Thanks for the link!

It is from the Exam Lab.

public class Test { public int i = 1; public int getI() { System.out.println("super"); return i; } public static void main(String... args) { Test a = new Arabik(); System.out.println(a.i + " " + a.getI()); } } class Arabik extends Test { public int i = 2; public int getI() { System.out.println("sub"); return i; } }

This prints 1 Sub2. Why doesn't it print 2 Sub 2?

Thanks.

I've been taking the Sun ePractice exams and have been scoring pretty high on those. (The ones you can buy for $75 on Sun's training site).

However, I am not scoring well at all on Devaka's tests. Has anyone who's taken the SCJP test also taken the ePractice exams on their site? If so, how do those stack up to the real thing?

I was thinking I was doing well, until I took some of Devaka's exams.

With that said I'll follow up on what some others have commented on, Devaka. I would really like to be able to do a question, review my answer, and move to the next question. It takes hours to take a full test, and I can't sit there and review all my questions in depth after I immediately take it. The tests I've taken aren't saved, so I have to leave it open until I'm ready to review.

Thanks again!

Can someone please explain to me why this works:

public class testEnum { enum CoffeeSize { BIG, LARGE, HUGE } private static CoffeeSize size = null; public static void main(String[] args) { System.out.println(size.BIG); } }


size is null, but printing a value? No NullPointerException is thrown.

Thanks for the explanation.
