About this course

Linear data structures like arrays and lists only go so far when modeling real-world relationships like social networks, folder structures, or hierarchical data. To build efficient, scalable software, you must know how to organize and manipulate data non-linearly. This text-based course guides you from foundational concepts to implementing sophisticated data structures in Java. You will learn how to analyze, design, and write clean Java code for trees, graphs, and hash-based structures, utilizing modern Java conventions. What you'll learn: - Understand the core concepts of non-linear data organization and algorithmic complexity. - Implement binary trees, binary search trees, and explore self-balancing tree concepts. - Represent complex networks using graph data structures and fundamental traversal algorithms. - Apply modern Java features, such as records, to design clean and immutable node structures. - Utilize Java's built-in Collections Framework, including Map and Set interfaces, for efficient data lookup. - Practice solving structural programming problems through written code analysis and exercises. The course starts with essential terminology and the mathematical foundations of hierarchical data before moving into step-by-step code implementations. You will follow logical written explanations and complete structured practice exercises designed to solidify your conceptual understanding. This course is designed for beginner Java programmers who want to transition from basic syntax to advanced data organization; no prior knowledge of algorithms is required.
