About this course

Understanding how data is organized and stored is crucial for writing efficient, professional software. This text-based course guides you through the core concepts of linear data structures and trees using clear, step-by-step Java implementations. You will transition from writing basic scripts to designing optimized algorithms, mastering how arrays, lists, stacks, queues, and trees function under the hood. What you'll learn: - Understand foundational computer science terminology and memory allocation concepts. - Implement linear structures including dynamic arrays, linked lists, stacks, and queues from scratch. - Explore tree architectures, binary search trees, and key traversal algorithms. - Apply modern Java features like generics and records to write clean, type-safe data structures. - Analyze the time and space complexity of different data structures using Big O notation. The course begins with essential definitions and memory basics before walking you through structured written explanations and code examples for each structure. You will finish with practical, written exercises designed to reinforce your understanding of algorithm design. This course is designed for beginner Java programmers who want to learn computer science fundamentals without any complex setup or prior algorithm experience. Start reading today to elevate your programming logic and software design skills.
