6   You can easily google this out. This is not the place to do your homeworks. –  Umang Mehta Sep 8 at 5:29 1   Could you please open up any of the Java books and look at the Inheritance Chapter. Looking at the java reserved key words section will also, give you good answers. If you know that you have to look for final. Let me make it easier for you, open google and type significance of the keyword final in java. – dharam Sep 8 at 5:34 2   Don't get the idea .... why this question is being downvoted ? .... though its a simple question & can be googled .... still if its not in stackoverflow already asked questions .... its a good question to be asked ! .... Also answers in stackoverflow are much better in than google ,blogs and much clear to understand here ! – NewBie Sep 8 at 5:48 You can add finally and finalize to the interview question.

Final Variable: final variable means we can't change its value Final method: If we declare a method as final, we can't override the method. Final Class: If we declare a class as final, that means we can't extend the class or in other words we can't make a sub-class of it Example of final variable: final int distance=8; distance = 7; // because of the final declaration this line is an error Example of final method: public class A { final void LasVegas() { } } public class B extends A {         final void LasVegas() // because of the final declaration in A, this is illegal         {         }     } Example of final class: final class LasVegasClass { } class AnotherClass extends LasVegasClass { // illegal because LasVegasClass is final } share|improve this answer edited Sep 8 at 5:43 Luiggi Mendoza 23.9k51744 answered Sep 8 at 5:27 NewBie 1,0371022
