Data Structures and the Java Collections Framework, 3rd Edition

Data Structures and the Java Collections Framework, 3rd Edition

William J. Collins

Jan 2011

768 pages



Offering students and instructors a practical approach to program design, testing and implementation, this text utilizes the Java Collections Framework, part of the java.util package, as a platform to develop higher-level applications.

This updated third edition features an increased emphasis on testing. The unit testing features of JUnit4 ? with the test-first model ? are introduced early, in chapter 2, and integrated in applications throughout the remaining chapters. In addition, there is ample opportunity for hands-on practice, including 23 lab experiments, hundreds of programming exercises and more than 30 programming projects.

  • There is an increased emphasis on testing. In particular, the unit-testing features of JUnit 4 are introduced in Chapter 2 and integrated in applications throughout the remaining chapters.
  • The Scanner class has replaced the BufferedReader and StringTokenizer classes. The Scanner class s versatility supports pattern matching as well as keyboard input and file input.
  • Utilizes the Java Collections Framework, part of the java.util package, as a platform to develop higher-level applications.
  • Where necessary, the author includes approaches that differ from those in the Framework including a separate section on open addressing, and a discussion of the trade-offs of one design over the other.
  • Students have the opportunity to develop their own data structures via programming projects in which data structures are either created “from the ground up” or extended from examples in the chapters.
  • 23 Web Labs promote active learning and provide reinforcement of the text material. The labs encourage the use the scientific method, and each lab is set up as an experiment.
  • A “theme” project is introduced in chapter 2 and continues through six of the remaining chapters. This project clearly illustrates the practical value of understanding data structures.
