Static Binding (Early Binding) vs Dynamic Binding (Late Binding)

　　绑定：一个方法的调用与方法所在的类关联起来。java中的绑定分为静态绑定和动态绑定，又被称作前期绑定和后期绑定。

　　静态绑定：（final、static、private）在程序执行前已经被绑定，也就是说在编译过程中就已经知道这个方法是哪个类的方法，此时由编译器获取其他连接程序实现

　　动态绑定：在运行根据具体对象的类型进行绑定。

staic binding is a binding in which name can be associated with the class during compile-time;and it is also called as ealy bingding
