Object-Oriented Design and Patterns 2e, makes it easy to add object-oriented design early in the CS curriculum. Suitable for students who have had one or two semesters of programming (Java or C++), the book can be used in a second or third course (before or after data structures), or as a companion text in a later course in software design or software engineering. Cay Horstmann brings his hallmark approach to the book-sound pedagogy, carefully developed exercises and examples, and emphasis on problem solving-and brings design principles and patterns to life with examples from the Java 5.0 library and user-interface programming. Students will expand their understanding of the Java language as they learn to recognize and use object-oriented design principles.
