Algorithms and Data Structures in Java: From Basics to Advanced Techniques

The book "Algorithms and Data Structures in Java" is a practical guide that will help you master fundamental computer science concepts and learn to apply them in real-world projects. Whether you are preparing for a technical interview or want to write more efficient code, this book will be your reliable companion.

What this book is about

The book covers a full range of topics — from basic data structures (arrays, lists, stacks, queues) to complex algorithms (sorting, searching, graphs, dynamic programming). Each topic is accompanied by detailed examples in Java, visualizations, and time complexity analysis. Special attention is given to practical aspects: how to choose the right data structure for a specific task and how to optimize an algorithm.

Who this book is for

• Beginning Java developers — those who want to build a solid foundation for a career in IT.
• Technical students — for in-depth study of algorithms as part of their curriculum.
• Experienced programmers — to systematize knowledge and prepare for interviews at top companies.
• Self-taught learners — anyone who prefers a structured approach with plenty of examples.

What you will learn

• How arrays, linked lists, stacks, queues, and trees (including binary search trees and red-black trees) work.
• Sorting algorithms: from bubble sort to quicksort and heapsort — their implementation and performance comparison.
• Working with graphs: traversals (BFS, DFS), shortest path search, topological sorting.
• Hash tables and their application in real-world projects.
• Fundamentals of dynamic programming and greedy algorithms.
• How to analyze algorithm complexity using Big O notation.

Book features

• Over 100 ready-to-use code examples with comments.
• Step-by-step explanations of complex concepts.
• Exercises for independent practice with answers.
• Tips for preparing for interviews at IT companies.
