Hello. I have come across a null pointer exception in my code. I understand this is got if there is no class/method/variable being referred to but in my case, I have a method in another class that is supposed to be called. However, the exception is thrown at the where I call it..

classB.getVar();

and this is the method skeleton in the class "classB"

public voidgetVar(){
		
}

Hope this can be helpful enough..I will post any more code if needed..
ps..Am not using actual method and class names for discretion purposes..

As you've been told on Sun, "classB" is null at that point.

thanks...checking it out
