Constructor must have the same as the class name,
whereas we can give any name to the method.
Constructor doesnt have any return type not even void,
whereas method must have valid return type or void if
nothing is return.
Constructor will implicitely invoke at the time of
object creation, whereas method must invoke explicitely
with the object.
