interface I1
{
void show();
void display();
}
class A implements I1
{
public void show(){System.out.println(“Hi”);}
public void display(){System.out.println(“Friend”);}
}
public static void main(String [] args){
A o=new A();
o.show();o.display();
}
}

Probleam: Multiple inheritence concept ignore this case.why interface used? Bcoz declare two methods declare in interface and a class define those methods.if this class remove line Implements I1 then also class just same work .Then this case what benefits of used interface????

Plz tell me extra benefits of interface used (concept multiple inheritence exclude)
