带女友干活（代理模式）

老鸟跳过请跳过，

 

最近无聊，贴一些自己过去学习设计模式后，自己写的一些Demo

 

接口：

public interface Do_something {
	
	//做饭
	public void prepare_food();
	//打扫
	public void clean_up();
	//买食物
	public void buy_food();

}

 

具体实现的业务：

 

public class Girl implements Do_something  {
	
	private Kitchen kitchen;
	
	

	public void buy_food() {
		
		System.out.println("买食物");
		
	}

	public void clean_up() {
		System.out.println("打扫");
	}

	public void prepare_food() {
		
		System.out.println("在"+kitchen.getName()+"做饭");
	}

	public Kitchen getKitchen() {
		return kitchen;
	}

	public void setKitchen(Kitchen kitchen) {
		this.kitchen = kitchen;
	}
	
	

}

 

业务类组合的对象类型：

 

//厨房
public class Kitchen {
	
	//谁家的厨房
	private String name;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
	
	

}

 

代理类：

 

public class Boy implements Do_something {

	private Girl girl;
	 
	public void buy_food() {
		
		girl.buy_food();
	}

	public void clean_up() {
	 
		girl.clean_up();
	}

	public void prepare_food() {
	 
		girl.prepare_food();
	}
	//下班
	public void get_off_duty(){
		
		this.buy_food();
	}

	public Girl getGirl() {
		return girl;
	}


	public void setGirl(Girl girl) {
		this.girl = girl;
	}
	
	

}
