What are Core Java developers?

Core Java developers are software professionals who specialize in building applications using the fundamental features and libraries of the Java programming language. They focus on core concepts such as object-oriented programming, data structures, multithreading, exception handling, and the Java API. Core Java is the foundation for other Java technologies like Java EE, and developers in this role often create desktop, server-side, or foundational components of larger systems. Their expertise is critical in ensuring robust, scalable, and maintainable Java applications.
