System

> pre-defined class in java.lang package
out
--------
out- it is a static variable inside System class of type PrintStream(class reference variable)
(ie) static PrintStream out;
and PrintStream is a predefined class in java.io package.
since its static thats why we are calling

so System.out means we are getting the reference to the object of type PrintStream

println is the method in PrintStream class for Standard output stream.
so to access println method , i need PrintStream object which we are getting through System.out.
so finally
its System.out.println---- to produce standard output Stream
println-method name
