class Z

ia[0] = 3;

causes compiler error

Please explain, somebody, thanks. (Uh, feel like a numbskull....).
Erm, I just half-figured it out...
This compiles without errors:
class ZZ
{
public static void main(String[] args)
{
int[] ia= new int[3];
ia[0] = 3;
}
}
Now, the question still is, why does Z.java not compile?

That's not particularly helpful.
It's something to do with making assignments to member variables (as in Z ia must be a member variable, whereas in ZZ it's a local variable) outside of a member function *I suppose*, but I don't know *exactly*.
Now, either you know, but are not willing to help, or you don't know, and can't help. Which is it?

Thanks.
For anyone interested, I just discovered that the code in Z.java can be modified slightly to make it work, but putting the assignment in an instance initialization block:
class Z
{
int[] ia= new int[3];
{
ia[0] = 3;
}
}
The code now compiles without errors.
