Java.util.Map issue

In principle the thing i set out to do (to create a username and password database) works but I want to organize my code more into different classes. While doing this I have an issue accessing a Map in another class and i can't seem to find the reason why ...

Console output

users size: 0

Enter your username: Test Enter your password: 123

users size: 1 users size: 0 (<---- these are to test if the Loader class is picking up the value of the key i entered )

Welcome to my very first Prototype BattleShip game 'test' :) !!

Enjoy!!

Try 1, Enter an X and a Y coordinate (like this) <12>(with numbers from 0-4):

Code:

Prompter Class:

Loader Class:

The images should be readable if you zoom in.

Ok, let's do it.

Let me understand the problem, i run the app and i don't see any problem initialize.

What map do you want access and from where the access will be make?

I want to access the map users in the prompter class through the loader class.

I added a bit of test code to see if the loader class was picking it up , but it keeps displaying a size of 0 and it is not saving the value in the userMap txt.
