Java Enterprise Edition (Java EE) is a set of specifications that extend the Java Platform to support large-scale, multi-tiered, and distributed applications. It provides a robust framework for developing enterprise-level applications, offering features like servlets, JavaServer Pages (JSP), and Enterprise JavaBeans (EJB) to simplify the development process. Java EE promotes best practices in software development, including modularity and scalability. It includes a variety of APIs for tasks such as web services, messaging, and persistence, making it easier for developers to build secure and efficient applications that can handle high loads and complex transactions.
