Object-Oriented Data Structures Using Java, Fourth Edition

Master Data Structures the Object-Oriented Way 💻

Data structures are the backbone of efficient software, and Java remains one of the most popular languages for learning them. Object-Oriented Data Structures Using Java, Fourth Edition offers a thorough, modern treatment of the subject, written by three experienced educators: Nell Dale, Daniel T. Joyce, and Chip Weems. This edition has been substantially revised to reflect current practice, with a focus on abstract data types (ADTs), software engineering principles, and the object-oriented paradigm.

What Makes This Edition Stand Out ✨

The fourth edition introduces a simplified architecture, reducing the number of inheritance levels to make the ADT interfaces easier to understand and use. Two brand-new chapters expand the book’s scope: Chapter 5, The Collection ADT, explores data structures as repositories for storage and retrieval, while Chapter 8, The Map ADT covers associative arrays and hashing, increasingly important in modern programming. Recursion gets extra attention with new sections on recursive processing of arrays and linked lists, plus a fun section on generating fractal images. A new section on concurrency and synchronization addresses the growing importance of multi-core and multi-threaded programming.

Inside the Chapters

From the fundamentals of getting organized and efficiency analysis to advanced structures like graphs and priority queues, the book builds knowledge step by step. You will explore:

• The Stack, Queue, Collection, List, Binary Search Tree, Map, Priority Queue, and Graph ADTs
• Multiple implementations for each ADT, including array-based and reference/linked-list-based approaches
• Recursion as a problem-solving technique, with a three-question verification method
• Sorting algorithms such as quick sort, heap sort, and merge sort, compared through efficiency analysis
• Graph algorithms including depth-first search, breadth-first search, shortest paths, and connected components
• Java features like generics, interfaces, exceptions, threads, and anonymous inner classes

Learn by Doing 🧠

Each chapter is packed with opportunities to apply what you’ve learned. The authors average more than 40 exercises per chapter, ranging from short programming problems to larger projects. Sample applications bring the material to life: balanced expressions, postfix evaluation, queue simulation, card games, text analysis, big integers, and fractal generation. UML class diagrams appear throughout, helping you visualize the relationships between classes and interfaces. The appendices include a glossary, Java reserved words, operator precedence, and more.

Who This Book Is For

This text is written for students who already know the basics of Java: simple data types, control structures, classes, and common library classes. It is ideal for a second or third course in computer science, whether you are a student, a self-learner, or an instructor looking for a rigorous yet approachable data structures textbook. The clear explanations and practical focus make it a valuable reference long after the course ends.

Why It Belongs on Your Shelf 📚

With its emphasis on ADTs, problem solving, and real-world applications, Object-Oriented Data Structures Using Java, Fourth Edition gives you a solid foundation for writing efficient, maintainable software. Whether you are preparing for advanced study or sharpening your professional skills, this edition offers a complete, up-to-date guide to the structures that power modern applications.
