About this course

Preparing for technical interviews can feel overwhelming when you have to learn a programming language and complex algorithms at the same time. This structured text-based course guides you step-by-step from writing your first line of Java to solving algorithmic challenges with confidence. You will transition from a coding beginner to a methodical problem solver. By reading clear explanations, studying structured code examples, and working through written exercises, you will build a deep understanding of how to write efficient Java code and apply the right data structures to solve computational problems. What you'll learn: - Understand foundational Java syntax, object-oriented programming principles, and modern features like records and local variable type inference. - Analyze algorithm efficiency using Big O notation to write optimized, high-performance code. - Implement essential data structures from scratch, including arrays, linked lists, stacks, queues, and trees. - Apply powerful algorithmic techniques such as recursion, sorting, searching, and two-pointer approaches. - Solve popular LeetCode-style coding challenges systematically using step-by-step mental frameworks. - Practice debugging and dry-running code on paper to build strong analytical skills for technical interviews. The course starts with core Java concepts and basic syntax, ensuring a solid foundation before moving into object-oriented design. From there, you will explore data structures, algorithmic paradigms, and practical strategies for breaking down complex coding problems. This course is designed for beginners with no prior programming experience, as well as self-taught developers looking to strengthen their computer science fundamentals and interview readiness. Start reading today to master Java and build the problem-solving skills needed to succeed in your technical journey.
