Java is a programming language widely used in the development of computer applications and systems. However, many developers may have questions about the differences between the two major versions of the language: Java SE and Java EE. While both share similarities, they also present important differences that are crucial to take into account when choosing the right version for a specific project. In this article, we will explore the fundamental differences between Java SE and Java EE to help you better understand each one and make informed decisions when developing your applications.

Step by step -- What are the differences between Java SE and Java EE?

• Java SE (Standard Edition) and Java EE (Enterprise Edition) are two different Java platforms, designed for specific purposes.
• Java SE is the main platform and basis for all other Java editions, like Java EE.
• Java SE is used to develop desktop applications, web applications and basic web services, while Java EE focuses on the development of more complex enterprise applications.
• Java SE includes a set of basic libraries and APIs which are necessary for most applications, while Java EE includes additional libraries and specialized APIs for business development, such as database access, messaging, and security.
• Java SE does not require an application server to run applications developed with this platformWhile Java EE requires an application server to deploy and run enterprise applications.
• Java SE is suitable for developers working on smaller or individual projectsWhile Java EE is best suited for development teams working on large-scale and complex enterprise projects.
