Got trouble with the scope....

Question

Hi,
I have a program, and I have trouble with the scope.
I created two nodes, and I can print them out within that sort of proceedure say
public void a();
//generate nodes and such
but when I do this:
public void b();
//search through the made nodes
it will compile, but will say that there are no nodes created, when i already did by another one, now I know this is a static scope, and I was wondering what to do here?

Answer 1

1) You need to declare the nodes in the class, and assign them in a(). Variables declared outside a method are referenceable within all methods of that class.
2) Get rid of the semi-colons at the end of your method signatures -- the code you've provided won't compile that way.
3) Not to insult you, but you should really spend some time on fundamental programming concepts. Scope is fundamental concept, suggesting that there are some troublesome holes in your knowledge. The more you know, the more efficient you will be.
Bueno suerte.
