As you know, Tencent QQ has a very useful "friend cloning" function, users can easily copy the number of contact list to another number. But this service is only open to member users, ordinary users can not enjoy. Microsoft Windows Live Messenger (hereafter: MSN), actually has the same function, but not charge any fees. First, the user login needs to "clone" the contact list of the MSN account, click the "Contact" menu, select the "Save Instant Messaging Contacts" (see Figure 1) Figure

Single-Case modeThe simplest, but also very difficult.To ensure that only one instance exists in a JVM, consider the following: Java can build objects using those methods Is Java still able to create only one instance of multithreaded concurrency when creating objects Java methods for creating objects: New is most commonly used, and is created directly using the constructor. New instances are generated each time they are created. So the singleton should only be new onc

Introduction:With the rapid development of web-based educational products, online education researchers have again put their eyes on the diagnostic methods of psychology, such as the more famous is CTT (classical test theory) and IRT (item response theory), The classical test theory and the project reaction theory are two models. It is much easier to fit than IRT,CTT.Traditional measurement methods for single-attribute diagnosis has been done very wel

We need to do the data encapsulation, the application of writing AH. Otherwise our data message is how to come, is through lwIP for Mac, IP, a
