A constructor in java has the same name as that of the
class. Whenever the statement such as classname objectname
is encountered, it calls the constructor to initialise the
values for the object. It doesnot return anything and as
soon as the object is created constructor would be called.

ex. : if there is a class called A

A a = new A();
here A a statement would call the constructor immediately
to initialise the values for a object.
