Prof. Dr. M. Mühlhäuser Telekooperation © : Organization 3 topics, each lecture + assignment Lecture covers theory, assignment implements it Assignments have milestones –For measuring progress (for you and us ) –~3 milestones / assignment –First assignment 2 week long, assignment 2 is 4 weeks long, and assignment 3 is ~1.5 months long Teams of 2-3 students, one grade for whole team Overall grade as average of assignment grades –Weights: 1/4, 1/4, 1/2 Teams discovered cheating will get a grade of 5,0 for the whole assignment

Prof. Dr. M. Mühlhäuser Telekooperation © : What You Need to Do (1) In each assignment, return the following: 1.Compiled JAR-File Executable!!! Including Java source code The code should follow the coding guidelines given on the next pages Code not following the guidelines may be graded inferior compared with functionally equivalent code that does follow them 2.Short written report What you have done, what is missing, how you implemented it Describe design choices, why you did them, etc. UML diagram is ok, if you know UML

Prof. Dr. M. Mühlhäuser Telekooperation © : What You Need to Do (2) 3.Test cases used Test cases may be defined informally in the written report or formally with JUnit tests 4.The names and Martikel numbers of all people in the group must be present in the written report and in the Return as a zip-file by to

Prof. Dr. M. Mühlhäuser Telekooperation © : Coding Guidelines (1) Note: The guidelines are not designed to be in your way – you might already program according to them just because it is the Right Thing to do anyway The code should compile (with JDK up to 1.6) if you are using 1.5 extensions (e.g., enums, generics), there is no need to mention that explicitly Your code should be readable – indent blocks, use capitalization conventions The program’s design should follow OO best practices Examples: information hiding, typing with interfaces, modularization, avoiding static for everything but main() and constants, …

Prof. Dr. M. Mühlhäuser Telekooperation © : Coding Guidelines (2) The code should contain comments Minimum: JavaDoc for each public method and each public class with one sentence Use self explaining names for variables, methods and classes self explaining != long for(int i = 0; i < size; i++) is self explaining public Node _n is not self explaining External libraries are permitted only for things that are not part of the assignment Example: libraries for logging or UI generation are okay, libraries for socket handling are not If you are using external libraries, you must turn them in with your assignment
