静态代理模式总结

基本作用：为其他对象提供一种代理以控制对这个对象的访问

首先得创建一个主题类，得是接口

public interface Subject {public void teach();}

然后创建一个实现主题类也就是被代理的类，继承主题类

public class Teacher implements Subject{private String name;public Teacher(String name){this.name = name;}public void teach() {System.out.println(name+"正在上Java课");}}

然后写一个代理类 也得继承主题类

把被代理的父类传过来然后执行Teach方法

public class ProxyTeacher implements Subject{private Subject sub;public ProxyTeacher(Subject sub){this.sub = sub;}public void teach(){sub.teach();}}
