8.外观模式

public class Movie {
	public void open(){
		System.out.println("open movie");
	}
	public void off(){
		System.out.println("close movie");
	}
}
public class Radio {
	public void open(){
		System.out.println("open radio");
	}
	public void close(){
		System.out.println("close radio");
	}
}
//利用外观模式，它帮你隐藏了繁琐的步骤
public class Facade {
	Movie movie;
	Radio radio;
	public Facade(Movie movie,Radio radio){
		this.movie=movie;
		this.radio=radio;
	}
　　 　　//一步到位，开始看电影
	public void open(){
		this.movie.open();
		this.radio.open();
	}
　　　　//一步到位，关闭所有
	public void close(){
		this.movie.off();
		this.radio.close();
	}
}
