Description: This course considers the design and implementation of network-based applications. It focuses on object-oriented design and programming techniques at the application layer. It considers text transport, data transport, object transport, function/procedure call transport, and class transport.

In lectures we will consider several example applications, but will focus on the design and implement a "WWW Server" of increasing sophistication. This "WWW Server" will be used to both motivate and explore the topics we discuss. You will then use and expand on and use this "WWW Server", and associated "WWW Clients", in a sequence of programming assignments.

Textbook: Readings for this course are primarily from the following books and The Java Tutorials.

Outline: This course is organized as follows (though specific topics and dates may change).

Lectures in this course will be delivered on-line during scheduled meeting times. Students may participate in lectures synchronously, or watch a recording asynchronously (at any time after it has been delivered).

Some course meeting times will be devoted to face-to-face discussion/question-and-answer sessions. For these sessions, students have been divided into two groups/cohorts, purple and gold. Students may attend these sessions only with their assigned cohort. When the other cohort is meeting, you may use the time as you see fit.

Exams will be delivered on-line during scheduled exam times.

Grading: Final grades will be based on your performance on: 3 in-class exams (25% each) , 1 final project (10% total) and several programming assignments (15% total).

Programming Assignments: 10 programming assignments will be assigned during the semester. Note that their due dates are subject to change.

Make sure you read and understand all of the policies related to programming assignments. Programming assignments may not be submitted after the due date/time (in other words, you will receive a grade of 0 on any programming assignment that is not submitted on time).

Final Project: Each student must complete a (team) project. All project proposals are due on 11/16 11:00PM. All project materials are due on the day of the presentation . A Team Evaluation Form (which will be made available to you just before the project ends) must be completed and submitted by each member of the Team individually by 12/16. Make sure you read and understand all of the policies related to projects.

Office Hours: You may meet (either face-to-face or virtually, depending on the situation and schedule) with Prof. Bernstein during his scheduled office hours or you may schedule an appointment with him.
