Class variable initialization

Question

I have noticed that class variable initialization occurs AFTER the constructor is called.
Why is this, and is this intentional?
It has caused strange behaviour in my SE java applications I am porting to MIDP.
Thanks

Answer 1

Hi,
Error 1:
The problem only arises if you use the unassigned variable:
int i;
int y = i; // Use of unassigned variable here
you can just assign a value to i to solve this:
int i = 0;
int y = i; // Use of unassigned variable here
Error 2 and 3 have to do with static and non-static, not with the initialization per se. This is how it works:
static members (e.g. fields) can be accessed using this syntax: <Classname>.<FieldName>, e.g:
public static class Helpers
public static int SomeDataValue { get; set; }
class Program
static void Main(string[] args)
Helpers.SomeDataValue = 22;
On the other hand, non-static members are accessed like this: <instance>.<fieldname>. So you always need an instance of a class to access the field:
public class Order
public int OrderNumber { get; set; }
class Program
static void Main(string[] args)
Order o = new Order();
o.OrderNumber = 12;
