Hi Ketul,
In a bean, the variables like setters and getters must follow a strict name
convention. In the class Person, if you have a variable "name", then you must
have a setter setName() and a getter getName(). In the class Name, you have
variables firstName and lastName, then you must have setters setFirstName() and
setLastName(). Note that the first character after "set" must be in upper case
(i.e. "F" and "L"). Similarly, you must also have getters like getFirstName()
and getLastName().
I hope this helps.
Regards,
Trung.
