No static member can use a type parameter declared by the enclosing class. For example, all of the static members of this class are illegal:
class Wrong {
// Wrong, no static variables of type T.
static T ob;
// Wrong, no static method can use T.
static T getob() {
return ob;
}
// Wrong, no static method can access object of type T.
static void showob() {
System.out.println(ob);
}
}
You can declare static generic methods with their own type parameters.
