Algorithms in Java

The book "Algorithms in Java" is a practical guide to designing, analyzing, and implementing algorithms in the Java language. It is intended for students, novice developers, and experienced programmers who wish to deepen their knowledge of algorithmization and data structures. The reader will learn how to efficiently solve problems of sorting, searching, working with graphs, dynamic programming, and many others, using the capabilities of the Java Collections Framework and modern approaches to code optimization.

The book consists of 12 chapters. The first chapters are devoted to the basics of complexity analysis (Big O notation) and basic structures: arrays, linked lists, stacks, and queues. Next, recursion, sorting algorithms (quick sort, merge sort, heap sort) and search algorithms (binary search, interpolation search) are discussed. Separate chapters cover hash tables, trees (BST, AVL, red-black trees), graphs (BFS, DFS, Dijkstra's algorithm, A*), as well as greedy algorithms and dynamic programming problems. The book concludes with a section on parallel algorithms in Java (Stream API, ForkJoinPool) and test tasks for self-assessment.

Why should you read this book? Firstly, it combines theory with real code examples in Java that can be run immediately. Secondly, the author focuses on performance and typical implementation errors. Thirdly, the book will prepare you for technical interviews at IT companies, where algorithmic problems are a mandatory part. Finally, the 2024 edition takes into account the latest Java updates (versions 17 and 21), including new methods in collections and improvements in memory management.

Who is this book for? For Java developers of any level who want to systematize their knowledge of algorithms, as well as for students of technical specialties. If you already know how to write simple programs in Java but want to move to the next level, this book will be your reliable assistant.
