System : The System is a class and cannot be instantiated.

out : Its a static field with type PrintStream of System
class and object of PrintStream class.

println : Its a method of PrintStream class.

As "println()" is a method of PrintStream class and "out"
is an object of PrintStream class, object can call its
public method "println()"
out.println();

Since "out" is static , it so that it is called using class
name "System"
System.out.println()
