System.out.println()

System - class
out - object
println() - function

Answer 2

Are you referring to this:
System.out.println(); ??

If so, that will move the console to the next line.
So,
System.out.println();
System.out.println("Hi!");

'Hi!' will be placed on the 2nd line in the console.

Answer 3

yes I am referring that
