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
