of customers throughout the development phase

The Waterfall model can be regarded as a stringently sequential process, however, the Agile methodology is a highly collaborative software development process, thereby leading to better team input and faster problem solving

The Waterfall model is best suited for projects which have clearly defined requirements and in which change is not expected at all, while Agile development supports a process in which the requirements are expected to change and evolve. Thus, if you are planning to develop a software that would require frequent overhauls and has to keep up with the technology landscape and customer requirements, Agile is the best approach to follow

The Waterfall model exhibits a project mindset and lays its focus strictly on the completion of project development, while Agile introduces a product mindset that focuses on ensuring that the developed product satisfies its end customers, and changes itself as the requisites of customers change
