Static proxy mode

//  Static proxy pattern 
/* * Real objects and proxy objects should implement the same interface  *  The proxy object is to represent the real role  * */
//  benefits ：
//  Proxy objects can do a lot of things that real objects can't 
//  Real objects focus on doing their own things
