Facade Method

A Design Pattern for code structure. Involves creating a facade class for clients, that abstracts the complexities of all the subsystem classes.

Example

public class Facade{
	Screen s;
	Light l;
	Projector p;
	public watchMovie(){
		s.on();
		l.dim()
		p.on();
	}
}
 
public class Client{
	Facade f;
	public void  watchMovie(){
		f.watchMovie();
	}	
}
