why i still receive these errors

this code gives me the following errors,
why?

First of all, have a look at the below points:

1) Use

Code Java:

---

code goes here

---

when you post your code.

2) Don't create new threads for same problems. You were supposed to post these errors on your previous thread only.

Now, coming back to your errors, they are the same. Even after clearly mentioning your errors, you are not accessing the methods in the right way.

sw.getDimX is accessing variable named getDimX [which doesn't exist in your code].

sw.getDimX() is accessing method named getDimX(). [Notice the bracket ().]

So either declare the variables getDimX and getDimY or access the methods in right way.

Please check the solution provided here

Hope thats clear!

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"??

There are so many reference sites providing the information about java's OOPS concepts. You can refer to any of them.

For now, these are the two links which I find useful for starters.

For Polymorphism : Click here
For Encapsulation : Click here

Hope that helps!
Goldest

And I have deliberately not commented on your second point above,
2-either both of the fore-mentioned techniques were applied in my java code" the one you corrected to me"??

Because I want you to find it out on your own. After reading good documentation about OOPS, you will be surely able to find that out.

Best of luck! :-bd
Goldest

thank you
i'm trying to find out

You are Welcome and let us know when you find it out. :)
