A java logic problem.
So in this part of the video we need to access a method from the Resources class.
So I thought you would have to initialize it first like this
Resources resources = new Resources;
and afterwards you have access to all the methods inside that class.
Instead in the video he just created and variable and had access to the variable directly like this
Resources resources = getResources();
Am I missing something?

The resources you want to access already exist, so you don't want to create a new (empty) object here. The "getResources" method is inherited from the context class, and returns a reference to that existing resource object.

response to: Why can't we do - String key = getResources().getString(R.string.key_name); - directly without setting the method to a variable?
You can do that.
The difference in required computing power is quite small
If you are using them a lot, it saves a bit of typing
