短视频带货app开发，java外观模式Facade实现的相关代码

外观类代码

handlebars

public class ShapeMaker {
   private Shape circle;
   private Shape rectangle;
   private Shape square;
  
   public ShapeMaker() {
      circle = new Circle();
      rectangle = new Rectangle();
      square = new Square();
   }
  
   public void drawCircle(){
      circle.draw();
   }
   public void drawRectangle(){
      rectangle.draw();
   }
   public void drawSquare(){
      square.draw();
   }
}

 

使用外观类

handlebars
public class FacadePatternDemo {
   public static void main(String[] args) {
      ShapeMaker shapeMaker = new ShapeMaker();
  
      shapeMaker.drawCircle();
      shapeMaker.drawRectangle();
      shapeMaker.drawSquare();      
   }
}
