Preface

Java has been one of the most popular programming languages for enterprise systems for decades now. One of the reasons for the popularity of Java is its platform independence, which lets one write and compile code on any system and run it on any other system, irrespective of the hardware and the operating system. Another reason for Java's popularity is that the language is standardized by a community of industry players. The latter enables Java to stay updated with the most recent programming ideas without being overloaded with too many useless features.

Given the popularity of Java, there are plenty of developers actively involved in Java development. When it comes to learning algorithms, it is best to use the language that one is most comfortable with. This means that it makes a lot of sense to write an algorithm book, with the implementations written in Java. This book covers the most commonly used data structures and algorithms. It is meant for people who already know Java but are not familiar with algorithms. The book should serve as the first stepping stone towards learning the subject.
