What does SDLC stand for in software engineering? Why do we need to pay attention to it?

Describe the difference between class and object in Java.

Solution

SDLC is a well-defined, structured sequence of stages in software engineering to develop the intended software product. SDLC framework includes these important steps: communication, requirement gathering, feasibility study, system analysis, software design, coding, testing, integration, implementation, operations and maintenance, disposition.

We need to pay attention to it during software development process due to following reasons :-

-> It describes all the phases that a prgram developer or team has to follow to ensure success.

-> SDLC is important because it breaks down the entire life cycle of software devvelopment thus make it easier to evaluate each part of software development.

-> SDLC makes it easier for programmers to work concurrently on each phase. Also, provides a rough time when software will be available for use.

-> SDLC serves as a guide to the project and provides a flexible and consistent medium to accommodate changes, and perform the project to meet client’s objectives.

-> SDLC phases define key schedule and delivery points which ensure timely and correct delivery to the client within budget and other constraints and project requirements.

-> SDLC co-operates project control and management activities as they must be introduced within each above mentioned phases of SDLC.

-> Without SDLC, there are no documentations to support the development of the program. With an SDLC Model, programs built will have a clear documentation of development, structure and even coding.

Here is the list of differences between Class and Object in Java. Class and Object are related to each other because every Object must be type of any class. In the same time class itself is of no use until we create object. Let’s note down the difference between class and object in points :

Object can be created many time as per our requirement but Class is created only once.
