Specialization - 3 course series

This specialization prepares learners for the Oracle Certified Professional (OCP) Java SE 21 exam, progressing from foundational Java concepts to advanced application development techniques.

In the first course, learners will cover essential Java syntax, core APIs, and control flow concepts, providing a solid foundation for writing maintainable Java code.

The second course focuses on object-oriented programming (OOP) and functional programming techniques, with deep dives into lambdas, functional interfaces, and collections.

In the final course, learners will explore advanced Java SE 21 topics, including streams, modules, concurrency, and I/O, enabling them to tackle real-world Java applications. By the end of the specialization, learners will not only be prepared for the OCP exam but also gain valuable skills for professional Java development.
