Question about the task

Restaurant (part 15)

Java Multithreading, Level 9, Lesson 15

Resolved

I created the ManagerTablet object in Restaurant class, and called the methods. Can't get what the problem could be.

Let's think about what needs to be done so that the manager can view the following:
1) advertising revenues, grouped by day;
2) cook utilization (time spent working), grouped by day;
3) list of active videos and the number of remaining impressions for each;
4) list of inactive videos (with zero remaining impressions).

For each item, we'll add a corresponding method to StatisticsManager.
The manager will call the method, and StatisticsManager will perform the various calculations.
But the manager has to call these methods from somewhere. We'll give him or her a tablet, but with different software.
To do this, we'll create a ManagerTablet class that has a nice interface and the ability to access statistics.

1. Create the ManagerTablet class at the root of the project.

2. In the ManagerTablet class, create four void methods:
printAdRevenue(), printCookUtilization(), printActiveVideoSet(), printArchivedVideoSet()
They correspond to the four items listed above.

3. To make it possible to check the result, in the main method, create a manager's tablet and display statistics using the methods listed above.

We're going to need some more methods.

4. In EventDataRow, create the following methods:
Date getDate(), which returns the row's creation date int getTime(), which returns the duration

5. In StatisticsManager, create a void register(Cook cook) method, which will register the cook.
In the StatisticsManager class, create a Set cooks field and add the cook.

6. Implement the necessary getters in the OrderReadyEventDataRow, NoVideosAvailableEventDataRow, and VideosSelectedEventDataRow classes.

Requirements:

The ManagerTablet class must have the methods listed in the task conditions.
The Restaurant class's main method must create a new ManagerTablet and call methods to display statistics.
The EventDataRow interface must declare getDate and getTime methods.
The StatisticsManager class must implement a register method with one Cook parameter, that registers the cook in the cooks field (set of all cooks).

Try to create one order and not 4.
