Java EE (Jakarta EE)

Java EE (now called Jakarta EE) is a set of standardized tools and technologies that help developers build large-scale, reliable web applications and enterprise systems using Java. It provides frameworks for managing data, security, transactions, and web interfaces, enabling applications to handle complex business logic smoothly. Think of it as a blueprint and toolkit that ensures different parts of an enterprise application work together consistently, scalable, and securely. This makes Java EE fundamental for developing robust, enterprise-level software used in banking, airlines, and large organizations worldwide.
