They are used primarily for collections such as HashSet, HashMap, and Hashtable to store and retrieve objects based on their hash codes and to check for object equality. What is new in this class, are hashCode() and equals() methods that are used to define object equality and hash values. public interface IEmployee įinally, our last class, named Address class includes information about the location of every company. Let’s define a new interface named as IEmployee. *Inversion of control container - This is the core of the Spring Framework where objects are created, wired together, configured, and managed throughout their life cycle.Concepts of Object Oriented Programming used:Ĭreate a new java project in Eclipse or IntelliJ. *Inversion of control (IoC) - Taking control away from the class and giving it to the Spring Framework. *Dependency injection - A programming design pattern that makes code loosely coupled, meaning that any change in the application will not affect the other.
Beans are the backbone of an application. *Bean - A Spring bean is an object that is instantiated, created, and managed by the IoC container. Why Spring? *Autowiring - The process by which Spring identifies dependencies and matches and populates them. That extension includes pre-configurable web starter kits that help facilitate the responsibilities of an application server that are required for other Spring projects. *What is Spring Boot? Spring Boot is just an extension of the already existing and expansive Spring frameworks, but it has some specific features that make the application easier for working within the developer ecosystem. Spring improves coding efficiency and reduces overall application development time because it is lightweight, efficient at utilizing system resources, and has a lot of support. Spring is a secure, low-cost and flexible framework. *What is Spring? The Spring Framework (Spring) is an open-source application framework that provides infrastructure support for developing Java applications. Here are some terms which I emphasized before getting started with the project. The data received from the user (HR admin) will be stored in database and retrieved when required. This research made me choose spring and spring-boot while developing the project. Employee Management System Abstract: Create a console based Java application that would allow the HR admin of a company to add / modify / view information of an Employee as per the design specifications given below. While going through the tutorials and available content on the web, I got to know complex spring terms and their implementation.
^Preferred using SpringToolSuite(STS) for coding. ^I have used MySQL for database management.
