GoodrichTo Isabel Roberto TamassiaTo Susan, Calista, and Maya Michael H. GoldwasserPreface to the Sixth EditionData Structures and Algorithms in Javaprovides an introduction to data structuresand Algorithms , including their design, analysis, and implementation. The majorchanges in this sixth edition include the following: We redesigned the entire code base to increase clarity of presentation andconsistency in style and convention, including reliance ontype inference, asintroduced in Java 7, to reduce clutter when instantiating generic types.

7 We added 38 new figures, and redesigned 144 existing figures. We revised and expanded exercises, bringing the grand total to 794 exercises!We continue our approach of dividing them into reinforcement, creativity,and project exercises. However, we have chosen not to reset the number-ing scheme with each new category, thereby avoiding possible ambiguitybetween exercises such as , , The introductory chapters contain additional examples of classes and inheri-tance, increased discussion of Java s generics framework, and expanded cov-erage of cloning and equivalence testing in the context of data Structures .

8 A new chapter, dedicated to the topic of recursion, provides comprehensivecoverage of material that was previously divided within Chapters 3, 4, and9 of the fifth edition, while newly introducing the use of recursion whenprocessing file systems. We provide a new empirical study of the efficiency of Java sStringBuilderclass relative to the repeated concatenation of strings, and then discuss thetheoretical underpinnings of its amortized performance. We provide increased discussion of iterators, contrasting between so-calledlazy iteratorsandsnapshot iterators, with examples of both styles of imple-mentation for several data Structures .

9 We have increased the use of abstract base classes to reduce redundancywhen providing multiple implementations of a common interface, and theuse of nested classes to provide greater encapsulation for our data Structures . We have included complete Java implementations for many data structuresand Algorithms that were only described with pseudocode in earlier new implementations include both array-based and linked-list-basedqueue implementations, a heap-basedadaptablepriority queue, a bottom-upheap construction, hash tables with either separate chaining or linear probing,splay trees, dynamic programming for the least-common subsequence prob-lem, a union-find data structure with path compression, breadth-first searchof a graph.

10 The Floyd-Warshall algorithm for computing a graph s transitiveclosure, topological sorting of a DAG, and both the Prim-Jarn k and Kruskalalgorithms for computing a minimum spanning assume that the reader is at least vaguely familiar with a high-level program-ming language, such as C, C++, Python, or Java, and that he or she understands themain constructs from such a high-level language, including: Variables and expressions Methods (also known as functions or procedures) Decision Structures (such as if-statements and switch-statements) Iteration Structures (for-loops and while-loops)For readers who are familiar with these concepts, but not with how they are ex-pressed in Java, we provide a primer on the Java language in Chapter 1.

Data Structures and Algorithms in Java

The design and analysis of efficient data structures has long been recognized as a key component of the Computer Science curriculum. Goodrich, Tomassia and Goldwasser’s approach to this classic topic is based on the object-oriented paradigm as the framework of choice for the design of data structures. For each ADT presented in the text, the authors provide an associated Java interface. Concrete data structures realizing the ADTs are provided as Java classes implementing the interfaces. The Java code implementing fundamental data structures in this book is organized in a single Java package, net.datastructures. This package forms a coherent library of data structures and algorithms in Java specifically designed for educational purposes in a way that is complimentary with the Java Collections Framework.

Fundamental data structures in a consistent object-oriented frameworkNow revised to reflect the innovations of Java 5.0, Goodrich and Tamassia’s Fourth Edition of Data Structures and Algorithms in Java continues to offer accessible coverage of fundamental data structures, using a consistent object-oriented framework. The authors provide intuition, description, and analysis of fundamental data structures and algorithms. Numerous illustrations, web-based animations, and simplified mathematical analyses justify important analytical concepts.Key Features of the Fourth Edition:* Updates to Java 5.0 include new sections on generics and other Java 5.0 feature.

A Practical Guide to Data Structures and Algorithms

Using Java

Although traditional texts present isolated algorithms and data structures, they do not provide a unifying structure and offer little guidance on how to appropriately select among them. Furthermore, these texts furnish little, if any, source code and leave many of the more difficult aspects of the implementation as exercises. A fresh alternative to conventional data structures and algorithms books, A Practical Guide to Data Structures and Algorithms using Java presents comprehensive coverage of fundamental data structures and algorithms in a unifying framework with full implementation details. Recognizing that software development is a top-down process, this applications-centered book provides careful guidance to students and practitioners. Complete .
