Programming Ideas
This book is 100% completeLast updated on 2026-07-20
Programming Ideas closes the gap between introductory programming books and computer science textbooks. It teaches you how to write programs that solve a wide range of practical problems, from drawing fractals to compressing files and computing Pi, and it carefully explains both the required programming techniques and the resulting programs.

About the Book
Would you like to take your programming skills to the next level? Are you looking for ideas on what to program next? Have you outgrown the simple toy programs discussed in most programming books? In this case, Programming Ideas might be the book for you.
Programming Ideas is based on the notion that reading and writing real programs is the only way to master programming. Therefore, instead of teaching you how recursion works in theory, the book demonstrates a wide range of practical applications, from drawing fractals and geometric curves to multiplying arbitrarily large integers. The same approach is used to illustrate many other concepts such as backtracking, graph algorithms, functional programming, encoding data using bits, hashing, and computer arithmetic. All topics are illustrated using complete, working Java programs.
The book was designed with self-learners in mind: every chapter includes a wide range of exercises and programming projects, usually with complete solutions.
The online version of the book is available for free at programmingideas.net/book.

About the Author
Daniel Heck
I'm a programmer and freelance writer based in northern Germany. Previously, I worked as a research assistant at the University of Konstanz and as a software engineer at Nik Software and Google. Programming Ideas is my attempt to capture what I love about programming. It covers many of the topics I was interested in when I learned programming back in high school—in many ways, it's the programming book I was missing back then.
