在需要的地方使用對應的方法
private void factory(){
//靜態代理
? ? ? ? ManToolsFactory manToolsFactory =new AaFactory();
Mark mark =new Mark(manToolsFactory);
//靜態代理
? ? ? ? mark.saleManTools("D");
//靜態代理
? ? ? ? WomanToolsFactory womanToolsFactory =new BbFactory();
Aliven aliven =new Aliven(womanToolsFactory);
aliven.saleWomanTools(10f);
//動態代理
//舉例1
? ? ? ? WomanToolsFactory womanToolsFactory1 =new BbFactory();
MarkCompany markCompany =new MarkCompany();
markCompany.setFactory(womanToolsFactory1);
WomanToolsFactory employ1 = (WomanToolsFactory)markCompany.getProxyIn();
employ1.saleWomanTools(12f);
//舉例2
? ? ? ? ManToolsFactory manToolsFactory1 =new AaFactory();

ManToolsFactory employ2 = (ManToolsFactory)markCompany.getProxyIn();
employ2.saleManTools("111");
}
