Java EE (Java Enterprise Edition) is a platform that allows developers to create and deploy enterprise-level, scalable applications. It includes a set of APIs (Application Programming Interfaces) and technologies for building web-based, distributed applications that can handle high traffic and large amounts of data. Java EE applications can run on a variety of servers, offer high performance and reliability, and are portable across different environments. Developing and managing Java EE applications require specialized skills in coding, testing, deployment, and maintenance.
