Java development

Java is an object-oriented programming language created by Sun Microsystems employees James Gosling and Patrick Naughton, with the support of Bill Joy (co-founder of Sun Microsystems in 1982), and officially presented at SunWorld on May 23, 1995. In 2009, Sun was acquired by Oracle, which now owns and maintains Java.

Spring Framework

Spring is a foundation for the development of applications, mainly but not necessarily for enterprises. It provides numerous functionalities that are sometimes redundant, or that can be configured or used in several ways: this leaves developers free to choose the solution that suits them best and/or meets their needs.

Spring is thus one of the most widespread frameworks in the Java world: its popularity has grown thanks to the complexity of Java EE, particularly for versions prior to version 5, but also thanks to the quality and richness of the features it offers:

its core, based on an IoC container, ensures bean lifecycle management and dependency injection
use of AOP
projects to facilitate integration with numerous open source projects and Java EE APIs.
Spring started out as an application framework, but is now a true platform, comprising the Spring framework, projects covering a wide range of needs, and middleware.
