HandlerClass problem. Please help

[Ceecar12]

Hello

I have a problem with a HandlerClass. I use Eclipse and what ever i do, it still wont work. I am not the greatest at Java, but i really cant se the fault.

Will someone please tell me what is wrong with this programming. The problem is between is at line 72. The program says:

Exception in thread "main" java.lang.Error: Unresolved compilation problem:
No enclosing instance of type Quizzen is accessible. Must qualify the allocation with an enclosing instance of type Quizzen (e.g. x.new A() where x is an instance of Quizzen).

at Quizzen.main(Quizzen.java:72)


PS. I am from Denmark, so some of the "println" statements has danish writing in them, but that should not be a problem, because they work fine.

You cannot instantiate a non-static innner class outside of an instance of the class in which it is declared.

But how do i solve the problem?

[Ceecar12]

What do i have to do for make an action. I need that handlerclass, but i dont where to put it, so the program works.

[Ceecar12]

I am still lost in this problem. Can someone help?

[Tolls]

I'd rewrite it, personally, but for an instant "fix" just make that Handler class static.

public static class HandlerClass ... etc etc

Thank you so much Tolls

And Tolls will admit that this is an ugly fix at that. Consider creating true object oriented compliant classes.
