A simple and prudent rule of thumb for calculating permissions is the following: The permission set of an execution thread is considered to be the intersection of the permissions of all protection domains traversed by the execution thread. When a piece of code calls the doPrivileged method, the...
Description:In JDK 5.0 and JDK 6,javacerroneously allowed access to private members of type-variables. This is wrong, as the JLS, Java SE 7 Edition, section 4.4, states that the members of a type-variable are the members of an intersection types whose components are the type-variable bound...
For simple message queues, when high reliability is not required, you can use Redis's own publish/subscribe mode or List to implement a queue for asynchronous operation. Friendship, use some commands of the set, such as intersection, union, difference, etc. It is convenient to get some commo...
