设计模式之模板方法模式

来源：互联网发布：无线电频率测量软件编辑：程序博客网时间：2024/06/06 10:42

ClassLoader就是模板方法模式，我的微信公众号也使用了模板方法模式

算法框架已经搭建好，你只需要实现你不一样的东西就可以了。

public abstract class AbstractPeople {

   private void getUp(){
       System.out.println("起床了");
   }
   protected abstract void haveBreakfast();
   protected abstract void transport();
   private void sleep(){
       System.out.println("睡觉了");
   }
   public final void dayLife(){
       System.out.println("=============================");
       getUp();
       haveBreakfast();
       transport();
       sleep();
       System.out.println("=============================");
   }

}
public class PeopleAAA extends AbstractPeople {

   @Override
   protected void haveBreakfast() {
       System.out.println("吃三明治");
   }

   @Override
   protected void transport() {
       System.out.println("坐小汽车上班");

   }

}

public class PeopleBBB extends AbstractPeople {

   @Override
   protected void haveBreakfast() {
       System.out.println("吃面包");
   }

   @Override
   protected void transport() {
       System.out.println("坐地铁上班");

   }

}

public class PeopleCCC extends AbstractPeople {

   @Override
   protected void haveBreakfast() {
       System.out.println("吃黑面馍馍");
   }

   @Override
   protected void transport() {
       System.out.println("坐公交车上班");

   }

}
测试
public class Client {
   public static void main(String[] args) {
       AbstractPeople pA = new PeopleAAA();
       AbstractPeople pB = new PeopleBBB();
       AbstractPeople pC = new PeopleCCC();

       pA.dayLife();
       pB.dayLife();
       pC.dayLife();

   }

}
