Question about the task

Under discussion

I don't know how to put the separator in a new line in the refresh(dataModel) method in the editUserView. And I have problems in the refresh UserView method.

The functionality for displaying deleted users exists, but we don't have any deleted users. Let's fix that.
Let's make a new view that will be responsible for editing a specific user.
UsersView displays a list of users.
EditUserView will display data about editing a specific user.
For this, we first need the selected user.
As with any data, we'll put it in DataModel.

1. In DataModel, create a User activeUser field, along with a corresponding getter and setter (Alt+Insert -> Getter and Setter).

2. Create EditUserView by analogy with UsersView.
Here's the logic for the refresh method:
2.1. Display "User to be edited:".
2.2. On a new line, display a tab and then the active user.
2.3. On a new line, display the following separator: "===================================================".

3. Create a EditUserView editUserView field and corresponding setter in the controller.

When our data is displayed, it's not entirely clear whether we are displaying the list of users or the list of deleted users.
Let's make the View display this information. All of the data to be displayed is stored in the Model.

Therefore,
4. In DataModel, create a boolean displayDeletedUserList field, along with a corresponding getter and setter.

5. Change the UsersView class's refresh method so that it displays "All users:" or "All deleted users:"
depending on the type of users in the list.
Add the displayDeletedUserList change to the required methods of the model.

Requirements:

A private User activeUser field, and a corresponding getter and setter, must be created in the DataModel class.
The EditUserView class must be created by analogy with the UsersView class: it must support the View interface and have a private Controller controller field and corresponding setter.
The EditUserView class's refresh method must be implemented according to the task conditions.
A private EditUserView editUserView field and corresponding setter must be created in the Controller class.
A private boolean displayDeletedUserList field and corresponding getter and setter must be created in the DataModel class.
The UsersView class's refresh method must be modified according to the task conditions.
You need to add a call to the setDisplayDeletedUserList(boolean) method using the correct flag in some of the MainModel class's methods.

EditUserView

@Override
    public void refresh(DataModel dataModel) {
        System.out.println("User to be edited:");
        System.out.println("\t" + dataModel.getActiveUser());
        System.out.println("===================================================");
    }

UsersView

@Override
    public void refresh(DataModel dataModel) {
        if (dataModel.isDisplayDeletedUserList()) {
            System.out.println("All deleted users:");
        } else {
            System.out.println( "All users:");

        }

        for (User user : dataModel.getUsers()) {
            System.out.println("\t" + user);
        }
        System.out.println("===================================================");

    }
