when i tried to download that exam it is showing an error message..

Is it possible to define a class inside an interface ? I read that we can declare public abstract methods and final variables inside an interface but i never came across any code which defines a class inside an interface. please explain me.

Iam planning to take Java Standard Edition 6 Programmer Certified Professional Exam(IZ0-851). while taking the mock exams i find many questions on borderlayout topic. I don't find these topics in kathy sieera book and also they are not present in the exam topic . My question is should i expect these topics on real exam? How much score do i need to get in mock exams in order to pass my exam? please tell me

Thank you ujjawal

public class TryMe {
public static void doStuff1(List<Empty> list) {
// some code
}
public static void doStuff2(List list) {
// some code
}
public static void doStuff3(List<? extends Empty> list) {
