J2EE/J2SE SWING/SERVLET
J2SE is the core Java platform that provides the fundamental libraries and APIs required to develop standalone, desktop, and basic Java applications. It includes essential features such as object-oriented programming concepts, exception handling, collections, multithreading, file handling, and networking. J2SE forms the foundation for all other Java editions.
J2EE is an enterprise-level Java platform built on top of J2SE and is used to develop large-scale, distributed, and web-based applications. It provides technologies like Servlets, JSP, EJB, JDBC, and web services to support multi-tier architecture, scalability, security, and transaction management.
Swing is a Java GUI toolkit used to create rich, platform-independent desktop applications. It provides a set of lightweight components such as buttons, tables, labels, and text fields to build interactive and user-friendly graphical interfaces.
