CS *254: Concurrent Object-Oriented Programming in Java and Android CS *254: Concurrent Object-Oriented Programming in Java and Android Douglas C. Schmidt d.schmidt@vanderbilt.edu Department of Electrical Engineering and Computer Science School of Engineering Vanderbilt University Times and Location Classroom -- Engineering Science Building (ESB) room 48, Monday and Wednesday from 8:45-10am Final exam time is Friday, April 24th at 9am in the class room. Philosophy Developing high quality concurrent object-oriented software in Java for Android mobile devices is hard; developing high quality reusable concurrent object-orietned software is even harder. The principles, methods, and skills required to develop reusable software cannot be learned by generalities. Instead, developers must learn through experience how reusable concurrent components and frameworks can be designed, implemented, optimized, validated, maintained, and enhanced by applying good object-oriented development practices and patterns. Prerequisites Proficiency in Java, i.e., as covered in CS 101 Proficiency in software patterns, i.e., as covered in CS 251 Knowledge of email, the Web, and online discussion forums Awareness of--and adherence to--the Vanderbilt University Honor Code that governs all work in this course (e.g. tests, quizzes, homework assignments, etc.), which must be done individually and in a "closed-book" manner (i.e., no outside help, no Internet, etc.) Course Logistics Office Hours and Locations Assignment Deadlines Course FAQ Programming Assignment Process and Submission Guidelines Course Overview Patterns of Learning Synopsis of Course Contents Summary of Course Work Textbook and Recommended Reading Course Videos and Slides By Week All the lecture videos for this course will be available on my YouTube playlist as they are created.
