443 PointsObject Reference Variables
I always have a problem understanding this aspect of object reference variables. Can someone please assist.
Console console = System.console();
in a normal object reference it would create a new object "Console" and assign that to the name of the reference variable (console). But this one i'm not sure about. Console is being accessed/initiated and it is referencing System.console? is System.console apart of console? please assist.

In this line, the first word, "Console" is a class. The second word "console" is an object of type "Console" class. This "console" object is used to take input from the console (i.e., the terminal where you compile and/or run your java program). You are doing this by assigning "System.console()" method which reads the input from console.
