Sedgwick and Wayne’s book Algorithms in Java is a classic reference guide that contains the requisite body of knowledge for the programmer in the field of algorithms accumulated over the past few decades
The book covers a wide range of topics: a comprehensive explanation of data structures and algorithms for sorting, searching, graphing, and string processing, including fifty algorithms (code on site) that every programmer should know. Describes new implementations of algorithms in Java, written in a clear, modular style in which all the code is accessible to the reader and fully ready to use. The book explores algorithms in Java in the context of critical scientific, engineering, and commercial applications. Clients and algorithms are expressed using real code, not pseudocode as in many other books.
What sets this book apart from many others is its clear and concise text, detailed examples with illustrations, carefully chosen code, historical and scientific context, and exercises for self-study at all levels. The book presents accurate performance considerations supported by appropriate mathematical models and empirical studies that support the validity of these models.
