Hello. Could you tell me, in one of the tests, it was written that the String and StringBuilder classes are final and that I can not inherit them. And here it is written that the String class has 3 subclasses. How can it be?

I don't see that written anywhere. Can you post a screenshot of where you saw it?
Paul.

Hello. I found it. This is Q_ID: enthuware.ocajp.i.v7.2.956 : "Working with data types" in Quest. 15 of 20 the explanation said:
This will not compile because String is a final class and final classes cannot be extended. There are questions on this aspect in the exam and so you should remember that StringBuffer and StringBuilder are also final. All Primitive wrappers are also final (i.e. Boolean, Integer, Byte etc). java.lang.System is also final.

It is true that String, StringBuilder, and StringBuffer are final. But you claimed, " And here it is written that the String class has 3 subclasses". Where did you see it ? Please post a screen shot.

Hi Paul. Sorry, I'm confused on this issue. I passed the exam today, I got 75. About 6 questions were almost the same as in your "last day's test" ( I got 69 on it ). You helped me a lot, you are very cool, thank you very much !! Stephie.
