'system' is a public class which is final which can never
be extended..It does not extends object.
'out' is the static variable of the class PrintStream desclared in system class.
'println()' is the method of printStream class..
since 'out' is a static variable it can be called by using
the class name'system'
so 'Sstem.out.println()'
