the super keyword in java generic programming is used to declare a template of a specific type. e.g.
List<?
super MyClass> list =
new LinkedList<AnyTypeDerivedByMyClass>();

編輯 收藏int (*test(char *(*)(void)) (int); declares a function named "test" which accepts a pointer to a function accepting no parameter and returning a char pointer, the function "test" returns a pointer to a function which accepts a integer parameter and returns a integer.
Note: a declaration declares either a variable(pointer) or function(pointer), if its name is followed by left parentheses, it is a function, otherwise it is a variable(pointer).

don't get trapped when reading source code of a complex module, first figure out what the module does/its main functionality and its interfaces, once you get into details, you cannot see the module as a whole and forget its main functionality, if you recognize you are trapped in details, try to come out and focus on interfaces, top->down->top->down

The crucial part in design/programming, is to break down complex things, anything should be easy when broken down to manageable pieces, and, only when broken down, can it be easy. when doing so, the most important thing is to think about the granularity and the relationship between every pieces/modules, again, reasonability.
