Draw one sequence diagram that shows the method calls of the doAdd and add methods. Activation boxes are required. A complete solution has 6 objects. It's important to note that this is to be done with JAVA in mind as the programming language; hence why the correct answer will HAVE 6 objects.

Consider the following 2 (incomplete) classes:

public class Console { private Scanner in; private PrintStream out; private ApptBook book; private void doAdd() { 

 out.print("Enter the appointment (descr start end):"); Appt a = new Appt(in.nextLine()); book.add(a); out.println("Added appointment " + a + " "); 

} }

public class ApptBook { private ArrayList apptList = new ArrayList(); public void add(Appt a) { 

 apptList.add(a); } 

}
