here error in pdf

static void initialize(){} // will not compile because overriding method is static

replace with

static void initialize(){} // will not compile because overriding method is instance

[admin]

No, it is correct. The overriding method is indeed static.
But it would be more clear if it said,
static void initialize(){} //will not compile because the overridden method is instance.

yes you are right!
