What is it?

By saving it in a variable, you have access to the console throughout your code and only create one instance of the object (which saves memory).
The console is used to get information from the user and display information to the user. For example, you could make a simple calculator program that asks the user for a list of numbers and then display their average. Console is primarily used in applications without a Graphical user interface.
Console come from an external package provided by Java, but is not included by default. In order to get access to the Console you have to use
import java.io.Console;
This tells java you would like to use the console.
Let me know if there is anything else I can clarify

Courses Plus Student 7,593 PointsIm not totally sure what your looking for; however, It looks like you forgot your parenthesis at the end of System.console. Try this:
Console console = System.console();
