Learn Core Java from Scratch - Hands-On Training - 2026

This course features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. Take your Java programming expertise to the next level by mastering advanced language features and modern concurrency techniques used in enterprise-grade applications. This course equips you with the skills to write scalable, maintainable, and high-performance Java programs through generics, file handling, serialization, multithreading, synchronization, and concurrent programming frameworks. You will gain practical knowledge that strengthens your ability to build robust backend systems and optimize application performance. The course begins with advanced Java concepts such as generics and enumerations, helping you create reusable, type-safe, and cleaner code structures. You will explore practical implementations of generic classes and methods while learning how to avoid common pitfalls developers face when using generics. The course then introduces Java IO and file handling concepts, including input/output streams, serialization, and efficient data processing techniques used in real-world applications. As the course progresses, you will dive deeply into multithreading and concurrency. You will learn thread creation and management, synchronization, thread communication, interruption handling, thread pools, atomic variables, and thread-local storage. Advanced frameworks such as Executor and Fork/Join will help you understand how modern Java applications handle parallel task execution efficiently and safely. This course is ideal for intermediate Java learners, software developers, backend engineers, and students seeking to strengthen their understanding of concurrent programming and advanced Java development. Learners should have prior knowledge of core Java concepts, object-oriented programming, and basic application development. The difficulty level of this course is Intermediate. By the end of the course, you will be able to design reusable generic components, manage file operations and serialization, implement safe multithreaded applications, and utilize advanced concurrency frameworks to improve application performance and scalability.

A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. Dive into the fundamentals of Java and gain practical skills to build efficient, scalable programs. This course empowers you to understand core programming concepts, explore data types, control structures, and object-oriented principles while strengthening problem-solving abilities.
