以无功能值参数，如Java的面向对象的编程语言，[回调]可通过使一个抽象类或接口，其中接收器将调用一个或多个方法来模拟，而主叫端提供一个具体的实现。这样的对象是有效回调的包，再加上他们需要处理的数据。他们是在执行各种设计模式，如访客，观察员和战略是有用的。

解决方案

i want to know want it means to tell us technically

http://en.wikipedia.org/wiki/Callback_%28computer_science%29

"In object-oriented programming languages without function-valued arguments, such as Java, [callbacks] can be simulated by passing an abstract class or interface, of which the receiver will call one or more methods, while the calling end provides a concrete implementation. Such objects are effectively a bundle of callbacks, plus the data they need to manipulate. They are useful in implementing various design patterns such as Visitor, Observer, and Strategy."

how i can manage the callback of the applications

I have no idea what this means.
