Hi,
Can anyone tell me what is wrong with this code? It seems to be throwing me some error: non-static method getName() cannot be referenced from a static context.
public void printOrders()
{
for(Order filename: Orders) {
System.out.println("Name: " + Order.getName());
System.out.println("Quantity: " + Order.getQuantity());
}
}
Jump to PostOrder is the class name. YOu use it to refer to static variables and methods of the class. If those are instance (non-static) methods then you need to call them with an instance of the class, eg filename

Oh, thanks that was a silly mistake. Just wondering what are static variables?
They have just one value for the whole class, ie they are a single var that's shared by all the instances of that class. Lots more details in the tutorials...

Thanks again.
