Hi,

How are you tring to find the variable xx of class th3 in class proc?

You should have instance of class th3 or some other way to access the variable.
I would suggest you to read chapetr on scopes and varibles.

hi nitin

in your code you have two different classes, which are not related to each other in any way. if you want the variable xx to be accesed in other class you can either write :

"class <first class> extends <second class>

so that there is a relation established in them.
Otherwise the only option will be to create an instance of the other class and then access that variable through this object/instance.

bye
