Accessing a static variable from a generic class?  RSS feed

class MyGeneric<T>
{
static int i;
---- Other stuff ----
}

class TestGeneric
{
public static void main(String[] args)
{
System.out.println(MyGeneric<String>.i);
}
}

Gives a compile-time error:
illegal start of expression - System.out.println(MyGeneric<String>.i);
^

What is the problem?

Generics are a compile-time artifact. In your example there is only one "MyGeneric" class at run-time and only one instance of the static variable "i". Mentioning the class parameter when trying to access it is pointless and hence wrong.
