NBA之外观模式

Design Pattern:

Facade pattern hides the complexities of the system and provides an interface to the client using which the client can access the system. 模式：外观模式主要目的是隐藏系统复杂性,给客户端提供统一的入口

故事场景：

Curry

  public interface Player {

      //运球
      void gribble();
      //过人
      void crossover();
      //投
      void shoot();
  }

    public class Curry implements Player {

        @Override
        public void gribble() {
            System.out.println("1.运球过半场");
        }

        @Override
        public void crossover() {
            System.out.println("2.在半场过了欧文,詹姆斯的围堵");
        }

        @Override
        public void shoot() {
            System.out.println("3.三分出手,命中!");
        }
    }

外观类 用来封装复杂的业务逻辑

  public class Facade {

      private Player player;

      public Facade(Player player){
          this.player = player;
      }

      public void point3(){
          player.gribble();
          player.crossover();
          player.shoot();
      }
  }

实验的开始

    public class FacadeDemo {


        public static void main(String[] args) {
            Player curry = new Curry();
            Facade facade = new Facade(curry);
            facade.point3();
        }
    }

结果
