Private variable problem

Hi All,

I want to access a varible form my super class. But i am having problem to access that.

Below is my code :

If i declare varible as 'Private' then i am not able to access it but when i declare it as 'Protected' then it is accesible.

I dont want to break the encapsulation.

How can i access it when it is declared as Private.

am i undersatnding correct it or i am doing something wrong ?

Please shed some light on it.

Thanks
Joseph

You will need to change A to provide access either by making the variable protected or by adding an accessor method e.g. :

You can use getters & setters to access that variable.

Thanks for your replies ..

How do i do with getter and setter ?

Can you please provide some example .

Please note only problem is i dont want to break encapsulation.

if i will use protected then varible is visible out side the class.

Joseph:

You probably just want a getter. Just move your getPrice() method from class A to class B. Extending classes already breaks encapsulation. If encapsulation is what you are concerned about, you should probably use composition rather than inheritance.

Paul Sturrock has provided an excellent example which maintains encapsulation.
