14 Excellent Free Books to Learn Java
Last Updated on September 19, 2024
Java is a general-purpose, concurrent, class-based, object-oriented, high-level programming language and computing platform first released by Sun Microsystems in 1995. It is related in some ways to C and C++, in particular with regard to its syntax, and borrows a few ideas from other languages. Java applications are compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture.
Java is designed to be simple enough that many programmers can quickly become proficient in the language. It’s one of the most popular programming languages especially for client-server web applications.
Some popularity indexes show that Java holds the top spot with C. The respected TIOBE Index shows Java remains the most popular programming language.
We recommend the following Java books. All of them are free to download.
1. Introduction to Programming Using Java, Eighth Edition by David J. Eck
[画像:Introduction To Programming Using Java]The Eighth Edition of Introduction to Programming Using Java is a free, on-line textbook on introductory programming, which uses Java as the language of instruction.
This book is directed mainly towards beginning programmers, although it might also be useful for experienced programmers who want to learn something about Java.
The book isn’t designed to provide complete coverage of the Java language, but it’s an excellent introductory text.
2. Think Java – How to Think Like a Computer Scientist by Allen B. Downey, Chris Mayfield
[画像:Think Java]Think Java is an excellent introduction to Java programming for beginners.
Chapters cover:
- Variables and types
- Input and output
- Void methods
- Conditionals and logic – includes conditional execution, alternative execution, chained and nested conditionals, the return statement, type conversion, recursion, and stack diagrams for recursive methods
- Value methods including composition, overloading Boolean expressions and methods, and logical operators
- Iteration and loops examines the while statement, tables, two-dimensional tables, and encapsulation
- Strings and things – characters, length, traversal, run-time errors, reading documentation, the indexOf method, looping and counting and more
- Mutable objects – use two objects from Java libraries, Point and Rectangle
- Create your own objects
- Arrays – a set of values where each value is identified by an index
- Arrays of Objects – defines a Card class and write methods that work with Cards and arrays of Cards
- Objects of Arrays – creates a Deck class and write methods that operate on Decks
- Object-oriented programming – presents object-oriented programming (OOP) and transforms the Card and Deck classes into a more OOP style
- GridWorld: Part 3
- Appendices: Graphics, Input and Output in Java, Program development, and Debugging

3. Open Data Structures by Pat Morin
[画像:Open Data Structures]Open Data Structures covers the implementation and analysis of data structures for sequences (lists), queues, priority queues, unordered dictionaries, ordered dictionaries, and graphs.
The book and is released under a Creative Commons Attribution License. Read the book for free – released in HTML, PDF, and the book’s LaTeX, Java/C++/Python sources can be downloaded from GitHub. There is also a paperback version to buy. The book has been translated into Slovenian and Turkish.
Chapters cover:
- Array-Based Lists – implementations of the List and Queue interfaces where the underlying data is stored in an array, called the backing array
- Linked Lists – studies implementations of the List interface, using pointer-based data structures instead of arrays
- Skiplists – a data structure which has a variety of uses
- Hash Tables – focuses on two of the most common implementations of hash tables: hashing with chaining and linear probing
- Binary Trees – introduces one of the most fundamental structures in computer science
- Random Binary Search Trees
- Scapegoat Trees – a binary search tree data structure
- Red-Black Trees – a version of binary search trees with logarithmic height
- Heaps – discusses two implementations of the priority Queue data structure
- Sorting Algorithms – discusses algorithms for sorting a set of n items
- Graphs – study two representations of graphs and basic algorithms that use these representations
- Data Structures for Integers
- External Memory Searching
The book is available in HTML, PDF, Java sources.
