          Figure 1: Class diagram of Simple Watch

          Figure 1: Class Diagram of Simple Watch ((umltd4.pdf (free.fr))
          .

          From the class diagram of the Figure 1:

          1) Provide a sequence diagram to model a scenario where a user would like to set the time (specifically the minutes) on their watch.

          2) Provide a communication diagram from the resulting sequence diagram.

          3) Develop the corresponding State Chart Diagram.

          Note: By pressing button 1 twice, you access the minute setting (hour flashes then minute flashes). Then with button 2 (without releasing the button) it increments the minutes; the LCD display is refreshed. By pressing button 1 again the time is saved and the display stops flashing.

          Exercise 2: Chocolate mousse (UML2 by practice, P. Roques)

          Here is the recipe for making a good chocolate mousse:

          • Start by breaking the chocolate into pieces, then melt it.

          • At the same time, break the eggs, separating the whites from the yolks.

          • When the chocolate is melted, add the egg yolks.

          • Beat the egg whites until they are very stiff.

          • Gently incorporate them into the chocolate mixture without breaking them.

          • Pour into individual ramekins.

          • Chill for at least 3 hours in the refrigerator before serving.

          Question: Establish the activity diagram to model the recipe.

        • Test Chapter 8 (For anonymous Access) Consultation

          Part 1: Short answer questions

          1)       What is a design pattern?

          2)       What is the advantage of using design patterns?

          3)       Give 3 categories of design patterns.

          Part 2: Exercise

          Let consider two classes: a Program1 class which simply displays a message when you call the method go() and a Client class which calls Program1.

           public class Client

          { public static void main1( ) {
          Program1 p = new Program1();
          System.out.println("Je suis le main1");
          p.go(); }
          public static void main2( ) {
          Program1 p = new Program1();
          System.out.println("Je suis le main2");
          p.go(); }
          public static void main3( ) {
          Program1 p = new Program1();
          System.out.println("Je suis le main3");
          p.go(); }   }

          public class Program1

          {   public Program1() { // constructeur vide 
          }
          public void go()
          { System.out.println("Je suis le traitement 1");  }    }

          The class diagram looks like this:

          We want to add three classes Program2, Program3 and Program4 to our system. These classes will display the same message on the screen as Program1, except that they will display their program number (2, 3 or 4). Add these classes (by duplicating and modifying the code from Program1). In the client, we want to modify the code of the main functions so that, depending on the integer parameter passed to them as an argument (1, 2, 3 or 4), they launch the processing of Program1, Program2, Program3 or Program4. We suggest you applying the design pattern factory.

          Questions:

          1)       Justify why factory pattern is the appropriate pattern in this case.

          2)       Provide the java code and the corresponding class diagram.
