System is class in java.lang package

out is a static member of type PrinStream class(java.io)
declared in the System class.static members of a class can
be accessed directly by classname that's why System.out.

println is a method in PrintStream class.out is of type
PrintStream that's why you access println w.r.t out.

why this big statement? because here no need to import any
package, like you include a header file in c or
c++.java.lang is the default package.
