Why am I getting no such constructor when it is defined in my class?

[phpuser123]

I just happened to learb about interfaces. It drew me to implement this little code.
But I am getting some error when I a m instatiating a video object in my videoclub class, there is some error stating no such constructor defined although it hs been defined .

Why am getting such an error?

public class intf {
public static void main(String[] args){
	System.out.println("Hello world");
}
}
interface VideoClub{
	String ba="VideoPradise";
	int area=100;
	public static video[][] cat=new video[5][5];
	public static int num_videos=0;
	
	public void addvideo(String name,int quantity,float price);
	public void deletevideo(String name,int quantity);
	public void updatevideo(String name,int quantity,float price);
	
}
interface Video{

	
	
}

class videoclub implements VideoClub{
	public void addvideo(String name,int quantity,float price){
		 VideoClub.cat[0][0]=new video(name);
	}
	public void deletevideo(String name,int quantity){
		
	}
	public void updatevideo(String name,int quantity,float price){
		
	}
}
class video implements Video{
	public String name;
	public int qtn;public float price;
	public void video(String name){
		this.name=name;
		
	}
	
}

You're missing a videoclub and video constructors, eg
videoclub(){}

video(){}
