Thread: why i still receive these errors

this code gives me the following errors,
why?
--------------------Configuration: <Default>--------------------

thank you for your help
it works now.

and sorry for being unfamiliar with the forum rules

1-would you please give me a simplified example of Encapsulation and Ploymorphism?
2-either both of the fore-mentioned techniques were applied in my java code" the one you corrected to me"??

thank you
i'm trying to find out
