Last condition no verifying

Question about the task

MVC (part 4)

Java Multithreading, Level 4, Lesson 14

Resolved

Hi, does someone please know why the last condition isn't verifying for me? Thanks

It's time to replace our fake Model with a real one that receives data from the DataSource.
I've added a service for working with users to the model.service package.
You'll also find a Util utility class in the root of this task.

1. Create a MainModel by analogy with FakeModel.

2. Because the Model accesses services, create and initialize a UserService userService field in MainModel.

3. Implement the loadUsers method:
3.1. Get all users between levels 1 and 100. (Use the getUsersBetweenLevels(1, 100) method.)
3.2. Put all of the users into dataModel.

4. Update Solution.main: replace FakeModel with MainModel.
An advantage of MVC is that it's easy to replace any part of the pattern at any time.

Requirements:

A MainModel class that implements the Model interface must be created inside the model package.
A private DataModel dataModel field must be created and initialized in the MainModel class.
A private UserService userService field must be created and initialized in the MainModel class.
You must implement the getDataModel method in the MainModel class.
The MainModel class's loadUsers method must be implemented according to the task conditions.
You must create a MainModel object instead of a FakeModel object in the Solution class's main method.

Where did your FakeModel class go?

I deleted it, because I though there was no point to it anymore. I returned it back and it passed now. Thanks
