Programming Language

The coding language used for all of the implementations is Java. The programs use a wide range of standard Java idioms, and the text includes concise descriptions of each construct.

Mike Schidlowsky and I developed a style of Java coding based on abstract data types that we feel is an effective way to present the algorithms and data structures as real programs. We have striven for elegant, compact, efficient, and portable implementations. The style is consistent whenever possible, so programs that are similar look similar.

For many of the algorithms in this tutorial, the similarities hold regardless of the language: Quicksort is quicksort (to pick one prominent example), whether expressed in Ada, Algol-60, Basic, C, C++, Fortran, Java, Mesa, Modula-3, Pascal, PostScript, Smalltalk, or countless other coding languages and environments where it has proved to be an effective sorting method. On the one hand, our code is informed by experience with implementing algorithms in these and numerous other languages (C and C++ versions of this tutorial are also available); on the other hand, some of the properties of some of these languages are informed by their designers' experience with some of the algorithms and data structures that we consider in this tutorial.

constitutes a detailed example of this approach to developing efficient Java implementations of our algorithms, and describes our approach to analyzing them. Chapters 3 and 4 are devoted to describing and justifying the basic mechanisms that we use for data type and ADT implementations. These four chapters set the stage for the rest of the tutorial.
