It is not possible to cast the keywords this and super, right? Just like what was done in option 1? And it would specifically give out an error saying "not a statement"?

What happened when you tried it out?

What si the difference between hidden and shadowed variable?

[admin]

Try this: https://techsymphony.wordpress.com/2011 ... g-in-java/
or in Hanumant's book, shadowing is explained in section 3.4.2 under "When is this necessary" heading and hiding is explained in section 11.1.2

I read the word press article.
What is the difference between hidden variables and overriden method?

Not sure what kind of difference are you looking for. One is a variable and one is a method. There is nothing like "overridden variable" if that is what you are asking.

Also, the questions that you are asking are too basic. You really should read a book from first page to the last page very carefully and very patiently. Only that can set your fundamentals straight.

I think some fundamental concepts are not well explain in most of the books and then you learn about it only from these exam questions(answers) .

[admin]

That is possible.
BTW, overriding and hiding are explained in detail in Section 11.1.2 of Hanumant's book. Let me know which part is not clear so that we can improve it.

hi Admin,

slightly modified version of fasty23's :
class C extends B {
public void perform_work(){ }
public void instanceMethod() {
A a = new A();
a.perform_work();
}
}

In this context the a's perform_work method is called from C's instance method, isn't it?

Yes.
