   *Material and going beyond*
   
  
positive.code: 
  === Book exercices
  * Create a personal repository named `Java-L3-Eck-Ex`. You deposit the book exercices (EE) there. All related classes must be prefixed with `EExx`, for example `EE34MyClass`.
  * All mandatory exercices must be in the appropriate repository, merged in the branch `master`, 3 days before the lecture, 23:59 + 1min (e.g., lecture Saturday 23rd means a deadline on the end of Wednesday 20th).
  * For the book exercices, you receive either 1 (exercice is done, even imperfectly, committed under your name) or 0 (exercice not done). This counts for 10% of the CC grade. (Once graded, you can remove the book exercices in your repository, or leave them there.)
  
  === Project
  * Create a group repository (once for the group).
  
negative.code: * Read half of the Workbench User Guide, Basic Tutorial, see https://github.com/oliviercailloux/java-course/blob/master/Tools.adoc#eclipse[Eclipse] doc [I]
  * http://math.hws.edu/eck/cs124/javanotes7/c1/quiz.html[EQ1.3] to 1.9
  * http://math.hws.edu/eck/cs124/javanotes7/c2/quiz.html[EQ2.1] to 2.4; 2.6 to 2.9; 2.11
  * Commit the mandatory exercices above: see https://github.com/oliviercailloux/java-course/blob/master/Divers/L3a.adoc#book-exercices[Instructions]
  ** Do /not/ send me an e-mail to give me your username, or your repository URL. I’ll find it out.
  ** You are not obliged to use the command `git` to send your files on GitHub for now, you may do it “manually” with your web browser. Here is how. (Or watch this http://www.youtube.com/watch?v=pgzOiH1kmnI&t=1m20s[video], from 1min 20s to 4min.)
  *. When creating your repository, check the box “Initialize this repository with a README” (the goal is simply to make your repository non-empty)
  *. You can use the `Upload files` button or directly drag and drop your Java files on your resulting repository
  *. Keep the default option: “Commit directly to the `master` branch”, click `Commit changes`.
  * Indicate your GitHub username on https://mycourse.dauphine.fr/webapps/blackboard/execute/launcher?type=Course&id=_38274_1[MyCourse].
