Q9. Consider the following Java class.
public class Clock {
private Integer startTime;
private Integer numHours;
public Clock( Integer start, Integer hrs ) {
startTime = start;
numHours = hrs;
}
}
Modify this class and introduce any other code required, but without using any
standard Java Collection Framework classes or interfaces (e.g.,
List
), so that you can
iterate over an instance of
Clock
using a for-­‐each loop. For example, the following
code should print the numbers 2, 3, 4, and 5. You do not have to consider the case
where the hours go past 23. Assume the input you’re given will produce output
within the same day (i.e., values between 0-­‐23 only).
for (Integer i: new Clock(2,4)) {
System.out.println(i);
}
Q10. Suppose you are designing an Android app that will allow the user to perform task
management. The user can add tasks to the system and can group tasks together
into projects. Projects can be added as sub-­‐projects of other projects, nested
arbitrarily deep. Each task has an estimated time for completion that is specified
when the task is constructed. You want to be able to treat individual tasks and
projects in the same way. In particular, you want to be able to get the time needed
to complete a task or a project. The time taken to complete a project is the total
time needed to complete all the tasks in the project or in sub-­‐projects of that project.
a) Consider the partially completed code in the
lectures/TaskManager
project.
Draw a UML diagram that includes all the classes in the
ca.ubc.cpsc210.taskmanager.model
package and that shows how you will
apply the composite pattern to the design of this system.
b) Write the complete implementation of the
Task
and
Project
classes. Note that all
the tests provided in
ca.ubc.cpsc210.taskmanager.tests.TestProject
should pass. Space is also provided on the following page for your answer to this
question.
