System.out.println();
System is the Class in which out is static object of
class PrintStream which refers t othe standard output ie
console output,
and PrintStream class contains the method println()
which will be accessed using PrintStream object out.
Since out is static so it can be only accessed using
class name in which it contains.
so System.out.println(); simply invokes println()
method to output specified data to standard output console.
